saw an official Triumph power / torque graph today at

Shows 1600 and BB kitted curves, as a downloadable pdf - but sorry I don't know how to put it on here!
After my second test ride up some tight hill roads yesterday I'm still very impressed. Only problem was the back suspension kicking my back over sharp bumps - couldn't tell how much the pre-load was wound up but it was the front edge of the pillion pad that was the problem, as I found the forward footrests pushed me back against this fairly hard step. Easily sorted, as I'll need the dualseat anyway.
