XScream + 10mm Stroker Crank

Yamaha 701 +10mm stroker crank (78mm stroke) - We start with quality-certified steel, which produces the highest possible tensile strength and durability. Then, we double heat-treat the crankshaft before grinding the rod and main journals to size.

This crank is build to XScream specifications and uses OEM Yamaha crank bearings. Our XS1000 and XS900R engines use this crankshaft.
