The Thumpstar 140 is aggressive, loud and on point. You can leave £10,000 Surrons on charge with their owner’s ears bleeding with a simple blip of the throttle, braaaaaap! A big wheel pit bike (17/14) that stays true to its heritage whilst progressing the sport in-line with what our customers demand. Sharp cutting-edge design, clean lines, tasteful livery and a soundtrack from our high-performance exhaust system that will make your knees go weak. Only the finest components are selected for our bikes. The engine-tune and chassis-geometry are born of our extensive racing knowledge and together, these attributes form what we consider to be the finest 140 cc pit bike money can buy. Be careful, the secret is already out.
