I think that maybe there is some confusion as to the Hp data that I posted. These are rear wheel dyno numbers. The 69hp for the thruxton and the 70hp for the sporty that you are reffering to are the advertised stock numbers at the crank. You can usually deduct 15 to 20% from the advertised crank hp. for power train losses. The hp.& torque numbers at the back wheel are best used for comparisons.
