Extended swing arms — the main part of the rear suspension, holding the rear axle — help prevent the bike from going into wheelie position on takeoff, which can happen unintentionally.
How does an extended swingarm affect handling?
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.
What is an extended swing arm on motorcycle?
Extended swingarms – are often used by drag racing motorcycles (called dragbikes) to keep their center of gravity as forward as possible, which reduces the tendency to wheelie at the start.
How does a single sided swingarm work?
The swingarm has to support the rear wheel, pivot so the suspension can do its thing, and deal with some pretty major loads. … With a single-sided swingarm the axle, sprocket, and chain, all stay where they are, while the wheel just slides off the axle.
What is the purpose of swing arm?
A swingarm, or “swinging arm” (UK), originally known as a swing fork or pivoted fork, is the main component of the rear suspension of most modern motorcycles and ATVs. It is used to hold the rear axle firmly, while pivoting vertically, to allow the suspension to absorb bumps in the road.
What are Swingarms made of?
Swingarms can be built of a variety of materials, the most common among motorcycles being aluminum. Manufacturers also produce them out of steel and — in rare cases for very pricey motorcycles — carbon fiber.
What motorcycles have single sided swingarms?
Ducati, KTM, MV Agusta, Kawasaki, and Honda all have motorcycles with super-trick single-sided swingarms.
How does trail affect handling?
Trail is a combination of the head tube angle and the fork rake and can be thought of as the tyre contact point trailing behind the steering axis. The short explanation is a small amount of trail equals a ‘fast’ handling bike, while greater trail equals a ‘slow’ handling bike.
What is the ideal trail for a motorcycle?
More trail is nice at high speeds (motorcycles usually have 80 mm of trail) but can feel sluggish at slower speeds. Head angle also influences wheelbase and front center, which affect weight distribution. Ideally, a rider should have 45% of the bike + rider’s weight on the front wheel and 55% on the rear wheel.
