I don't have a V7 or a BMW but I have a v65 and a big sport-touring bike (Breva1100)
and with the same rider, I can absolutely whoop myself in the twisties on the v65 over the breva...
doesnt matter that the breva has 40 more HP, stronger brakes, and wider tires.. rider confidence, lower weight, and familiarity get me there quicker on the little bike..
it's deff more fun to ride a slow bike fast than a fast bike slow
