Buell,
the motorcycle innovators
Fuel carried in the frame, low slung mass centralised silencer, rim
mounted discs, belt drive. It could be a concept bike due out 10 years
from now, but actually you can find these unique engineering solutions
on almost every Buell motorcycle since 2000.
Buell uses three main overriding principles when designing their bikes:
Mass centralisation - positioning all the heavy, bulky components
like the engine, transmission, silencer etc. as close to the center
of gravity and low as possible.
Torsional rigidity - This involves making the frame highly
resistant to flex and twisting forces and keeping the wheels directly
inline at all times, even during the most aggressive riding.
Minimal unsprung weight - Keeping the brakes and wheels as
light as possible to reduce unsprung weight. unsprung weight governs
the inertia of suspension components, affecting their ability to respond
to bumps and changes in direction or road surface. High unsprung weight
has a negative effect on overall handling ability, especially on imperfect
surfaces, like a road.
 These
guiding principles have resulted in the fuel being carried in
the frame to get the weight as low and centered as possible.
A high up conventional fuel tank has a negative effect on handling
when full as it raises the center of gravity considerably.

 The
silencer on all modern Buell's is a triangular affair located
directly underneath the engine, the lowest possible position.
It's curved triangular shape prevents it from suffering scrape
damage during high speed cornering.

The rim mounted discs reduce the unsprung weight of the front
wheel by 3.2 kgs (7 lbs) when compared to quality dual disc
setups.

 Most
sport bikes rely on a chain (which requires regular maintenance)
for final drive from the gearbox to the rear wheel. Buell bikes
use a belt which runs over an idler pulley, this keeps the belt
taught at all times (low maintenance) meaning power is transferred
instantaneously to the rear wheel. (Highlighted) |
