Cylinder with piston APRILIA SR 80cc 47mm

APRILIA SR cylinder with piston, bore 47 mm. On the side of the body – a spigot for the coolant hose, so this is a cylinder for a liquid-cooled engine, even though the name does not say so.

• The set shows: cylinder, piston, gudgeon pin, two pin circlips, two piston rings, side flange gasket, cylinder base gasket, a red silicone ring with four ears and a large black sealing ring
• The photo marks: cylinder bore Ø 47 mm, the stud holes set out at 50 × 48 mm, total cylinder height with the lower centring collar – 88 mm
• Side flange: the bore is marked in the photo as Ø 22 mm, two bolts 48 mm apart, a partition is visible in the bore. Whether this is the intake or the exhaust side, the manufacturer did not mark on the photo
• Overall dimensions in the photo: from the side 120 mm (this measurement includes the coolant spigot too), from the top 133 mm (the side flange is included too); neither of them is the width of the cylinder body
• The photo marks: piston Ø 47 mm and 50 mm high, gudgeon pin bore Ø 10 mm; ring grooves – two
• The name states 80 cm³, but the photo marks only the bore – Ø 47 mm. We do not calculate the displacement from the bore: that also needs the stroke, and the manufacturer did not state it
• The head is not in the set – you fit your own
• The separate "Piston with rings 47,00mm 13mm pin" in the list does not fit here: that piston's pin is 13 mm, while this one's is 10 mm
• The list also has "Engine gasket set APRILIA DERBI 2006 70cc LC" – whether it fits this exact cylinder, the manufacturer did not state
• Wear is visible to the naked eye: longitudinal scratches on the cylinder wall, a polished-shiny piston skirt, and a ring that rocks loosely in its groove – then the whole group is replaced at once

To be straight with you. Which specific APRILIA SR models and years this cylinder fits, the manufacturer did not state, and we do not guess – write us your model and year. Before ordering, unscrew the spark plug and use a caliper to measure your old cylinder's bore, pin thickness and the distance between the studs – we will check it before you order.
