Athena piston kits and drive belts

Athena Piston Kits for Aprilia RS 125 etc.

Our latest Athena delivery saw the arrival of forged piston kits for RS 125 and AF1 125 models using Rotax 122 / 123 engines. With both A and C grade pistons available the A is 53.95mm and C 53.97mm. The choice is there for older barrels that may be slightly worn requiring a piston kit that’s a fraction bigger. We expect these will be very popular amongst the British Superteen racing classes as they're cheaper and much stronger than the original.

A: 53.95mm – AD/S4F05400015A - £91.00
C: 53.97mm – AD/S4F05400015C - £91.00

Athena 170cc cylinder kit for Honda CBR 125

The Athena 170cc kits are now in stock for CBR 125 models. We are stocking two kits, one for injection models and one for carburettor models. Both kits feature aluminium nickel-carbide barrels and cast-lite pistons. The kit for injection models comes with a new ECU that changes the rpm curve bringing power in at 6000 rpm right through to 13000 rpm. Peak power on the dyno comes in at 16.8 hp on injection models, unfortunately we don't have any information for carburettor models as of yet but expect similar gains but not as low down the rev range. These kits are one of the very few parts for CBR 125's that make any real power increases. Spare pistons and gasket sets are also in stock.

Athena 183cc cylinder kit for Yamaha YZF R125 etc.

Now in stock from Athena are the long awaited 183cc cylinder kits for Yamaha 125cc 4T learner legals. They fit Yamaha YZF R125’s and WR125’s, both great looking bikes but both lacking in the power they deserve. The kit takes the capacity up to 183cc with the new aluminium nickel-carbide plated barrel and cast-lite piston. Also included in the kit is a new ECU that remaps the rpm curve bringing power straight in at 5000 rpm and holding out right through to 10500 rpm. The dyno shows a peak power of 17.1 hp at just under 9000 rpm.

Grab yours while you can as these have been long awaited in the UK so we're expecting they'll go pretty quick being the only part available for these bikes that will give any significant gains. We also now stock pistons and top end gasket sets for these kits, here are the product codes and links:
