Who makes the trick centrifugal clutch?
Centrifugal clutches have been around forever. The level of sophistication these days is amazing.
Road racers have the opposite problem when they slow for a corner and the rear wheel is driving the engine. They use a slipper clutch to partially disengage to prevent wheel hop.
The stock Hayabusa clutch drive plate has radial springs to help absorb some torque on launch. They help on a stock engine, no help when you are trying to get a decent launch.
How many times have you watched a Bonneville car bog the engine on launch? Not helping the exit speeds, that's for sure.
The Hayabusa drag racing clutches range from single stage like the one in the picture to multi stage with springs and levers and weights and washers and 6 arm and 4 arm oh my.
The clutch doesn't engage until you are up in the low end of the power band. Or the high end, your choice with springs and weights. Problem solved.
