Capricorn ONE restrictor set

Capricorn introduce the new ONE restrictor set. Provided in three different heights but all with 9mm diameter, the restrictors have been designed to be used on all Novarossi and OS on-road engines to fine tune the response of your engine. The shorter restrictor is meant to improve the bottom end power, while the longer one increases the top speed, all three giving different feelings to the user.
