Supermoto Parts Fitment Guide: Razor, Tuttio, Yozma & ETM RTR

Riders ask us the same question in different ways: "will this fit my bike?" Here's a straight answer, organized by part category, for every model we build for: Razor MX500, MX650, and SX500, the Tuttio Soleil 01, the Yozma, and the ETM RTR (including RTR Lite and Rizzler).

Wheels

Our 12" Supermoto Wheel Set is a direct bolt-on fit for the Razor MX650, Tuttio, and Yozma. Each set includes both wheels, two 190mm brake discs, a sprocket (420-48T or 420-60T), and all mounting hardware, so you're not piecing together parts from three different listings.

Brakes

For the ETM RTR, we build the only Ultra Bee brake kits on the market: a front kit, a rear kit, and a dual-caliper footbrake kit, all pre-bled and bolt-on with custom machined aluminum mounts. They work across dirt wheels, big wheels, and supermoto wheels.

For Tuttio and Yozma, our Ultra Bee rear brake kit pairs an OEM-style Ultra Bee caliper with an ER Moto mounting bracket, pre-bled and ready to install.

General Razor, Tuttio, and Yozma brake kits and hardware are grouped in our Brakes collection.

Shiftlocks

The Razor Shiftlock and Double Sided Razor Shiftlock are built for Razor MX500, MX650, and SX500. For the ETM RTR, our ETM RTR Shiftlock is designed and manufactured by ER Moto and mounts with stock or titanium-style bolts, shiftlock peg included.

Titanium Hardware

Razor riders can upgrade bar clamp, gas tank, and triple tree bolts individually or as our Titanium Bolt Upgrade Kit. Tuttio owners (2024, 2025, and 2026 models) can go further with the full Tuttio Titanium Bolt Set, covering bar clamp, triple tree, controller mounts, motor cover, bash guard, fork guard, bar pad, chain guide, and brake line bolts in one kit.

Protection: Mud Guards, Flaps & Battery Guards

Our V2.0 and V2.1 Razor Mud Guards, mud flap, battery guards (MX650/500 and SX500 versions), swing arm plugs, and Fardriver controller mounts are all built specifically for Razor MX500, MX650, and SX500 frames. See the full lineup in our Fenders & Mud Guards collection, or grab several at once in the Razor Protection Bundle.

Throttles & Switches

The Tuttio Soleil 01 gets a premium Surron-style throttle upgrade (manual wiring required). The ETM RTR, RTR Lite, and Rizzler get a plug-and-play metal Surron throttle paired with a 3-speed switch, no cutting or wire removal needed. Razor riders can add our plug-and-play 3-Speed Switch or Volt Meter Key Switch, both compatible with FarDriver-equipped MX500, MX650, and SX500 builds.

Lighting & Accessories

Our battery-powered baja lights, rock lights, and horn kits are universal, they fit any bike, no wiring into your electrical system required. See the full range in Baja Lights and Throttles, Horns & Switches.

Still Not Sure What Fits?

If your bike is a variant we haven't listed by name, message us with your model before you order; we're happy to confirm fitment first. It's faster than guessing, and it means you only order once.
