Warp 9 Emoto Rotors - Rear

The rear half of Warp 9's e-moto rotor range, from a 203mm fixed disc up to a 300mm floater, with fixed and floating options depending on diameter. A larger rear rotor mostly buys consistency on long descents rather than outright stopping power, since the rear tire runs out of grip first.

Rotors are listed separately for stock hubs and for Warp 9 hubs, so match the hub before matching the size. Going up in diameter needs a caliper adapter to reposition the caliper, and the rear caliper bracket is not interchangeable with the front. Check chain and swingarm clearance on the larger sizes, then bed the new rotor and pads in gradually.
