Dam i need to get 1 of those little screens, i got a big chunker on mine! But i got almost straight Rentals. I LOVE it so much now, its heaps more fun to ride through the twisties.
My mate on his R1 loves it just as much when he has a turn! So Renthals are a must!
I think your right, 3/4 sounds right to me! I cant tell u exactly but looks right! Migh have to jump on AusSF and sus out a new screen!
