🏁 SIRRIS F43 CMX TUNE | 220 MM TRAVEL | E-Ride Pro SR ⚡

Oversized race built F43 chassis paired with the CMX tuned closed cartridge damper. Elite control, razor sharp handling and unreal front end confidence 🔥

The CMX Tune takes the same oversized, race proven F43 architecture Sirris build for full size e-motos and packages it in compact e-moto sizing for the E-Ride Pro SR. 220 mm of travel, a CMX tuned symmetrical closed cartridge damper and tool free compression adjusters so you can dial it in trackside with your fingers.

Ø43 mm oversized stanchions, hard anodised 7050 outer tubes and moto grade NOK seals with Daido bushings. This completely changes how the SR turns, brakes and lands.
