This gearing setup helps deliver quicker launches and faster acceleration through the gears, allowing the motorcycle to reach its redline more quickly while maintaining familiar handling characteristics. The combination of lightweight components and race-oriented gearing supports improved throttle response for track and competition use.\u003c\/p\u003e\u003cp\u003eManufactured by RK and supplied under the Driven performance line, this kit provides a coordinated chain and sprocket solution rather than requiring individual component selection.
