So I've got a related question that I'd like some opinions on. The tyre codes on my 450 give the date of manufacture as 2009, which I guess is when I put them on. Since then, the bike has done around 200 miles and spent around 95% of the time off the road and in a garage while I tried to chase down a very, very stupid timing issue. In addition, the rear wheel has barely touched the ground 'cos the bike was on the centre stand. It's only in the last year or so that I've had any real use out of it.
The tyres themselves still look pretty pliable and as you'd imagine, there's next to no wear on them; there's certainly no cracking, bulging or anything else that would suggest they're anything other than fit for purpose. The riding I do on the bike now is back road stuff, and almost exclusively in the dry. So what's our opinion on whether these things should be replaced? Personally, I think they're still good enough - at least for now - but I'd be interested in other opinions, particularly from those who have low mileage bikes that don't go out very often.
And I say this with a decent comparator. I was wondering why the ride quality on my 750 felt unforgiving and a somewhat underwhelming when I last used it. But that was before I had a look at the date code . . . turns out those tyres are from 2006 and although the bike's had a similar life to the 450 while it's been with me, I think it had some use before I got it. So whilst those tyres also look reasonably decent, they've lost elasticity and started to harden. Replacing them is on the list of things to do once I've sorted out the CL77 engine . . .
