Here are the famous BOYESEN competition carbon fiber valves which can be fitted to many motorcycles. These slats can only be fitted on models after 1980 in SUZUKI TS, DS, TS ER and other 80cc derivatives, or even SUZUKI RM 50cc, 60cc and 80cc in the years 1980 to 1986. These fiberglass valves will allow you to obtain a considerable gain in both torque and high speed.
This is a patented double-blade system, a thinner one for low revs and a thicker one that comes into action (resonance) for high revs! The fiberglass that makes them is of very high quality! Ideal for equipping your unbridled and highly equipped machines. They come with a notice!
