Not sure I buy the whole heat cycles thing, unless you're pro level. I use warmers and think of reduced heat cycles as a side-benefit, so I'm sort of argureeing with you....
I probably put about a dozen track days on my motard rear tires and probably twice that number on the front. I use them until the meat is gone and I don't notice too much of a difference. At least not anything I wouldn't attribute to whole less rubber, less heat thing.
I can't imagine you get more than 6-8 days out of the tires on your Aprilia, no?
I guess I'm just writing b/c
1) It's past 1 am and I can't sleep anyways
and
2) I feel like there's a lot of exaggerated information, if not outright misinformation that is spread by the tire companies that's really more about marketing more tires to people than it is about helping people go faster...especially for people who aren't at the AMA pro level or above....
Heck, I just got my hands on a set of take-offs from a novice with a couple of races on them, ~90% remaining tread life and chicken strips about an inch wide. Maybe I should shut my mouth and let people practically give away good tires over "heat cycles"
[EDIT: Right after I let my cynicism fly, I see Tony's post debunking the heat cycle fear - not to mention my cynical post. Thanks for spreading good info, Tony]
