G2 Ergonomics Yamaha XVZ1300 Royal Star Tour Classic 96-13 Throttle Tube Only

Features:

• Even out the abrupt initial power delivery to eliminate throttle snap that's especially evident with modern EFI bikes
• Introduce a non-linear ratio between hand throttle and the carb or throttle body opening
• Throttle cam's radius is reduced initially, which requires the rider to rotate the throttle slightly further to get the same opening position as stock; the radius increases after half-throttle to keep the full throttle position at or near stock
• Include a 400 throttle cam and a machined billet aluminum throttle tube with a knurled surface
