Metrakit ProRace 3 70cc Exhaust Beta RR / Rieju MRX / RR

"With the PRO RACE 70 3 Metrakit you get the evolution of their years of experience in competition.
An absolutely "HighEnd" hand-welded and high-quality exhaust.

We recommend it in combination with a 70cc/80cc competition cylinder (e.g. the Manston Revolution, the MHR TEAM, Metrakit ProRace). It is a machine.

It offers the highest performance especially with your new PRO RACE 3 cylinder."
