The G2 Progressive Rate Trials Throttle tube for Montesa provides increased control where needed off idle, then ramps up to keep overall rotation at a comfortable range. The initial rate is same as the Domino BLACK Trials Throttle Tube, which provides great control. However, the BLACK throttle tube requires far too much turn to reach wide open. By increasing the rate at mid-throttle, rotation is nearly same as the WHITE throttle tube. It’s the perfect compromise between the two!
The throttle tube consists of the ultra-smooth G2 tube with Delrin inserts. The cam (or “pulley”) end is the same rate as the Domino WHITE (Fast) plastic throttle tube.
Interchangeable G2 Cams for Yamaha
Interchangeable G2 Cams for Husqvarna. For newer models with silver housing, all cams are black or white machined Delrin. Some of the white Delrin 200/300/400 “control” cams appear circular from the side, but each has a unique channel that gives the same progressive shape ratio as our other aluminum cams.
