Product Description

Back in 2007 Stomp were the first to take the legendary YX140 engine and squeeze it into a pit bike named “SuperStomp 140”. This absolute killer combination of an aftermarket frame and bonkers engine put Stomp firmly on the map. Ever since, Stomp fans and customers have been going crazy for their Pit Bikes, making Stomp a globally recognised brand. The Z3-140 continues this epic motorcycle brand legacy. It is still powered by that immense 4-stroke thumping single cylinder YX140. The engine is ‘exclusive to Stomp’ being the SR140C Z40 model producing 2hp more than any other YX140 engine on the market. If you look after the SR140C, it will prove a very reliable and affordable engine to run.

The chassis is a lightweight single backbone frame with cradle to keep the bikes mass down. This makes it faster and nimbler than many other brands focusing on MX looks at the cost of performance. The suspension is simple yet effective with plenty of travel. There’s even scope to upgrade the rear shock should you feel the need to start hitting some heavier jumps. The USD Forks and triple clamps complete the look while based on your personal preference the bike is available with two wheel options, 14/12 or 17/14 (big wheel).

The Z3-140 follows the trend for larger Pit Bikes, more space on the bike, yet still a lot of fun to throw around. Aggressive visual cues, clean lines and highly distinctive factory graphics complete a well-balanced looking bike that’s tasteful yet means business.

This is a true Surron killer for a fraction of the money, so TURN UP THE VOLUME AND SMELL THE PETROL BRAAAP
