I had a ride on a RSVR haga rep recently and to be honest I prefer my 749. I felt really on top of the aprillia rather than part of it which I get from the ducati. I didnt ride the bike for long so didnt really get time for the feel. So Im probably not worth listening to
One of my mates who rides and r1 has also been for a spin on both the duke and aprillia and he said the duke felt better, but that was on a 749 not 748.
tricky.
