As an aside after 30 miles last week was suprised that there was no heat in the front. My other bikes always had built up heat (inc XTX) but not this one

You'll need to ride over red hot coals to get heat in the front!!

Mine did the same but at about 10,000 miles. Under noprmal running, fine, but under breaking it felt stiff and jerky. Took the bearings out and re greased them in the hope it would solve the issue. I inspected the bearings and they were fine but very dry. Its a known build issue that they are sparing on the greese during assembly. Put the bike back together and torqued it as per manual and all sorted. It was like a new bike.

Before the re greasing I didn't notice the issue in the workshop, only under load/breaking did this issue show its head.

A couple of hours, some grease and the manual and I reckon your issues will be solved.

Good luck, its an easy job.

Well, mine lasts 67000 km and was greased only once:).

Yes mine does the same but the rear tire is squared off.Ijust take its the crap suspension.:blob6:

I test rode one yesterday and while being mighty impressed, it did a couple of small weird handling thing at lower speed, which is really as already mentioned here. This bike had weird stainless bar risers on it and thinner bars so I was guessing it had had the originals bent at some point. I would say greasing the headstock is the most likely culprit mind. I wouldnt say it has crap suspension as it no worse than any Advtrallie bar for maybe orange ones with WP stuff, certainly no worse than my older Tenere and Transalps or even my BMW GS.
The bars do ... combined with the seating position feel very MotoX,supermoto, for a bike of this size mind, which I found nice, but some coming off more sane or road bikes might be put off
Mind with all weird stuff in mind I went and bought one:033:

MY XTZ has only done 2900 miles (09 model) is standard with Metzeler tourance tyres, the headrace bearings are also fine. I should point out that for the last seven years I have had bikes with 17 inch rims and I expected slower steering but this issue has me a bit spooked. I have also read elsewhere on the XTR forum that another member found tourance tyres going off when part worn. As soon as I get the bike back on the gas no problem and it could be me trying to ride the bike wrong and expecting too much from a trailie but any advice greatfully received - is it worth me changing the front only as the back feels fine to maybe a conti attack?

Sounds exactly where I was at 30k miles. Bottom head race bearing replaced - new bike.

Erm yeah, turns out my lower bearing is utterly knackered. It's been full of water at some point judging by the grease that was in there.

Amazingly, despite having massive dents worn into the raceways, cleaning it out and regreasing actually returned the handling to normal.

New bearings arrived in the post today, but I'll probably wait until the handling issues reappear before I bother taking it apart again :D

I would also say the head races are drying up. Normal test they feel fine but under braking they stiffen. Throttle on and they are ok again. Just undo and drop enough to get some grease in the bottom, the top one just lifts out. Bet you a pound. lol.

just a small side note to this

the greasing shortage isn't just down to the head race bearings. the front and rear wheel bearing are pretty much the same and the rear linkage is the same.

reminds me that I need to grease my head race bearings.

Just a point, but whilst everyone is thinking of greasing bits you should also note that the adjusting screws for adjusting chain tension that are in the swing arm actually go into the cavity of the swing arm itself. The exposed bit inside the swing arm can corrode and 'drag' the alloy if you are not careful. My point is that if you get the opportunity when the wheel is next out is to remove the adjusting screws and clean up, put plenty of grease on and if possible get some on the inside of the arm to cover the end of these screws to protect them. Hope this makes sense and is of some use to you guys.
