  1. Derrick L. – Austin, TX

    Absolutely love this transmission. It’s like putting a performance gearbox in a race car. Precise, responsive, and handles high RPMs with no problem. My only regret is not doing it sooner!

  2. Mike P. – Mobile, AL

    Performance is undeniably better, but it’s louder than I expected. Might be normal for this kind of build, but it caught me off guard. I’d recommend this to racers and aggressive riders—not necessarily the average weekend cruiser.

  3. Angela M. – Tampa, FL

    Super smooth shifts and improved torque handling make this a winner. No more clunky downshifts like the stock gearbox. If you’re looking to push your engine mods to the next level, this transmission is the missing piece.
