Attention! Only made for MHR Team crankshaft unsplined! With the MHR vario 2005 you are optimally equipped to get the most out of your engine. As compared to a common Multivar, the MHR 2005 vario allows for much smoother engine running and thus easier adjustment thanks to its 19x15.5mm rollers. Different angles and optimised roller curves ensure an increase in performance as compared to common sport variators. A must-have for strong engines.
