D208's were/are fitted to my sps when i bought it. They are OK but when they are due to be changed its either going to be Bridgestones which have always worked for me, or More likely Diablo's to see how they compare, and have had many rave reviews on the board.
I replaced the original Michelin hi sports on my 900ss with D207's. The bike's steering is much lighter and quicker with the D207's, don't supose the D208's would be much different.
Much prefer the D208's (standard compound not GP) I have on my 748 now to to the Pirelli Dragon Evo's they replaced... They seem more consistent... Though to be honest, I've not put many miles on them yet...
