Motocross bikes

Motorcross bikes are lightweight bikes (80kg – 95 kg) built for speed and manageability. For this reason the bike engine may well still be a two stroke although four strokes are now quite common. Engine capacity falls between 125cc and 600cc with the bigger engines being more trail and enduro bikes than true motocross. The bikes are single cylinder because of the need for lots of torque at low revs.

Wheel rims are large and suspension travel long to soak up the rough terrain. Bikes seats are small and uncomfortable as they are mainly ridden standing up or for short periods of time. Fuel tanks are also very small at between 7 and 8 litres.
