YFZ450R Pump Fuel Power Up Kit

This package is for YFZ450R owners that don’t want to break the bank or lose the legendary Yamaha reliability, but still want more power, torque and response. A proven package that’s been used for years in MX, desert and trail

Matched with the right exhaust this will give a 20-30% increase across the rpm range over a stock bike (we can help with exhausts too, click here)

*send your head in and we port your head.

We don't do a core/exchange program so you can be confident you wont get someone elses exchange head that might have worn parts such as valve guides or seats.
