R6 06-09

This example is a Supersport Tune' to comply with the British Supersort series regulations. The FW Developments spec YZF-R6 was developed for the Raceways Yamaha team in the British Supersport championship.

The complete engine was stripped to the crankcases, all bearings were measured and re-sized. The cylinder head was CNC ported and valve seats cut. FWD spec camshafts were fitted and shimmed to suit.

The end result is a 600cc machine, producing between 135 - 140bhp.
