Description
2026 Stomp Z3-140 Pit Bike – Quick Overview
Best for: confident riders progressing onto a powerful 140cc manual pit bike.
Engine: oil-cooled YX140 with Z40 race cam.
Power: 8.2kW at 8,000 RPM.
Gearbox: 4-speed manual, N-1-2-3-4.
Wheels: 14-inch front / 12-inch rear with SDG hubs.
Seat height: 820mm.
Why riders choose it: strong 140cc performance, oil cooling, hydraulic disc brakes and a proven manual pit bike layout.
Our view: a serious step-up pit bike for riders wanting capable 140cc performance without moving to the more race-focused Z3R-140.
The 2026 Stomp Z3-140 is a capable 140cc manual pit bike built for confident riders who want strong petrol performance, proper clutch control and a dependable off-road setup.
Powered by an oil-cooled YX140 engine with a Z40 race cam, the Z3-140 produces 8.2kW at 8,000 RPM and 10.2Nm of torque at 7,500 RPM.
Its four-speed manual gearbox, lightweight steel spine frame, 14/12-inch wheel setup and hydraulic disc brakes make it a strong choice for riders progressing from smaller or less powerful pit bikes.
With an 820mm seat height, upgraded PRO footpegs, alloy fat handlebars and adjustable rear shock preload, the Z3-140 delivers a substantial step up in capability while retaining a straightforward, familiar pit bike layout.
For riders wanting an even more race-focused chassis and suspension package, the Stomp Z3R-140 Race sits above the standard model in the range.
My Take as a British MX Rider
The standard Z3-140 is a really sensible option for someone who wants a proper 140cc pit bike without necessarily needing the full race-focused package of the Z3R.
The YX140 engine with Z40 race cam gives it plenty of usable performance, and the four-speed manual gearbox makes it a great bike for developing clutch control, gear selection and riding technique.
I particularly like the combination of 14/12-inch wheels, hydraulic brakes and an 820mm seat height. It's a capable setup for riders who are already comfortable on smaller pit bikes and want something more substantial.
It doesn't have the same chassis and suspension specification as the Z3R Race, but not every rider needs that additional equipment.
If you're confident riding a manual pit bike and want strong 140cc performance for recreational off-road riding, the standard Z3-140 is a very good option.
