The KMXR140 Pit Bike

The CRF70 bikes are bigger than the equivalent CRF50 range by around 10cm in seat height, making them much more comfortable for adults and teens when riding “in the seat”.

The KMXR140 Pit Bike comes in a 14/12 small-wheeled version with a seat height of 82cm, and a 17/14 big-wheeled version which has a seat height of 86cm.

THE KMXR140 PIT BIKE - 140CC 4-STROKE ENGINE THE KMXR140 PIT BIKE - REINFORCED BLACK SDG HUBS

140cc 4-stroke engine

It features a YX Motorsports 140cc 4-stroke oil cooled engine. For pure performance reasons, the gearbox has been fitted with a racing pattern sequence. Neutral at the bottom, then 1-2-3-4 gears up. And for quick restarts the engine is kick-in-gear, so can be started in gear rather than shifting to find neutral.

Reinforced Black SDG Hubs

Reinforced black SDG Hubs, have been laced with stainless steel chrome spokes, anodised silver spoke nipples and strong reinforced powder coated black steel rims. Super chunky block pattern knobbly motocross tyres offer awesome off-road grip. A strong setup right there.
