Honda PCX stock tyres (IRC) on wet
In a nutshell they suck! IRC & Honda - bad job :(
I've changed stock IRC tyres on my brand new Honda PCX 125 to Michelin City Grip. The difference is just stunning.
Stock IRC's are slippery and unstable when raining. Every wet, white stripe is a russian roulette. On dry surface they perform well.
Michelin City Grip are stable and predictable, they are just better than stock one's about 10 milion times :)
