comfort , rather than an extreme race , low position . The seat is not high , but not that low either at 815mm from the deck .

The engine produces 100hp at 10,500rpm and 67Nm of torque at 8500rpm , but impressively 80 % of that torque figure is readily available from only 4000rpm . The cylinders are fed by two 48mm throttle bodies . The compression ratio is a healthy 13.5:1 and the sixspeed gearbox is tickled as standard by a quick-shifter . The engine is liquid cooled , as is the oil , via a liquid-cooled oil heat exchanger .
