DID 428VX:



The development of the 428VX is based on DID's many years of experience in MotoGP and

meets even the highest demands through the use of patented X-rings.

Compared with the V series, which is equipped with an O-ring, the 428VX has higher strength and

greater resistance to wear.



- Long service life and low friction thanks to the patented X-ring
