Upgrade your motorcycle's front end with the YSS Z1 cartridge kit, completely upgrading the internals of its forks. The YSS Z1 is an open cartridge system that gives the rider far better damping control and far better feedback from the front end. It improves the motorcycle's comfort and safety thanks to the improved feedback and stability at the front. The Z1 kits also let you tailor the front-end set-up to your own preferences, whether you use your motorcycle on the road or on track. Have you ever braked on the approach to a corner and ended up with an unsettling wallow? Or does hitting a square-edged bump and feeling as though your wrist will break ring any bells? Riding a motorcycle that is too hard or too soft is a long way from ideal. By creating stability at both low and high speed, YSS Z1 open cartridges are ideal for riding in town and on the open road, since they offer more control and fewer worries. The damping curve on the Z1 cartridges can be tuned more precisely than on other alternatives. Suppose, for example, that you are perfectly happy with how the fork performs at high speed but less happy with its stability at lower speeds. You could then adjust the low-speed behaviour without affecting what happens at higher speeds. High-flow compression and the rebound adjuster guarantee excellent grip in all conditions. The spring preload adjuster lets you set the perfect balance on your motorcycle, for better handling and more balanced cornering. Invest in an open cartridge
