Yamaha YFZ450R 2009-2021 Custom 450cc/min Fuel Injector Upgrade

Description

After a lot of R&D and dyno testing Geisick Performance has developed a line of parts for the YFZ 450 R/X engines. With the right combination of parts the fuel injected bikes can now make great power as well. The latest is a fuel injector which will keep up with the demand of a built engine, or simply if you want to switch to E85 or methanol as a cheap alternative to race fuel.
Direct bolt in and run 450cc injector (installation instructions available)
Superior fuel atomization resulting in more power than any other injectors on the market, including the stock fuel injector!
Un-matched expertise to setup and deliver exactly what you need.
Stock injectors are maxed out between 55-60hp and this will cause tuning inconsistencies, greatly increases chances of engine failure!
Most precise injector you can buy!
Wide variety of different sizes to best suit every engine! No matter the fuel you will run (pump gas, race gas, E85 or methanol) we have ran and tuned it all and will get you running in no time.
