The XRAY 320905 - XB2 5G Gearbox Conversion Kit provides a precision gear upgrade for XB2 models. It is tailored for racers who want quicker response and are prepared to maintain the gearbox regularly for best results.
The 5G conversion reduces mass and improves drivetrain response for sharper handling and faster transitions. It gives a clear performance edge on smooth circuits but will demand more frequent servicing under heavy use.
Apply #106210 - HUDY Graphite Grease to all internal gears and clean components before relubricating. Check and adjust the slipper so the front tyres lift slightly at full throttle, and inspect gear teeth for wear after each running hour.
