Mitaka 125cc Cylinder and Piston Kit for '99-'10 RS125

This cylinder kit comes in at a whopping $800 under the price of the OEM Aprilia parts, but suffers no loss of reliability or quality despite the difference in price. In fact, AF1 Racing's own RS125 endurance racer has logged 2 full seasons of endurance racing on a standard Mitaka cylinder.

This kit includes:

cylinder
piston
piston rings
piston wristpin
piston wristpin bearing
piston pin clips
3 thicknesses of base gaskets
exhaust manifold gasket
intake manifold gasket
power valve gasket
inner head O-ring
outer head O-ring.

 

This kit does NOT include the cylinder head, or the water jacket cover.

This cylinder is an exact pattern copy of the Aprilia/Rotax stock cylinder. Its displacement, port positions, and native squish figures are all identical to OEM.

Retail for this same collection of parts if ordered direct from Aprilia is over $1400

The piston rings supplied are directional. You must install them with the letter "R" facing the sky.

Piston supplied is 53.97mm.
