havent done it myself as i have a 910R tricked up, i'd say you could expect the following.
brakes awesome brembo monobloks!
slipper clutch great for track use,
not much more top end power but a decent improvement on bottom end.
suspension will be a little bity more compliable, wheels much lighter and therefore easier to chuck around.
thats about it, if you love your 910S you will love the 1078RR but dont expect it to be totally different as it wont be.
I just bought a 1078rr. I was choosing between the ducati streetfighter and this bike. The duc was fitted with slipons + new mapping. It was no competition - the 1078rr just had this fantastic feel about it. I think only riding one will I person ever understand what it is about brutale. I've had 10 bikes over the last 9 years including RSVR factory, KTM superduke, bandit 1250 and CBR900 and nothing comes close to the way this bike feels. The I road the streetfighter second and it felt docile compared to the 1078rr.
I looking forward to a long relationship with my new love!
