New tyres? Yes or no

[darrsi]

Thanks again for all the advice, but one thing I have noticed and need to question is why run a 110 front as my front wheel is 120. So surely it's better to run pr3's or pr4's front and back

You're in the "General" section, FZS600's use 110 front tyres, whereas your FZ6 uses a 120 as standard.
