STOMP Z3 140 Z-40 Race Report

"STOMP Z3 140 2025 Featuring the Exclusive Z-40 race camshaft factory equipped engine, Beefed up Crank Cases and Needle Roller Gearbox Bearings. The Z-40 Race Camshaft is only fitted to Stomp and WPB engined bikes, no other UK Pitbike engine manufacturer fits this legendary camshaft to their engines and the 17Hp at rear wheel in Stock form is plenty to scare the Pants off the unsuspecting! "

The 2025 Z3-140 has been Upgraded to Now Include Polished Allow Hubs and

HSK Racing Brakes front and rear and Pro Footpegs. The New Detroit Plastics add something new

to the Race scene and are Unique to Stomp

The Z3-140 still boasts the ‘exclusive to Stomp’ SR140C/Z-40 cam engine. Stomp buy in the YX140 and then fettle the engine with stiffened valve springs & a high lift race cam (known as the z-40 cam). The result is 2 HP more than any other YX140 engine on the market. It might not be quite Zhongshen 155 territory, but its most of the way there and significantly cheaper to install than the Z155 which would see retail prices creeping over the £1200 mark. If you look after the Stomp 140 Z-40, it will prove a very reliable and cheap engine to run.

Stomp still retain the big wheel version (17/14) for those more into field hacking who need that extra stability in muddy conditions.
