What do swingarm extensions do

A swingarm holds the rear axle in the place and provides a better stability and prevents dips in the road and shock from the bumps. While taking off at high speeds, it provides a better stability and performance by keeping the front wheel on the ground. The performance of the bike is improved to a large extent while using swingarms that helps hill climb bikers and also drag racers.

For many of the riders a swingarm extension helps to give a streamlined look to the bike and hence it is necessary to know whether you are installing it for the function or just the appearance. The swingarm extension to a bike allows the bike to be stretched to max and everyone will be turning their heads just to watch you ride. This will make the bike to look sleeker and even lower even if the bike is not lowered by you. One of the major chassis component of any of the bike is swingarm extensions.

It is also very important to pay a proper attention while choosing a swingarm extension because if the choice is made wrong then it will be really terrifying for you. It is very necessary to understand the process beforehand while installing the swingarm extension. The process involves the steps stated below. Step 1 The initial step for installing a motorcycle swingarm is by placing the bike in a convenient position.

In order to lift the motorcycle rear use a jack. To prevent the lower fairing and side to get damaged, it is necessary to take it off. Until the rear wheel is raised from the ground keep on lifting it.

Step 2 Now hook the strap to the end of the strap and take it over the motorcycle from the other end. Tighten the strap and make sure that the motorcycle is stable. After this remove the axle and loosen the grip from the rear axle.

I assume the pivot point will essentially stay in the same place, but now there is a longer lever taking advantage of that fulcrum point. Under hard acceleration, with the use of a longer lever, would the force that causes the rear end to rise have an extra advantage? If so, I am guessing that extra advantage is enough to either counteract the rise of the front end or significant enough to even push downward on the front end?

Then comes the chain itself. With the longer swingarm, the length of the chain is significantly longer. That means there is more distance between the engine sprocket and the rear wheel sprocket which leaves a greater area for chain slop. I would assume then, while swingarm extensions have a certain coolness about them depending on your tastes , they would require much more maintenance and would be hard on the life of a chain. Is that a correct statement?

Also, would a swingarm extension affect handling of the bike? The engine is the densest area of the bike. Effectively moving it forward makes it harder to lift. Longer swingarms are common in drag racers to help take offs without wheelies and improve straight line stability.

Hill climb bikes also have extended swingarms because the upward angle makes flipping too easy. Extended swingarms make steering slower and the turning radius larger. Most street bikes have them for appearance sake to look like dragsters because looks are more important to their riders than function. When not running in a straight line, handling suffers.

They were also tested on the Bonneville Salt Flats on 2 bikes. I use all Stainless Steel hardware. This one of the bikes that used my extensions on the Salt flats. That is an 80lbs block filled with lead that is bolted to the bottom of the swingarm for traction.

I would think that is a testiment on the strength on my extensions. GixxR Jul. How much for your extensions? McyMike Donating Member.
