Front Fork Springs Road & Track 08423-xx

Our 30 mm front fork cartridge kit is based on experience gained from international Supersport and Superstock championships. It doesn’t matter if you are heading for a national road racing title or if you are taking your bike to the local race track. The cartridge kit will give you loads of performance, stable damping characteristics and fantastic comfort. The kit has a unique design with compression damping and the adjustment on the left leg and rebound damping and the adjustment on the right leg – i.e. all adjustments are made at the top together with the spring preload! The cartridge kit system fits bolt on in most standard hyper sport front forks.

The NIX 30 cartridge kits are delivered without springs. The springs need to be ordered separately to suite customer’s choice of spring rate.
