congratulations. restricted Sv650 should be perfect, was for me after passing on a honda cbr125, although it did feel very wide the first time i got on it, I rode it back 50 miles from purchase as it was already restricted from previous owner. Cbr125's look like bicycles to me now. i'm 5'8/9 (time of day dependant haha) and 11st for what its worth + looking forward to july when the 33bhp kit comes off*
*another plus of the restriction, being that after two years it'll be like having a new bike to play with. Stopped me looking around at larger bikes etc
