| They are a great tyre for road/ light/moderate trackday use, I used to ride to Croft on my old SP2, do a track day then ride home. Managed to get them sliding once when they were really warm but only after a slightly longer than normal session. Take first 2 or 3 laps steady as they wil be cold but they aren't as bad as the older design Michelins. Even with a 999 having more power than the SP2 I don't think you'll cook them in 3/4 laps. . you could also go for the new Michelins which are meant to be even better for track days but according to my mate who works for Michelin the Pilot Power is the better option if you are going to use the same tyre on road and possibly in the wet on road. if you are fitting a tyre just for a trackday then go for the Power race as it will have more grip. I've just orderd a pair of Pilot Powers. |
