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:
