Cylinder with piston for A50 bicycle engine

A50 cylinder with piston for a bicycle engine. In the box: cylinder, piston, gudgeon pin, two rings and one gasket; no circlips in the photo.

• The kit shows: cylinder, piston with a flat crown, gudgeon pin, two rings and one brown paper gasket
• The body has cooling fins, no hose spigot — air-cooled
• The manufacturer's drawing marks: from the top 42 mm and 40 mm between the holes and 59 mm; from the side 83,50 mm and 92 mm, 15 mm, 22,50 mm and 32 mm; from the other side 16 mm, 25 mm, 40 mm and 70 mm
• Piston Ø 40 mm and 46 mm tall, pin bore 10 mm; pin 32,30 mm long
• The cylinder bore is not marked in the drawing — the only known figure is the piston's 40 mm diameter, so measure your own bore
• The listing also has "Cylinder with piston for A80 bicycle engine" — a larger displacement in the same line; the cylinder heads for both are separate items, A50 and A80
• Wear is visible to the naked eye: longitudinal scoring on the cylinder wall, a polished piston skirt, or a ring that rocks loosely in its groove — then the whole group is replaced at once
• Supplier code WI AWRC0021 — state it again when ordering

To be straight with you: which exact models and years this cylinder fits, the manufacturer did not state, and we do not guess — write us your machine or send a photo of the old part. Before ordering, remove the spark plug and use a caliper to measure the old cylinder's bore, the pin thickness and the distance between the studs — we will check before you order.
