Product Description

The Stomp FXJ 110 Semi is the perfect entry-level bike for field racers and back-yard thrashers. Simple to get to grips with but surprisingly fast, the semi-automatic 110cc 4-stroke engine packs a serious punch while keeping gear changes straightforward for riders making the move onto a bigger petrol pit bike.

Conceived and refined for fun, but capable of so much more, the FXJ features our proven in-house geometry and gains privileged access to our special-edition engines, built specifically for Stomp.

For 2026, we’ve given the FXJ a fresh round of upgrades. New grips improve the all-important rider contact points, while titanium-colour front and rear brakes, titanium-colour wheel hubs and a titanium-finish engine bottom support give the bike a much sharper factory look. The wheels are finished with new black spokes and nipples, completing the updated styling.

Built by one of the biggest motorcycle factories in the world using quality components, robot welding, dedicated test tracks and highly trained staff who are proud to build Stomp.

All our bikes are test ridden prior to being broken down for shipping, so you know you are getting a properly developed bike from a reputable brand with full spares backup for years to come.

At Stomp, we have been refining our pit bikes for almost 20 years. The latest FXJ 110 Semi takes everything we’ve learned and adds a fresh factory finish to one of the most accessible bikes in the Stomp range.
