You won't get any joy out of Maxton....It is TT week and also once you have brought their stuff they don't wanna know you unless you show them some green

Age check done, seems to be mid-2007 on the front. I've heard of a rough 5-year shelf life, so I'm guessing I'm heading outside of that. But...

Had another look last night, the tyre hasn't squared off in the centre, but does seem to have a flat band covering 10-35mm from centre on either side (more on the right, roundabouts I guess). Have a sneaking suspicion that I changed the rear but not the front last time, so seems to have worn the front a bit. Guess a few hundred miles of watching myself to get some use out the rear, followed by some Rosso's in the near future!

Road camber is what tends to make it wear a bit more to the right off the centre line

I have read this through and nobody has mentioned the amount of rings showing through the yolk.
When I first got mine it had six showing and the bike tucked in badly on slow bends and tight corners, I have recently adjusted it so now there are three rings showing and the bike is better behaved and slightly more comfortable.

It is an easy enough job with patience.

This may be your problem. The tyre will have started degrading and won't be capable of offering the same amount of grip as it did when new.

Car tyres are reckoned to have a 6 year life cycle, but bike tyres only 5 due to the differences in compound and construction, never mind the completely different ways they're used. So if you're correct and your tyre is a 2007 (what's the date code btw?) it's too old and should be replaced.
I'm right 98% of the time so why worry about the other 3%?

sorry tony -
I would also be interested to know your fork settings
having said that the symptoms as reported would not be down to the rings sag etc - but could have been down to fork oil not being equal between the individual forks

there was a discernible difference in the volume on mine!

either way, glad we found a solution


Let's face it, you wouldn't go to a nurse to get good advice on a problem with a Falco - you'd choose an Engineer or a mechanic...

Must admit that I'm far from convinced about setup as this was a one-off - not something that happened or showed signs of happening before.

D-Riders link mentioned something interesting which Ive seen many times aand not been too sure as to what it was

Blue jay effect, IMHO suspect tyres, the reason I say this is my suspenders are no where near set up properly but does not give me any worries, the rear rebound is a tad harsh, but Im happy with the tyres

Not true, it has happened before, but generally when I'm pushing a bit harder into roundabouts (right-hander). Think this is the first time really for the left-hand, at least since I scrrapped the old Mez3's many years ago!

I think, all in all, it's a combination of old, flattened/worn tyres, and my own riding ineptitude/lack of recent miles. I think some new rubber to remove any nagging doubt, and probably more miles/bit of group riding with some well-mannered folks who would be happy to give some feedback. Any takers? (Any excuse for a ride-out :smt043 )

I had a series of front end slides (not on the faclo) that turned out to be due to a broken engine mounting bolt. Not got anything swinging about have you?

Much to my surprise I will refrain from adding any smutty comments here :smt002

Always up for a ride but why not take a trip to Steve at sandbach and ask him what he thinks and for a price on replacement tyre(s)

If the front's tucking on the road in dry conditions there's something seriously wrong or there's some diesel or similar on the roundabout.

If conditions are wet and the front's tucking, you're A) Riding too quickly or B) you need some decent sports-touring tyres to maximise grips and feel.
