VOCA Racing is a technical brand based on intense testing in competition and complex engineering. The front disc of the redesigned VOCA silencers (gear-bikes) are now laser engraved with a fine technical drawing that reminds of the lines of a rev-counter. The same drawing is repeated on the bracket of the body of the silencers. Technically the VOCA silencers assure best results regarding sound and performance. All VOCA Big Bore 90cc, VOCA Cross Carbon 80cc and VOCA Carbone 70/80cc are now delivered with VOCA Evo 2017 carbon silencer. As well available as an accessory.
