RIVA Racing’s new 65mm Yamaha SVHO throttle body delivers significant power with all levels of engine modification that was co-engineered with AT Power Throttles, a leader in drive by wire throttle technology.

The 65mm Throttle Bore offers a massive 82 percent increase in aperture cross sectional area over the original OEM unit.

The “shaft-less” throttle technology offers minimal disturbance to the airflow at full-open and part-open throttle, due to the absence of a shaft across the bore and a 2 mm knife-edged throttle blade. Independent tests have shown a typical 1 CFM drop between fully-open and no blade at all.

Installation is simple, with full instructions provided with each kit. Disassembly of the OEM unit and installation of internals into the new housings can be completed in less than 15 minutes using basic tools and minimal DIY experience. The throttle requires minor port matching of OEM intake manifold for optimum performance.

MSRP: $1,199.95
