Fireman is right, Heiko you're close.
It is the Michelin SM cut slick in a 160. Mich does not make a SM specific full slick. I didn't have an issue with the change in profile but yes on a 4.25 inch rim it's not perfect. Ian ran it on his GP bike but it is the SM slick.
I used all the fronts Michelin has to offer (except SB slick) and the P1V is TITS, with the SM cut slick being my second favorite but they have distinctly different set up characteristics to go fast on both.
Run the Michelin's they're available and really good. Or the P's in 160 DOT's...more people need to take advantage of Clint's offer of set up help if you run them. New gen race DOT's are slicks with a tiny bit of syping.
For chain clearance rim offset and tire shaving happen often in the Ronin pits...
The nice thing in the improper profile change...it gives you a bit of chain clearance when it goes flat on the edges
Good luck getting Dunlops, Royce's dad imported the D's that were around last year and who knows where they are racing next year. They're hard to get here because of spec tire racing... I would assume getting SM D's would be next to impossible from a Canadian supplier...I dunno.
Edit: To get the best rubber you're' going to have to fit a 160. I didn't like ANY 150's I tried. Don't be afraid of race DOT's.
