Whether you're a racer looking for a quick-turn throttle response or a street commuter wanting to tame a twitchy throttle for smoother riding, the Motion Pro Rev2 Variable Throttle Response Kit is your answer. The kit includes an easy to install throttle assembly, throttle tube, grips, and cables that replace the stock counterparts. You'll also receive 4 standard reels and 1 progressive reel, each offering different throttle response characteristics. The high-quality Motion Pro black vinyl cables are specifically designed for the Yamaha R3, making installation as easy as possible, while the Rev2 Throttle Assembly has been engineered to make reel swaps a fast and easy process. Motion Pro purposefully designed each element of the system to withstand the high demands and intense conditions of racing, producing only high-quality components trusted by professional racers across the globe.

Standard Reels

  • 4 reels to choose from: 35mm (black), 40mm (blue), 45mm (red), and 50mm (yellow)
  • Unique reel design enables easy reel changes without the need to readjust throttle cables
  • Heavy-duty nylon composite material with high-wall design keeps cable secure and provides smooth operation
  • Smaller reels provide slower throttle response / larger reels provide faster throttle response

RR Cam (Progressive) Reel

  • Sportbike oriented cam profile performs like a slow throttle to 40% opening, then progressively changes to fast profile from 70% to 100% throttle
  • Enables greater control at lower throttle openings while providing faster response at higher throttle openings

Every Motion Pro Rev2 Variable Rate Throttle Kit comes with the 5 throttle reels described above, enabling you to install the right reel for your style or riding conditions. But how do you know which one to choose? It's pretty simple actually. The reel size determines how much wrist twist (or throttle input) is required to fully open the throttle bodies on the Yamaha R3. The larger the reel, the shorter the twist, and vise versa.

Each throttle reel will change the twist by about 10 degrees. An example would be if a stock throttle of 40mm has a full twist of 90 degrees, or 1/4 turn, the 45mm Motion Pro Rev2 Reel will reduce the required twist to 80 degrees, and the 50mm Reel will reduce the twist to 70 degrees. This enables a much faster throttle response and requires less input to reach 100% throttle opening. On the other hand, going with a smaller than stock reel size by installing the 35mm Rev2 Reel will increase the throttle twist to 100 degrees, increasing the amount of input required to reach a fully open throttle.

Now that covers the standard Motion Pro Throttle Reels, but you'll also receive our personal favorite option, the "RR Cam Reel" which is easily identifiable by its orange color. This is a progressive throttle reel that combines the best of all the standard reels. It acts as a slower throttle from 0-40% open, then progressively changes to a faster throttle for the 70-100% open range. This progressive design enables you to have more control when riding at lower throttle open speeds, such as around the paddock or start and stop traffic, while still providing that race bike response in the upper throttle range. This is ideal for both street and track riders alike.
