I have Marchesini road and track mag alloy wheels on my 853 and ultralight aluminium alloy wheels on my 1098R and have had no concerns with either. I have also ordered the mag alloy option on my Panigale V4 Speciale. Would I like carbon wheels similar to the 1299 Superleggera ? Bloody right I would. Would I trust any of the wheels on some of the crappiest roads the UK has to offer ? No chance. Andy
