The Yoshimura MX Tuner is the hot ticket for adjusting fuel injection and ignition timing on your RMZ450/250. In fact, the MX Tuner is a necessity. The MX Tuner provides a smooth and consistent power curve, with maximum power lasting longer at the higher rpms.

The MX Tuner will allow for +/- adjustment of fuel injection and ignition timing at various operating points along the rpm range and throttle position. This degree of adjustability allows the user to take complete control of their engine mapping, enabling the rider to fine-tune the engine to their riding style.

The MX Tuner is stand-alone adjustment device that simply plugs into a port on the stock wiring harness. When tuning is complete, simply unplug and the rider is on their way. A 12-volt battery (not included) is needed to power the device.
