For MX500 • SX500 • MX650
Pre-Wired. Pre-Tuned. The Final Boss of Razor Upgrade Kits.
This is it — the largest, hardest-hitting, most extreme Razor conversion Momentum Watts has ever built. The 15,840W Kit turns your Razor into a 72V missile with brutal acceleration, insane torque delivery, and the type of power that makes every other Razor feel like a toy.
Just like all Momentum Watts systems, this monster arrives fully pre-wired, pre-tuned, loomed, labeled, and ready to install, complete with the correct chain and sprocket. No wiring. No coding. No stress. Just pure, unapologetic watts.
If you want the strongest kit we offer — the one that separates the casual riders from the committed thrill-seekers — this is the one.
