Upgrade your motorcycle's front end with YSS's Z1 cartridge kit, fully upgrading the internals of its fork. The YSS Z1 is an open cartridge system that gives the rider far better damping control and feedback from the motorcycle's front end. It improves the motorcycle's comfort and safety thanks to the upgraded feedback and stability of the front end. The Z1 kits also let you tailor the front-end set up to your personal preferences, whether you use your motorcycle on the road or on the track. Has it ever happened to you that you brake as you approach a corner and end up with an uncomfortable wobble? Or does hitting a square-edged bump and the feeling that your wrist is about to break ring a bell? Riding a motorcycle that is too hard or too soft is a long way from being the ideal one for you. By creating stability at both low and high speeds, YSS's Z1 open cartridges are ideal for riding in town and on the open road as well, since they offer more control and fewer worries. The damping curve on the Z1 cartridges can be set more precisely than on other alternatives. For example, let us suppose you are perfectly happy with the fork's performance at high speeds, but not so pleased with the stability at lower speeds. You could then adjust the performance at low speeds without affecting what happens at higher speeds. The high-flow compression and the rebound adjuster guarantee outstanding grip in all conditions. The spring preload adjuster gives you the ability to set the perfect balance on your motorcycle, for better handling and more balanced cornering. Invest in a YSS Z1 open cartridge and give yourself a riding experience that will be safer and more comfortable.
