The Z3R-140 is the ultimate budget race bike from the Stomp stable. This bike boasts the upgraded SDG2 frame and the Detroit plastics, as well as the suspension from its podium-winning predecessor. The best 140 pit bike out there.

The Z3R-140 still boasts the ‘exclusive to Stomp’ SR140C Z40 cam engine. Stomp buy in the YX140 and then fettle the engine with stiffened valve springs & a high lift race cam (known as the Z40 cam). The result is 2hp more than any other YX140 engine on the market.
