need some advice,i have just bought a ybr but the tyres on it are the sakura ones,when i come out of bends the bike feels a bit unstable(tyre pressure ok),the bike i learnt on was a ybr but did not feel like this as tyres were not as chunky as the sakura.i have been told to get more of a road tyre like mitchelin piloy sporty or pirelli city demon so does anyone know what would be best tyre for grip and smoothness.thanks.
