BAL-BUSA-KNIFE-01 Knife-edge & lighten Hayabusa crankshaft retaining balancer.
The crankshaft will be knife edged, the counter weights lightened and re-balanced to compliment your pistons & rods. We will require these, along with your generator when machining the crank to enable the counterbalances on the crankshaft to match your pistons & rods.

If you are using our new slipper pistons and rods, the new weight of the crankshaft will be approx 10.92Kg compared to 11.35Kg of the standard crank - this may not seem a huge weight saving but many people take this machining process too far thus causing problems. The knife edged crank will give ultra smooth and rapid engine acceleration, the balancer shaft has been retained to further aid the smoothness of the engine which is a highly desirable characteristic on a high revving engine of this type. It should be remembered that if Suzuki could have designed the engine to run without the balancer shaft without any negative effects, they would have!
