The 2015 Z2R-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 ay 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 Z2R-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 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. This is of course the ‘R’ model which means you get fully adjustable suspension & quality MX spec tyres making it ready to race out of the crate.
