■Front Spring
A lowdown spring unique to Hyperpro that lowers the vehicle height by changing the rate and adjusting the oil level without significantly changing the free length of the spring.
Enjoy the smooth ride of the constant rising rate, which softly absorbs shocks and maintains stability at the end of the stroke.
The front spring comes with the necessary amount of fork oil.

*After installation, the vehicle's balance will change significantly. Always adjust the front and rear settings before riding.
*Lowdown parts are considered designated parts, so no structural modification procedures are required.
*For lowdowns of 30mm or more, a short side stand may be required depending on the vehicle's condition. For models with preload adjustment, adjust the lowdown amount so that the side stand can be used while performing the settings.
