Motion Pro Throttle Kit

Motion Pro Throttle Kits: Precision Throttle Control for Every Rider

When it comes to mastering the connection between your hand and your engine, few brands have invested more engineering effort than Motion Pro. Their lineup of throttle kits is built around one core philosophy: no two riders—or riding conditions—are the same, so your throttle response shouldn't be locked in either. From casual street cruising to aggressive off-road riding and track-day sport biking, Motion Pro has engineered a throttle kit solution designed to fit the moment.

The REV3™: Motion Pro's Most Advanced Throttle Kit

Motion Pro's most popular offering is the REV3™ variable rate throttle kit, widely regarded as the most advanced throttle kit available for both street and off-road applications. Its innovative reel-changing system lets you tailor the throttle rate to your preference and riding conditions—use smaller reels for a slower throttle rate and larger reels for a faster throttle rate.

The included cam reel has a progressive profile, allowing the throttle to act like a sensitive, long-twist throttle during initial small throttle openings for precise control, then acting like a more aggressive short-twist throttle at larger openings. The slim REV3™ throttle housing allows more room for lever clearance and adjustment, while the improved throttle stop provides greater strength and durability. Snap-together elbows make it even easier to install and swap reels.

Lower cable sections use 5 mm housing with a PTFE liner for reduced friction, increased routing flexibility, and lighter weight, while the upper section uses 6 mm housing to provide solid support for the adjusters. Off-road REV3™ kits come with the legendary Titan Throttle Tube™ and are compatible with Motion Pro DirtControl™ V2 Lock-On grips, while sportbike kits include RoadControl™ grips—making each kit a truly turnkey upgrade.

More Throttle Kit Options: Turbo SE, CR Pro™, and Revolver

Motion Pro's throttle kit range extends well beyond the REV3™. The Turbo SE represents a refined evolution of the classic Turbo™ design, featuring a POM pulley with brass bearing for smooth feel and extended wear resistance, with die-cast aluminum construction and a billet aluminum cover. It is engineered with the perfect twist ratio for off-road motorcycles and ATVs, fitting 7/8" (22 mm) handlebars.

The CR Pro™ and CR Pro™ SE are Motion Pro's slowest single-pull throttle options, with a rate of 2.93 resulting from a maximum 170° turn and 58 mm of travel —ideal for riders who prefer a more deliberate, controlled throttle input. The Revolver kit takes a different approach, including four reel sizes and a billet aluminum reverse lever relocation kit, allowing riders to tailor their throttle rate with a system designed for ultimate throttle performance.

Complete Kits, Built for Your Bike

Motion Pro offers complete throttle kit pairings to replace or upgrade your motorcycle's throttle system. Available kits include an ATV twist throttle conversion kit—a popular upgrade for riders who prefer twist-grip input over the stock thumb throttle—as well as early-model V-twin throttle kit assemblies. Each kit is engineered with vehicle-specific cables, cable boots to keep out dirt and dust, and billet aluminum inline cable adjusters to ease installation and fine-tuning. Whether you ride a sportbike, a motocrosser, an ATV, or an American V-twin, Motion Pro has a throttle kit built for your machine.
