Redesigned and Optimized Desmo Valve Shim Kits
We have completely redesigned all shim kits (except the 2V-8mm kit) to better meet the needs of our customers. Based on our years of gathering valve shim use data – each shim kit now includes a range of shims that are most commonly used in a particular Ducati (or range of similar Ducati models). More Info
