Description

Reduce the throttle input required to reach maximum power with our easy-to-install WORX Quick Turn Throttle Tube. We decreased the throttle rotation by 8 degrees, enabling you to reach full throttle without compromising your body positioning or wrist position during intense racing conditions. The laser-sintered construction is designed to be used with 123-125mm long grips, while the built-in perforations may make it easy to trim the throttle tube length down for use with shorter grips, ensuring a painless installation on your race bike setup. Rest easy knowing that the reduced rotation was specifically chosen to prevent the need for reflashing your Yamaha's ECU, while still providing quicker throttle response with noticeably less wrist input.

Important Note: Installing this throttle tube will disable the cruise control cancel function activated by rolling the throttle forward (reverse throttle). Cruise control can still be disengaged by activating the brake, clutch, or toggling the cruise control button.
