The spoiler can generatedownward pressure, helping tomaintain stability and improveits high-speed performance. By changing the direction and speed of the air flow, the lift force of the rearof the vehicle is reduced, and the adhesion of the rear wheel is increased,thus improving the high-speed stability and handling performanceof the vehicle. By mounting these spoilers you increase the vertical downforce at high speeds, an effect that improve the stability of the bike and reduce the risk of losing control over the front axle. Adjust for improvedaerodynamics. can help reducefriction between the air and theground, thereby reducing drag andimproving efficiency. lmprove stability. The installation is simple and does not require complicated procedures. Fitment: For RS660 2020-2024 Note:Please confirm when placing your order that this product is suitable for your motorcycle.
