RP Race 47mm Throttle Body Replacement Yamaha YFZ450R / YFZ450X

RP Race direct replacement throttle body for the Yamaha YFZ450R and YFZ450X. Fits the stock manifold and stock or aftermarket intake, plugs in to the stock wiring harness and uses a manual idle control valve for a precise idle.

47mm bore give instant power gain across the powerband, but requires air-fuel adjustment via a VORTEX controler. Works great in stock or modified engines.
