Well.... I was way off.
How about some Pirelli Diablo Supercorsa's.
Front 120/70 ZR17
Rear 160/60 ZR17
I know... The rear will rub...
I didn't want a 160 in the rear, I wanted a 150.
My tire guy said he couldn't get what I wanted in a 150... (Cheap but awesome, actually trade)
I measured it at 155mm.
I measured what is on my bike right now and it is very close.
I guess we'll see when I get it mounted.
Unfortunately it won't be till next week as too much is happening right now..
These were mounted on a bike that took a couple of laps.
Still tons of life left
