Crank Counterbalancer Dummy Shaft
When you remove the counterbalance gear from a CBR1000RR crankshaft there's no point in keeping the heavy counterbalancer mechanism in the crankcase. You can replace the entire balancer assembly with this lightweight billet aluminum "dummy" shaft. Remove the stock assembly and insert this shaft in its place. The shaft and o-rings block all oil passages.
For use when running an APE race balanced crank with the counterbalncer gear removed.
Fits CBR1000RR '08-'12
