STOMP 20 YEARS – BACK TO OUR ROOTS.
To celebrate 20 years of Stomp, we’ve gone back to where it all started — dominating the UK supermoto scene.
We’ve built a range of track-focused, off-the-shelf supermoto bikes, ready to race straight out the crate:
90cc – for the Bambino class
140cc – built for stock class racing
212cc – for open class or anyone who just wants to be the fastest guy on a track day
Every bike is properly kitted for the track:
- PMT racing slicks
- Class-specific performance engines
- DNM & Fastace suspension
- Full track prep: catch trays, crash bobbins, hand guards, breather systems
No messing around. No extra spend.
Just turn up and ride.
This range is built to be the perfect entry point into supermoto racing — with performance where it counts, at a price that keeps it accessible.
