Got the Pro Streets fitted (749s) just in time for the Brands GP trackday on Monday just gone. Scrubbed them in the day before. They seem to warm up quickly enough for road use (in the dry anyway!) & offered good grip, etc.
On the track though, they are superb. Nice turn-in + they feel unbelievably stable on full lean. Only problem now - ground clearance! The side stand touched down
It was raining for some of the journey home from Brands. Although the lack of tread doesn't exactly inspire confidence, they were ok for my very gentle ride home.
