SuperMaxxis - cheap crap the bike came with gripped well but sustained fast hard riding cooked them and contributed to me highsiding at 15 mph, D'oh
020s - my favourite as sticky as 010s when there warm but wear better.
010's - as sticky as anyone will ever need on the road and not bad wear.
014's - loads of grip (even all thro the winter) but wear out quickly.
On my old 400 I used BT45's which were always fantastic.
And on the little 100's i had i use to find Pirelli MTs worked best.
Would love to hear more info on continentals and avons - has anyone ridden really hard on these tyres??
