Chimera Crankshaft Supporter Yamaha Zuma 125

SKU #: CH-1035
Chimera Crankshaft Supporter and reinforcement for Yamaha Zuma 125 engines. Throughout the years, we've notice that high power Zuma 125 engines have the tendency to break crankshafts on the variator side, and Chimera decided to do something about it.

On the transmission side of a Yamaha Zuma 125 crankshaft, the crank nose for the variator is the weakest point of the crank. Under hard acceleration, the crank nose will acually twist and flex, over time causing the nose shaft to break (if the nose shaft decides to break, your engine will continue running, however the bike will not go anywhere!). Chimera Crankshaft Supporter will stabilize the crank during hard accelerations, preventing major flex from occuring. Chimera Crankshaft Supporter is easy to install and highly recommended for high performance built engines, especially with aftermarket performance cranks. The crankshaft supporter will mount onto the original CVT cover and that's it!


Throughout the years, we've built numerous high performance Zuma 125 engines, from simple 155cc to 280+cc. After breaking a few cranks at the variator nose, we knew there was a problem. We've use the crankshaft supporter on numerous projects, including a 280cc turbo project and a few N/A 210+cc engines! We feel more comfortable with the crankshaft supporter installed and used on high performance engines that we've built. 


NOTE: Will work with most aftermarket variators.
