Motion Pro Rev3 Throttle Kit – Honda Grom 125

Transform your Honda Grom 125's throttle response with the Motion Pro Rev3 Variable Throttle Kit — one of the smoothest, most adjustable throttle systems available. Swap between interchangeable reels in minutes to dial in exactly the throttle rate that matches your riding style, whether you're carving canyons or commuting. The slim, compact housing keeps your bars clean and clutter-free, and the PTFE-lined cables deliver buttery-smooth operation ride after ride.

Designed as a direct replacement for the Honda Grom 125, the Rev3 kit replaces your throttle control entirely. For a cleaner look, pair it with a slim control switch (sold separately — see related items for plug-and-play options).
