If you follow what your mother has been telling you for years - anything that looks fun is probably dangerous - then you would never even consider getting on a moped. However, not only do mopeds look super fun, they are also super safe.Although many components of mopeds differ significantly from more traditional vehicles, they are still constructed with a sufficient number of features that help maintain a proper amount of safety for riders.

Mopeds feature bright lamp systems that provide a clear route to follow and illuminate the bike well enough to be seen by all the other nearby and approaching vehicles. Plus, they also feature sealed drum brake systems, which will not fade in wet conditions. However, this should only provide you with confidence in certain situations where you have no choice but to travel on wet roads. If you do have the option, try to wait out the wet weather before you hit the road. And most mopeds feature wide tires (if not, you can easily customize or upgrade later), shock absorbers and a low center of gravity through the weight of the engine. These factors all contribute to increase maneuverability and stability.

Another factor that is not often mentioned that you should definitely consider is your height and weight. Although purchasing a moped online will grant you the best prices possible, you may want to first visit a local moped dealership if you are under a certain height. For those of you who are vertically challenged, you'll want to make sure that you can properly reach the handle bars and that your feet can make solid contact with the running boards. If they can't, then this will put you into a precarious position while riding and will quickly put you off balance, causing you to swerve and crash. In addition, individuals with significant body weights may want to consider another mode of transportation because inertia increases with weight, making turning more difficult and potentially dangerous.

It should also be noted that just because mopeds are not ruled as a major vehicle doesn't mean you'll be exempt from certain laws. Heck, if people can get arrested driving a motorized barstool a few blocks while under the influence of alcohol, you can definitely get nailed for driving a moped under the influence. With a good amount of responsible thinking before you start drinking, you can stay safe and live to ride another day.

Expansion chambers are mainly used in the motorcycle exhaust systems which use two stroke engines. The main purpose of these expansion chambers is to improve the power and performance of the two stroke engines. By using an expansion chamber one could easily get the power, efficiency and performance of four stroke engines. By using the remaining energy of the combusted exhaust which is deliver out of the cylinder, it delivers the extra amount of power, thus it is a recycling method of utilising the power from remaining power present in the exhaust.

The main components of an expansion chamber mainly consist of blow down section, transfer section and a port blocking section. In a stroke engine when the piston moves down, the fuel exhaust is pushed out due to its own thrust and pressure in to a pipe of constant diameter and the pipe forms the initial portion of the expansion chamber equipped in the exhaust system. This pipe is called the head pipe of the expansion chamber of the motor cycle exhaust system. It is kept of constant diameter because the power present the exhaust is kept constant which is utilised in the end cycle of operation carrying out by the expansion chamber. The transfer section consists of a divergently shaped diffuser. This divergently shaped diffuser is divergent at an angle of six to twelve degrees and allows the motorcycle exhaust gas to expand. This divergent section of the transfer section pushes the exhaust to the port blocking section. The port blocking section is convergent in shape at an angle of about eight to sixty degrees as per the requirements of the motor. Thus this convergent section of the motor cycle exhaust system pushes back the fresh exhaust back into the cylinder just before the compression cycle of the piston at high pressure. This type of exhaust exhaust system also consists of a stinger which is used for controlling the exit of exhaust gas as well as help in improving the pressure of the exhaust gases. The different methods adopted to carry out the construction of expansion chamber are the hand-forming method, hydro-forming method and the stamping method.

Since the head pipe of the expansion chamber of the motor cycle has the fresh and hottest exhaust and the divergent port blocking sections, the expansion chamber ace severe temperature variations as well as sound variations. These factors present in the exhaust system can affect the life and performance of the two stroke engines. This type of exhaust system can even affect the efficiency provided by the two stroke engines equipped in two stroke motorcycles. Because of the large shape and size of the expansion chamber it is usually exposed to stones, rocks, woods and other rigid obstacles present on the ground and surrounding. So in order to keep the expansion chamber of the exhaust system in effective condition regular maintenance and service are required.

Though the use of expansion chambers in the exhaust systems of the two stroke motorcycles has many problems everyone tries to get one in order to get the power of four stroke engines. This type of exhaust system is available at affordable prices in the market which can be easily installed in all types of two stroke engines.

Cruiser bikes including Harley-Davidson, Kawasaki Vulcan's and Honda Shadow's have the option for installing full system exhaust drag pipes. A part of a full system exhaust drag pipes are essentially open tubes made of steel with a chrome plated finish that help to produce peak horsepower in a very narrow RPM band.

The assumption that drag pipes will always increase horsepower is not true and most pipes installed on a cruiser motorcycle will actually lessen the overall horsepower, sometimes by as much as 5-10%. Drag pipes are designed to help improve the airflow through the exhaust system and while this will improve the overall performance of the bike it does not automatically equal more horsepower.

While exhaust pipes do help in diverting exhaust fumes away from the engine and the rider many mechanics will tell you the polished chrome pipes put on Harley's, Honda's and other cruiser motorcycles are more for show than performance. Yes you can achieve an increase in horsepower but usually at a range that few riders will ever see. Exhaust pipes were originally designed for drag racing and unless you are looking to gain an edge on the track these pipes won't offer all that much in terms of high performance horsepower.

However, riders looking for an exhaust part accessory that will produce a deep, throaty growl synonymous with fat hogs and larger cruising bikes should definitely consider custom fit slash cut or full cut drag pipes. When you replace a standard OEM exhaust system with drag pipes you must remember to re-jet the carburetor. If you don't the system can backfire and lead to future problems with valves, pistons and other sensitive engine parts.

Another part to consider when upgrading a motorcycle exhaust system with pipes is baffles. Though some riders mistakenly associate baffles with silencers a high quality baffle may take some of the sharp edge off the noise but won't quiet the bike too much. Baffles help improve the mid-range torque by providing increased back pressure in the pipes.

Motorcycles are not like cars and while someone can drive a car without knowing much about the engine it is recommended that anyone who owns or rides a motorcycle should have a basic understanding of the engine and how to perform minor and temporary repairs. The simple point behind this is that motorcycle engines will fail and being stuck on the side of the road is never much fun. Motorcycles tend to break down more often than cars and most bikers will tinker with their engine anyway to make custom adjustments and install performance parts. Knowing the basics of your motorcycle engine can lead to a quick or temporary fix to get you moving until you can find a trusted mechanic to perform a more thorough repair job.

Because of the job an exhaust does there are a number of problems that can occur with the part and the entire exhaust system. Remember, the exhaust is basically the trash chute for your bike's reaction exhaust gasses and the insides and outsides of an exhaust can get extremely hot when riding. Your exhaust and drag pipes can experience a number of common problems including overheating which will cause a "bluing" effect on the tips of the pipes. Even with polished chrome finishes over time the heat will cause a bluish or black color on the pipes. Though this may appear to be only a cosmetic issue over time the excessive heat can cause parts to deteriorate which can lead to harmful gasses being released in every direction.

Since heat is your major concern consider the different ways you can maintain the temperature in the exhaust so it doesn't overheat and what you can do should the system suffer deterioration or even punctures from excessive heat. One option for preparing bikes in advance is to install high quality chrome plated heat shields. Often double or triple-chrome plated heat shields are designed to fit most standard motorcycle drag pipes and come complete with clips for mounting. Heat shields will provide an extra few layers of protection to lessen the damaging effects from the heat and reduce bluing. Heat shields not only protect the exhaust system but also add a shiny chrome finish to your bike's exterior.

Another tip for preserving the exhaust on your motorcycle is to periodically rotate the pipes if you have twin pipes. Gas doesn't always distribute evenly and if you did a custom install with an aftermarket exhaust it is recommended that you rotate the exhaust pipes so if there is an excess of heat to one side you can moderate the effect it has on your pipes. You should check all motorcycle engine parts on a regular basis to achieve optimum performance but regulating the heat in the engine is your primary concern.

Other ideas for cooling a motorcycle exhaust are to install cooling clamps and to use either a liquid or air cooling system in the engine. You may also want to consider using a carbon fiber exhaust system with a carbon fiber exhaust cover since this material heats up much slower than metal.

Whenever I see one of the new and modern motor scooters traveling briskly along, a brief, sharp pang of emotion traces through my thoughts. A bit of memory causes me to stop for a moment. Although the modern motor scooters are much classier than my first scooter, there is still a connection. The first scooter that I enjoyed for many years was a Cushman and a lot of enjoyable memories return when it come to mind.

Although it was just over six decades ago, the memory is clear as yesterday. Never will I forget the moment I laid eyes on my sparkling blue dream, the first motorized vehicle that I had ever owned. Just slightly past the end of the big world war, I recall that the world had just begun to return to normal. A beautiful fall day, my attention wandered to thoughts of my Cushman that my dad had managed to purchase something in a very difficult buyers market. After years of rationing and shortages of autos, motorcycles ... and scooters ... all were difficult to come by but he managed to order my pleasant imagining dream.

I found it very difficult to keep my mind on whatever my teacher was valiantly trying to propose to the class and my mind continued to wander. Only noting bits and pieces of her instruction amongst visions of my forthcoming scooter, I really was trying to be attentive but it was very difficult. To make it more difficult, my dad was, beyond the obvious station of being my father, was also the principal of the elementary school which I attended earlier in life. Earlier, on passing by to the cafeteria that was in the grade school, I had noted that dad was not in his office as usual and I briefly wondered where he might have been this day. Of course, in his position as principal of the next door elementary school, it was always necessary for him to always be going out on different chores.

My thoughts were brought to life with the appearance of the student proctor appearing in the doorway of the classroom. Barely hearing my name, a strict demand that I should go to the office brought me back to life quickly. Knowing that dad was not in his office, a cold feeling washed over me as I realized that I was being instructed to go to the office, now. Not having any idea of what could be wrong, I quickly picked up my books and nervously made my way to the office of the principal. To say that I was anxious might have been an understatement.

The principal of my high school was a very stern and, I must say, an austere man, of whom I harbored no little fright. Not knowing what to expect, he grimly spoke to me in his firm manner and told me that I must go home immediately. I managed to offer a shaky, "Yes, sir," and hastily made my exit.

It so happens that my home was just a few short yards from the school complex and when I removed myself from the building, my home was in full view. Suddenly, my heart skipped a beat as I could see my dad standing next to a shipping crate in front of my house. Peeking out from between the crate frames, the sparking, shiny, wonderful blue of my new Cushman shone through. My fright turned to rapturous delight and, probably, I made the few yards to home quicker than any time before. My father beamed as only a dad could under similar circumstances. My new scooter had been delivered by the local dray and was waiting for me to enjoy.

Such was the beginning of ventures that was beyond my wildest dreams. I found myself enjoying a sense of freedom that I had never know before. Just of a tad of a boy, I suddenly discovered a new world filled with adventures far, far past what I had ever known before. Suddenly, I was able to venture past the closeness of home and family. Suddenly, I became a part of the world that had never been available to me. Like a normal kid, I had a bicycle, of course, but limits kept my close to my abode. Now with my new Cushman scooter, I found that I could enjoy ventures whose results were not always certain but certainly exciting.

Well, such was my introduction to a new Cushman motor scooter and a new world. I really have no idea how many miles I managed to put on the scooter but it did not matter, I guess. I seemed like hundreds or, maybe, thousands of miles and we traversed with a tank-full of gasoline as often as my studies allowed. I sped well beyond the limits that had cooped me in before. With a sense of discovery, my blue scooter and I were suddenly a part of the world and enjoying all about us.

Starting up early in offering various mechanicals for the motorized world, the beginning of Cushman was near 1903 in Lincoln, in the state of Nebraska. Founded by brothers Everett and Clinton, it was officially legalized as Cushman Motor Works in 1913. Initially the company produced an extensive large industrial quantities of engines for farm equipment, various fuel and water pumps, lawn mowers and equipment for boats. Beginning in 1936 and continuing until 1965, Cushman produced a range of motor scooters. Included was a model that was used by the US military. In World War II, scooters were used as a mode of transportation whenever standard vehicles were impractical. Production of scooters came to an end in 1965 and the company picked up slack with golf carts, industrial vehicles and maintenance equipment for turf.

The Cushman Eagle motor scooter, as the most successful product, was continually produced for some sixteen years. Resembling more motorcycle than scooter, it sported an exposed engine and a teardrop shaped top tank. Most Cushman models sported the step-through most common for the style of scooters and adopted as Vespa's standard. Models in the fifties, known as Road King and Pacemaker, sported a more style of the age. Sears and Roebuck even got on the scooter craze with an Allstate. A singular and famous vehicle from Cushman, called the Model 53, was a part of US Army Airborne, which served valiantly worldwide. Intended to be dropped by parachute, it came to be called the Cushman Airborne. Other models served base messengers.

Probably the Trucksters that was produced by Cushman beginning in 1958 and continuing through 2002. A small and light utility vehicle, their utilization include delicacy marketing, maintenance of malls and stadiums, parking control by police and others. Equipped with an automatic, centrifugal clutch, the rider simply had to turn the right grip to go and press a single pedal to stop. Strangely, the throttle grip was required to turn forward to go, completely opposite that which is normal on motorcycles. Step-through design and simple operation was popular with both men and women. Claiming almost 100 miles per gallon, Cushman advertised cent-a-mile operation. Weighing 250 to 335 pounds, some had up to 9 horsepower (6.7 kW). Manufacture ceased in 1965 but some Eagles were sold from 1966 inventory.

Strange as it may seem, a promotional flyers for Cushman scooters in 1937 claim over 100-mpg fuel performance, years before green vehicle was even mentioned. The scooters found their place early on but their wartime heriocs gave Cushman scooters their spot in history.

A movement for creating replicas of the well-known Cushman motor scooters, such as the Eagle, has found a place in our world. An ever-growing group of people that share common interests in motor scooters is growing, and will continue to expand. The company has been owned by several different groups, currently the Textron group from Rhode Island. Other companies owned by this consortium are Bell Helicopters and Cessna Aircraft. At one time, Cushman became a division of the Outboard Marine Corporation in 1962. Ransomes (of Great Britain) purchased Cushman in 1989, and then Textron purchased Ransomes.

No one enjoys wasting time caught in gridlock. How often have you seen a moped or scooter zipping around cars and navigating its way through traffic while you are powerless to do anything but sit and wait? Have you longed to be that carefree individual not affected by the grind of the daily commute? Have you noticed a moped or scooter easily fit into a parking spot while you circle the block looking for a space big enough for your car or truck? With a moped or scooter, you can let go of your inner road rage and discover a better way to travel. Before making your purchase, you may first require information regarding these vehicles, including what differentiates one from the other.

One major difference between a moped and a scooter is the size of the engine and the power capacity. A moped has a small engine and is designated as a vehicle with a displacement under 50cc. In most cases mopeds are limited to top speeds of 30 to 35 miles per hour. As such, mopeds are intended to be driven on roads rather than highways.

In terms of body, a moped strongly resembles a bicycle. In fact, mopeds are typically built as bicycles and then equipped with a motor. Many, but not all, localities require that mopeds include pedals. The inclusion of pedals provides a safer ride and allows for a younger driving age in many places. Additionally, mopeds can often accommodate more than one rider.

In comparison to mopeds, scooters have larger engines and are often designated as vehicles with displacements between 50cc and 150cc. A scooter's engine is typically located in the rear of the scooter underneath the driver's seat. Scooters can travel at much greater speeds than mopeds, which makes them better suited to travel highways.

The body types of mopeds and scooters are similar and both typically have a step through frame. As defined by legislation in the United States, scooters must have a platform for the driver's feet. Another notable difference when comparing the body of a moped and scooter is that scooters are larger than mopeds.

Both mopeds and scooters are popular throughout the world, with mopeds being geared more towards younger generations and scooters being more frequently favored by those looking to save on gas and get more power than a moped without the attitude of a motorcycle. Additionally, both mopeds and scooters have options allowing for customization. As mopeds are more of a skeleton than a scooter, they typically feature more customization options.

One of the longest running debates in the technology world is gas versus electric. This carries over to the decision making process of choosing between a gas moped and an electric moped. This debate may continue long into the future as both types have their own significant merits.

Contrary to what some folks think, electric mopeds run on battery power and do not have to remain plugged in! Hopefully, no one actually believed that, and although battery power doesn't limit you from riding beyond the length of an electrical chord, it can still limit the distance you'll be able to travel. Larger moped models are usually built with a lithium battery system. On average, this system will allow you to travel approximately 50 miles per battery charge while riding at 30mph. This will definitely depend on the terrain. This operation time will dip significantly if your route includes going up any significant hills. However, you'll simply need to plug your moped into an electrical socket to recharge. So it's always a good idea to plan at your route to ensure that there will be a socket waiting for you at the end of the first leg of your trip. On average, these batteries last approximately three years.

Electric mopeds do tend to have a higher initial price tag. However, anyone with some patience will eventually see that they do eventually help you save money. Because they are powered by electricity, you'll never have to chance the oil or worry about maintaining or repairing a transmission. And although electricity costs vary geographically, the cost of electricity is almost always cheaper than gas. This is especially true if you're able to plug in at a public store or shopping center. And one of the biggest benefits touted by the electric models is their environmentally friendly operation. They provide one of the greenest forms of transportation.

On the other side of the coin is the gas powered moped. Although these types of mopeds are definitely not nearly as environmentally friendly as electric models, they still leave a much smaller carbon footprint than cars, trucks, and especially SUV's. One of the biggest pluses about going with gas powered models is that they are more flexible than electric mopeds. Gas powered models can get you from 50 to 200 miles per gallon! Granted, that is a large variance, but it all depends on the type of terrain and amount of traffic you're riding in. Regardless, you will be able to travel further at one time than electric models, making this model the better choice for longer commutes. And if you're dealing with a tight budget, then gas models might prove to be the friendlier option at first as they are cheaper than electric models; almost half the price!

Whether you opt for gas or electric, you can still look forward to great convenience, safety, and performance features.
