Stomp Z3-140 140cc Pit Bike – Quick Overview
Best for: riders stepping into serious 140cc pit bike performance.
Engine: SR140C engine with Z40 race cam.
Power: approx. 14hp at the rear wheel.
Wheels: 14 inch front / 12 inch rear SDG steel wheels.
Why riders choose it: race-tuned 140cc power, upgraded suspension, SDG2 chassis and full manual control.
Our view: a serious performance pit bike for riders ready to go beyond entry-level machines.
The Stomp Z3-140 is built for riders who are ready to step into proper 140cc pit bike performance. With a race-tuned SR140C engine, Z40 race cam, upgraded suspension and SDG2 heavy-duty cradle frame, it sits well above basic entry-level pit bikes.
Compared with smaller 110cc and 120cc models, the Z3-140 gives noticeably more power, sharper response and a much more planted feel when riding faster or tackling rougher terrain.
This is a serious manual pit bike for riders who want real performance for tracks, fields and harder off-road riding.
My Take as a British MX Rider
The Z3-140 is where the Stomp range starts to feel properly performance-focused.
The jump to a race-tuned 140cc engine, stronger chassis and piggyback shock makes a real difference once the rider is confident and starts pushing harder.
If the rider is ready for more power, stronger suspension and a more aggressive manual pit bike, the Z3-140 is the proper step up.
