Engineered to the ideal specification for each bike, YSS shocks come ready to install, without any need for further adjustments. Additional features are available depending on the model; threaded spring pre-load adjustment, high and low speed compression adjustment and a easy rebound adjustment are just a few of the stand out features of YSS suspension units. All this gives a package that offers great durability and lasting performance while enabling riders to tune suspension to suit their riding style.
