OVERVIEW

For the racer who wants the ideal compromise between the lightweight handling of a 350 and the tractable torque of an open class bike, the 2027 RR Race 390 is a standout choice. This competition ready iteration of the X-Pro lineup introduces a suite of racing derived electronics, including a new handlebar-mounted control panel housing Launch Control and Quick Shift technologies for flawless starts and uninterrupted gear changes. The 390 engine benefits from new titanium valves and a mechanical cam chain tensioner, ensuring immense consistency in all racing conditions. Coupled with updated internal valve settings in the benchmark KYB suspension, a modern LED headlight mask, and a new high output voltage regulator, the RR Race 390 delivers high performance capabilities without inducing rider fatigue.
