These bikes are based on the Stomp z3 140 but have an alloy swinging arm and a shock with fully adjustable compression and rebound damping. The upside down fork also has adjustable damping.
These are much taller and longer than the average kids dirt bike and aimed at the racer or faster rider. These bikes have a 14 inch front wheel and a 12 inch rear wheel.
The Stomp Z3 R 140 has a new chassis moving to a spine frame. This allows for increased rigidity and thus stability at high speed, but more importantly allows space for the extra-long rear shock & the subsequent huge swing arm travel. Stomp learned in 2014 that in order to match & then beat Bucci lap times, they needed more suspension travel, and the all-new chassis design is a direct result of that experience. The Z3-R-140 still boasts the ‘exclusive to Stomp’ SR140C/Z-40 cam engine. Stomp buy in the YX140 and then fettle the engine with stiffened valve springs & a high lift race cam (known as the z-40 cam). The result is 2 HP more than any other YX140 engine on the market. If you look after the SR140C, it will prove a very reliable and cheap engine to run. For an MX bike for sale near Glasgow you will be hard pressed to beat AAA Motorcycles who have been a motorcycle dealer in Paisley for too many years than we care to remember.
