this is what i have for my sm
front 17x3.5 inch with a 120/60/17
rear 17x4.25inch tyre 150/60/17
both are pirelli diablo rosso 2 you need the softest tyres in these size or you cant get the heat in the tyres, the 150 is the biggest you can fit with out rubbing keep the chain long as it will rub in the swingarm. i use two chains for my wheels
the front brake caliper is a brembo 22.5381, the bracket did not have any part numbers on
