*When using the side stand, park on a flat surface with the bike in first gear. (The bike will stand more upright than stock due to the lowdown.)
*After installation, the vehicle's balance will change significantly. Always adjust the front and rear settings before riding.
*Lowdown parts are considered designated components, so structural modification procedures are not required.
*For lowdowns of 30mm or more, a short side stand may be necessary depending on the vehicle's condition. For models with preload adjustment, adjust the setting while ensuring the side stand can be used with the chosen lowdown amount.
