How long would you expect a set of Dunlop D207 Sportmaxes to stay fresh in terms of stickiness? I only ask given I've had a couple of unexpetced 'arse out moments' on the R6 over the last couple of days, and I'm aware the tyres on it are the originals it came with, ergo, they're over six years old. Just wondering whether or not to get some fresh rubber before I try to fathom out how to soften the suspension slightly so it's not quite so jumpy mid corner if it hits a bump etc. TIA
