Baja Dirt Runner 70 (DR70) 70cc Dirt Bike Parts

This page carries replacement parts for the Baja Dirt Runner 70 (DR70), a 70cc dirt bike from Baja Motorsports. We stock carburetors, ignition coils, air filters, spark plugs, throttle cables and grips, 420 chains, transmission shafts, gearshift parts, brake shoes, tires and inner tubes, seats, and fenders.

The DR70 rolls on 2.50-14 and 3.00-12 tires, and we carry knobby tires and inner tubes in both sizes. The chain is 420, sold in 9 ft. lengths with a master link. The carburetor also fits the Dirt Runner DR49 and Warrior WR49, and the 29" throttle cable is shared with the DR50, DR90, DR125, DR150, and X250. We carry rear brake shoes in 79 mm and 105 mm sizes, so measure your old shoes first. Check the frame or engine label for your model number. Can't find your part?
