Really?, seem to work very well on my MHR and the 750 Katana I had and everything else I've put them on

[sinfull]

Sooooo ?

Wheel alignment or what ?

bored huh? Reviving old threads...
Dunno. 2hundy sommat worth of lazertec.
Bike is sick. Batt comes off charger today and hopefully it goes vroom.

Wasn't me, they dug it up yesterday
But that excessive wear would make me wonder if the alignment is out

Dunno. 2hundy sommat worth of lazertec.

Like my lazertecs, use em on the HD fronts and even being a soft compound they do 2 rears to one front, roughly 15,000 k

Go buy yaself 5m strechy cord, prop the bike level, tape the middle of cord to lower part of rear tyre so it dont drop (watch it don't slip into tread groove on the very edge of the rear, if the grove goes to the very edge that is) and set up a pin board in front of the front tyre, move and pin the cord so the cord is just touching the foward edge of the rear on both sides and measure the difference to the front tyre !

Or two alloy straight edges a far easier (but expensive)

Then double check the axle marks are correct, before ya wear a hundred worth of that new tyre out

asides from harleys being really gay, my rear has worn evenly, the BTs are reputed for being soft but i still wouldn't reckon it should chew a front out in ~6k but apparently it happens, particularly being a big bike.

i have plenty of string lines, and enough straight edges. i will check les alignment. if the fucker runs. (battery in <1hr)

axle marks you reckon... on the front you reckon.?

[James Deuce]

The axle marks on the swingarm. If the rear is out of alignment it causes issues front and rear. Usually, the axle marks are an approximation, rather than being completely accurate. It's a conspiracy by the bike manufacturers and tyre manufacturers to make us buy more tyres.

mmm. i went/go by how much of teh bolt is threaded into teh hole. and be it even on both sides. adjusted the chain not so long ago (a'fore it fucked out...) rather than the marks on les swingarm.

I am well overdue for some new tyres...the current 021's from new, are now 14,000+ kms old...
The front especially is in dire need of replacing, next weekend at the earliest, possibly the following, will get both front and rear new'd.
Right hand side is cupped.......more so than the right.

Well, for what its worth, I would suspect under inflation the cause of an uneven wear in the short space of time that the OP's tyre wore out.

Yes, yes uneven camber, cheaper tyre, but I am picking lack of air.

Be interesting to see what Maha's tyre has in it. This damage appeared after our big ride to NP a couple of weeks ago, pressures were fine when we left.

[Maha]

Part of my pre trip bike check is tyre pressure...both were fine (36F and 42R Cold)
I didn't check the tyre pressure yesterday before a 300 km ride. I did however, notice the wear, so after 1100kms, it had lost 10psi.

I wouldn't think where the bolt goes is any more accurately positioned than the marks for the adjusters. The only way to really know that the alignment is correct, is the straight edge method. Or string, but that's more fiddly and a bit of a PITA. Sounds like you're familiar with checking the alignment anyway.

Once I've done mine, I mark the bolts and just do the same amount of turns/flats on each as necessary.

I would have thought if alignment was the cause of that wear, it'd have to be so far out the handling would be bad, and a quite different feel left to right would be quite prominent.

Good luck anyway.
