Want more control through the turns, a quicker throttle response or a smoother, more progressive feel? The G2 Throttle System lets you choose the throttle response to suit your riding and conditions.
G2 throttles are used by Factory Yamaha teams across Supercross, GNCC and MotoAmerica Road Racing, combining a precision throttle tube with interchangeable cams so you can easily change the throttle ratio.
1. Select your throttle tube
Choose the complete throttle tube with the ratio that gives you the response you want. Go quicker for a more immediate throttle response, choose a tamer ratio for smoother, more progressive power delivery or select a stock ratio to retain the familiar OEM response. Each aluminium throttle tube features self lubricating Delrin bushings pressed into both ends. These eliminate aluminium to aluminium contact, helping prevent galling while providing smooth throttle operation.
2. Choose your housing or use the original
These G2 one-piece throttles can be used with your standard throttle housing, so there is no need to purchase a housing if you don't want to. Alternatively, upgrade to new Domino 3129.03 4-stroke desmo throttle.
