F43 CMX

THE WORLD’S BEST COMPACT
E-MOTO FORK. PERIOD.

An oversized, race-built F43 chassis paired with our CMX-tuned closed cartridge damper — built for elite control, razor-sharp handling, and unreal front-end confidence. This is the strongest, most durable, highest performance fork available.

You need to ride it to believe it.
It’s that good.

BIKE FITMENT:

  • E RIDE PRO SR

Note: This fork also fits the E Ride Pro SS 3.0, it will feel quite a bit Stiffer on the SS 3.0 due to having heavier spring rates for a heavier weight bike. Please compare Spring rates to the E Ride Pro SS 3.0 CMX Offering
