Hi Stephen, I have 208rr's on my Duke at the mo and 208gpa's on my track R1. Both are very good and give an increase in turn-in and lean, but are not totally stable compared to Supercorsa's, although the slide is very controllable (think Vellentino!, I wish...) but they take time to warm up on the road. Diablo's/Corsa'a seem to be very popular with the Duke guys here and are probably a safe bet, but mine are part worns very cheap so I compromise. Andy |
