Quick action twist grips by TOMMASELLI change the transmission of the throttle cable. The grips are designed so that even a 38mm carburettor can be opened in a flash and completely with just a quarter turn.
Conclusion:"Fulllllllllllllll throttle“
SIP TIP: For mounting, the fixed quick action throttle tube must be installed (PART No. 62030000). In addition, order a longer throttle cable with a PFTE sleeve at the same time (PART No 62041000).
