Moturo Shock Absorber 270mm FastAce BDA51AR for Pocket Bike and Dirt Bike

The Moturo 270mm FastAce BDA51AR shock absorber for your dirt bike and pocket bike — the component that absorbs every jump and pothole. 270 mm eye-to-eye distance, 250 LBS spring rate, ready to install.

The shock absorber works between the swingarm and the frame, soaking up impacts from the rear axle. Eye-to-eye distance 270 mm, spring diameter 68 mm, mounting hole diameter 19.6 mm, spring rate 250 LBS/IN. Spring preload adjustable via dial, gas pressure separately adjustable — for fine-tuning to rider weight and track conditions.

Universal size for dirt bikes and pocket bikes. Before ordering, measure the eye-to-eye distance and mounting hole diameter on your bike; the 270 mm is measured center-to-center.

Replacement takes about half an hour with a hex key set and socket wrench for the mounting nuts.

Frequently Asked Questions

Does the shock fit every pocket bike?
No, compare the 270 mm eye-to-eye distance and 19.6 mm mounting hole diameter on your bike before ordering.

The adjustment dial on the spring changes the preload — counter-clockwise for softer, clockwise for harder.

Do I need a registration?
For pure off-road bikes, no. For road-legal vehicles, check ABE/registration requirements before installation.
