Howdy all,
If the weather cooperates, I'm taking the VFR to the track this weekend to dial in the suspension a bit. Any thoughts on pressure settings for PR2s? 30/30 hot?
Thanks!
I think that would be 36/42 if you're setting it up for street use, if setting it up for the track..... it would depend on the ambient&track temp/surface/riding style.....
Thanks Monk. I run roughly that on the street, but I'm looking for track pressures just for the weekend. Air temp will top off in the high 50s, I suspect. Anyone want to chip in on the anti rain dance being done on my end? :)
Assuming you mean Pilot Road 2? Used to be a line of DOT Race tires called PR, and those would be drastically different. The only street Michelins I've ever run on the track are Pilot Powers. Those are typically 30/30 COLD +/- a pound or 2 depending on conditions. I've known people running Bridgestone street tires (BT-016) at the same 30/30 cold.
Ask someone at the track, but don't set pressures before you get there. Have enough to bleed them down before you go out.
Better yet, pick up a set of street sport performance tires before you go! (as opposed to sport/touring tires)
Thanks!
I do indeed mean Pilot Road 2. My track bike runs race rubber, but this is a "new to me" street bike.
Most street tires seem pretty content on track at 30/30 cold. Assuming you mean cold, right?
The Michelin guy I've talked to at the track has always said 30/30 cold for his tires. However, I don't think he'd approve of using PR2's. While they are very grippy for a sport-touring tired, they really aren't designed for a high-heat application like a trackday. If you don't push it you'll be fine, but you'll be conscious of not pushing your tires and having less fun (unless taking it easy was the plan).
I would recommend calling the organization that is setting up your track day, getting in contact with their tire guy, and see what it would cost to have some more track-appropriate tires put on. A call can't hurt, and neither can a little caution.
