Stomp Z3-140 Big Wheel Pit Bike – Quick Overview
Best for: taller riders wanting serious 140cc performance with a bigger, more stable feel.
Engine: SR140C engine with Z40 race cam.
Power: approx. 14hp at the rear wheel.
Wheels: 17 inch front / 14 inch rear SDG steel wheels.
Why riders choose it: big wheel stability, race-tuned 140cc power, upgraded suspension and top-end Stomp performance.
Our view: the top Stomp pit bike choice for taller or more experienced riders wanting a full-size feel.
The Stomp Z3-140 Big Wheel takes the serious performance of the standard Z3-140 and adds a bigger 17/14 wheel setup for more height, more stability and a more full-size motocross feel.
With the same SR140C race engine, Z40 race cam, SDG2 heavy-duty chassis and upgraded suspension package, the Big Wheel version is designed for taller riders or anyone wanting better rollover and more confidence at speed.
This is the top end of the Stomp pit bike range — a race-ready 140cc manual pit bike with a bigger stance and more planted feel than standard 14/12 models.
My Take as a British MX Rider
The Z3-140 Big Wheel is the one I’d look at if the rider wants the punch of a pit bike but needs more height and stability.
The 17/14 wheel setup changes the way the bike feels. It rolls over bumps better, feels more planted at speed and suits taller riders far better than a standard small-wheel pit bike.
If you want the top Stomp 140cc package with a more full-size feel, the Z3-140 Big Wheel is the one to choose.
