Grasstrack Racing

Grasstrack racing is a form of track racing which typically, in its current form, takes place on a flat track consisting of two straights and two bends usually constructed in a field. It is one of the oldest types of motorcycle sports in the UK with the first meetings having taken place in the 1920s. In the modern era, it is generally similar to Speedway with races usually taking place over 4 laps from a standing start. Unlike Speedway, which has 4 riders per race, Grasstrack racing can have many riders in each heat and the circuit is normally longer allowing higher speeds. Grasstrack has three solo classes, 250cc, 350cc and 500cc together with three sidecar classes; left-handed 500cc and 1000cc (turning left) and right-handed 1000cc (turning right).

Grasstrack motorcycles look quite similar to Speedway machines but there are different engine capacity limits for each class. In the United Kingdom there are classes for 250cc (normally 2 stroke engines), 350cc and 500cc bikes (usually 4-stroke engines). Unlike Speedway bikes which have no gears, Grasstrack bikes usually have a 2 speed gearbox. Both Speedway and Grasstrack bikes have no brakes. The only other main difference is that speedway bikes have no rear suspension and are shorter in length, usually by around 10–12 inches. There is also a class called Pre-75. These are bikes that have been made before 1975. The three classes in Pre-75, are 250, 350 and 500cc.

GT140 Grasstrack racing is one of the fastest-growing classes in UK grasstrack motorcycle racing, created to provide an affordable and exciting entry point into the sport. The class uses lightweight race bikes powered by 140 cc pit-bike engines, typically running on petrol, mounted in purpose-built grasstrack frames. Designed to keep costs down while maintaining competitive racing, GT140 bikes are simpler and cheaper to run than traditional larger-capacity grasstrack machines. Races take place on oval grass tracks with standing starts and multiple riders battling over several laps, producing close, action-packed racing. Thanks to its accessibility, strong grids, and thrilling on-track battles, GT140 has quickly become a popular class for both new riders and experienced racers looking for competitive, budget-friendly motorsport.
