Kunnen jullie dit plaatje nog herrineren van de 2fast sprinter in italie. Daarop is duidelijk te zien dat er massa is gemonteerd aan de krukas.
Nu kwam ik laatst dit stukje tekst tegen in een groot artikel over bandenkeuze
"The "Mystery Part" in the Factory Suzuki Superbike is in fact a very heavy flywheel weight !!!
That's right, adding weight to the crank can often produce better results !!
Suzuki's not the only company to do this, Kawasaki even offered
5% heavier than stock cranks for their ZX7R Superbike kits.
A heavier crank increases acceleration ??? At first glance it seems counterintuitive.
Until you think about the big picture !!!
In roadracing, most acceleration starts from a point of full lean angle, and near zero extra traction. Accelerating from a serious lean angle is about giving all the power the tire can take, and no more. Any sudden lurches in the power delivery from a super-light crankshaft will just break traction and excessively spin the tire out sideways. This kind of riding usually chews up the
rear tire before a race is halfway over.
Once the rear tire is gone, forget about winning. "
