I’ve changed my GP 4 Seasons for GP4000s and I’m not sure about the reflective strip. It somehow makes the bike look a bit less stealth. I appreciate safety angle but it’s going to make it harder if I ever have to take on any two wheeled ninja missions.
I quite liked the all black effect of the old tyres. I’m sure I’ll get used to them. Hopefully.

Excellent tyres except that I’ve destroyed my last two with cuts in the side wall – take care on the rough stuff.
