Rotax 122 Mitaka 140cc big bore kit (fits RS RX SX MX Tuono 125)

£265.00

Product information

New Mitaka 140cc big bore kit to fit the Rotax 122 engine as fitted to loads of Aprilia 125s.

Kit includes-

barrel
piston
Rikon rings (Japanese)
3 x base gaskets (different thicknesses to help set squish and compression ratio)
head o-ring
water jacket o-ring
RAVE gasket and seal
gudgeon pin and circlips

The standard RS125 cylinder head (or aftermarket equivalent) is used.

Small end bearing not included.

We'd recommend fitting this kit to a fresh or low mileage bottom end as the increase in power and torque could cause premature failure of a worn crank and/or main bearings.

We also offer the option of a clean up/blueprint of the barrel before it is sent to remove any casting marks that may impede mixture flow.

Please note: there is an additional postage cost for these items due to the size and weight of the packaging - EU postage is £28.99 and the rest of the World is £49.99. UK postage is not affected.
