On hot dry highway.. My-01 perform good, no problem at high speed..if you zig zagging on road.. not good coz the sidewall is soft.. might wobble a bit, worse when you use 60 series tyres. Emergency stop at high speed (let say 100kmh)is not more than average..
On wet road... try not to go more than 80kmh.. as the aqua planning (v groove) is not good or almost not there...not good for emergency brake on wet road..
Its good for city or long distance travelling as the comfort is there and low noise.
Its a no for track use only...
