The Z3-160 sits towards the top of the pack as one of the more powerful pit bikes in our range. Packing serious performance from its ZS155 4-stroke engine and running on big 17/14 wheels, this is a bike built for experienced riders looking for maximum performance from a compact pit bike chassis.

Back in 2007, Stomp took the legendary YX140 engine and squeezed it into a pit bike named the SuperStomp 140. That combination of lightweight chassis and big performance helped put Stomp firmly on the map. The Z3-160 carries that same philosophy forward: lots of power, minimal unnecessary weight and maximum fun.

For 2026, the Z3-160 receives one of its biggest component and styling updates yet.

Up front, the bike now features Series 6 alloy variable-diameter handlebars together with new grips and new black upper and lower clamps. The result is a more premium cockpit with the aggressive factory look the Z3 deserves, finished with a new Stomp-logo bar pad cover.

A new lower-noise Power bomb exhaust system has also been introduced, complete with a Stomp identification plate, retaining the character of the big ZS155 engine while reducing unnecessary noise.

Elsewhere, the Z3-160 gains an updated rear brake, titanium-colour front brake, titanium-colour wheel hubs, black spokes and nipples and a titanium-finish engine bottom support. Together, these changes give the latest Z3 a much more cohesive factory finish.

Underneath the updates remains the lightweight single-backbone frame and cradle that makes the Z3 so nimble. Rather than chasing full-size MX dimensions and unnecessary weight, the Z3-160 stays true to what a serious pit bike should be: compact, responsive and ridiculously entertaining.

USD forks, a preload-adjustable rear shock and the larger 17/14 wheel combination complete a package designed to make full use of the ZS155 engine.

Aggressive visual cues, clean lines, distinctive Stomp graphics and nearly two decades of pit bike development come together in the latest Z3-160.

Turn up the volume and smell the petrol. BRAAAP!
