Aprillia brought out a very lightweight V-twin in the RX a few years back that was a bit of leading edge... The problem is the engine proved unreliable as they were sucking too much power out of it... Drop the power by 20% and it is likely the reliability of that platform would go up while still providing plenty of punch...
The 5.5 put out 61hp. 61 * .8 = 48.8, hardly impressive power output and the bike was ~310lbs.
