Hero Genuine Duet / Maestro / Pleasure / Xoom Piston Kit O/S 0.50

Rebuild the engine top-end with the Hero Genuine Piston Kit O/S 0.50 K13131KTPE900S2S. This genuine Hero oversize piston kit is intended for compatible Hero scooter engine applications where the cylinder has been rebored or matched for a 0.50 oversize piston.

The part is commonly searched by mechanics and scooter owners as a piston kit, oversize piston kit, 0.50 piston kit, O/S piston, engine piston set, bore piston kit, or scooter piston kit. Choosing the correct genuine Hero kit helps maintain proper piston fit, compression, oil control, engine reliability, and long-term performance compared to generic or incorrectly sized piston kits.

This SKU should be matched carefully with the engine condition, bore size, old piston size, and vehicle variant before ordering. Oversize piston kits are not direct replacements for standard-size pistons unless the cylinder bore has been prepared for the matching oversize.

No wider compatibility is being added for Destini, Pleasure Plus, Maestro Edge 125, Activa, Jupiter, Access, or any other scooter unless the same part number and piston oversize requirement are confirmed for that vehicle.

Fitment Note / Return Prevention Note

Before ordering, match the piston kit with part number K13131KTPE900S2S / K13131-KTP-E900S2S, the scooter model/variant, engine generation, bore size, piston oversize requirement, ring specification, and cylinder condition.

Do not order this as a standard piston kit. This is a 0.50 oversize piston kit. Incorrect piston size can cause compression loss, seizure, piston slap, smoke, oil consumption, or serious engine damage.

It can help when the issue is caused by piston/cylinder wear and the bore is correctly prepared. If valves, guides, seals, gasket, timing, or crankcase issues exist, those must also be checked.

Q8. How can I confirm fitment before ordering?
Match the part number, vehicle model, engine generation, current piston size, cylinder bore measurement, and required oversize. Mechanic/VIN-based confirmation is recommended.
