IMPORTANT NOTE - THESE AFTERMARKET CRANKSHAFTS WILL REQUIRE USING A MANUAL LOCKOUT DUE TO THE DESIGN OF THE ONE-WAY CLUTCH. The stock one-way clutch during engagement and dis-engagement causes an excessive amount of stress on furthest part of the crankshaft and can over time create a weak point which in turn may see a failure with aggressive riding.
