BT-015 OEM tyres - wtf ?

[BikerBoy]

I found the OEM's took too long to warm up. Not a bad tyre but I wasn't confident at all with grip and the shit cold grip was a significant factor of my lowside a while back. Am I right by saying (been told) that the factory fitted 015's are not the same tyre you'd buy off the shelf?

I ended up changing to 016's and am yet to fault them.
