 STOMP Z2 140 z40 Race Report  

"STOMP Z2 140 2016 Featuring the Exclusive z40 race camshaft factory equipped engine, Beefed up Crank Cases and Needle Roller Gearbox Bearings. The Z40 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 2016 Z2-140 has a completely BRAND-NEW chassis moving from a single spine to a twin beam construction. This allows for increased rigidity and thus stability at high speed, but more importantly allows space for the extra-long rear shock & the subsequent huge swing arm travel. Stomp learned in 2014 that in order to match & then beat Bucci lap times, they needed more suspension travel, and the all-new chassis design is a direct result of that experience.

The Z2-140 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 £1000 mark. If you look after the SR140C, 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.

Stomp Z2-140 Review

"Price vs spec? Stomps predecessor, the Z-140 was the best-selling pit bike 
in the UK for 4 years. The Z2-140 now takes Stomps winning formula & punts it 
into the stratosphere, pretty much annihilating anything else on the market 
in the same price bracket. It’s £6,000 Bucci performance for under a grand??? 
How the **** have they done this? It’s simple, by racing Bucci’s on the track Stomp 
have stepped up the game & proven yet again you do not need to spend inordinate 
amounts of money to have a seriously FAST world-class pit bike. 
The results on the track tell the full story, the Z2-140 will give more bang 
for your buck than any other machine out there and if you are thinking 
about taking it straight to the track, why not take a look at 
the Z2R cus that monster is race ready out of the crate and 
a full race replica of Troy Becks Podium winning machine."
