These are much taller and longer than the average kids dirt bike and aimed at the racer or faster rider. These bikes have a 17 inch front wheel and a 14 inch rear wheel.
The Stomp 140 big wheel 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 Z3-140 big wheel 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.
