Thanks... going to PM you so I have something for after this one wears out!
The trend is for bigger tires it seems. Maybe the 60 will be better. Not sure but if there is no longer a 55 option I'll have to go 60!
I can see them getting greasy on the track for sure. I'm running them on the street though and even then on a hot day I can see them starting to want to grease up. By street I do mean weekend riding which luckily is twisty and technical.
I have a moto D racing bike stand. I actually took a look at my clearance with 55's and I'd imagine a 65 is touching or coming real close. I don't use tire warmers on the street. I have done track at Barber with my MV Agusta F3 800. I had Michelin Power Cup Evo's and they did grease up on me even in Oct without tire warmers. Rear came loose on me after I picked up the pace and this was on an 800. Any liter bike at pace will overpower a DOT tire on the track. In the future I would not use anything but slicks and warmers at a track.
Thanks again for the feedback!!
