YFZ 450R/X Crankshafts

Geisick Performance now offers a variety of stroker cranks for the fuel injected YFZR/X 450's. From the drop in +5mm crank to all out drag 72mm cranks we have you covered. The best part is these cranks have been engineered with reliability and performance in mine, then dyno and field tested to be proven reliable setups with big power capabilities.

Unlike many other stroker cranks on the market Geisick Performance crankshafts come with long rods to maintain a good stroke to rod ratio. Even the drop in +5mm crank has a rod ratio similar to the 06-13 YFZ 450 from the factory. This provides more power with greater reliability for long engine life.
