*When using the side stand, park the vehicle on a flat surface in first gear. (The vehicle will be more upright than normal due to the lowering.)
*After installation, the vehicle's balance will change significantly. Always adjust the front and rear settings before riding.
*Lowering parts are designated components, so no structural modification procedures are required.
*For lowering by more than 30mm, a short side stand may be necessary depending on the vehicle's condition. For models with preload adjustment, set the lowering amount to allow the side stand to be used.
