hello all im new to this and need some advice please? i got 160mm rotors with hydraulics on rst gilla plus t6 120mm forks.the brakes are pretty good but could be better so was thinking on upgrading the rotor to 203mm but one of my local bike dealers says the forks will fall apart as soon as i touch the front brake? any of you think its true as i seen the focus fatboy and other bikes with the same forks an 203mm rotors. sorry its a long question. lol. thanks mike.
