Dont know if this has been covered already but im well happy that finally one of the big tyre manufacturers are making a proper off road noby tyre in 120/70-17 size! As if that isnt good enough its the TKC80 that comes in the supermoto size. Now i know this i think i will keep hold of my XT for a few more years.

Here is a bike with them on:

Jesus Christ, that is one badass looking bike!

All good but that's mild dirt tyre...they are just the same as AVON distanza i had these on my xtx and destroyed them in a month for a true off road tyre for the front I've been told its 80/60/17 and they would be useless on our bikes to much power for them to grip in mud.
The only option is get a xtr and adapt a xtx hub to the other wheel or change the change the caliper and bracket to suit the big wheel,i myself have looked at this but cost to much...the other option is get a trail bike just for off road use...i would get a honda XR650R

Hmmmm...... What about the rear? I can only see a 150/70/17.....
All well & good, but I went on a dirt bike course the other weekend, & tried a KTM690 Enduro R, & also a KTM 350 (EXC I think). Anyway, the 690 had masses of power, but was too high geared & heavy for mud. The 350 was around 100kg & FANTASTIC!!!!!!! So: keep your XT for road only, & get a super-light dirt bike for off road.
I have yet to see a true dual purpose machine without the compromises......

I have TKC80 tyres, rear 150/70-17 and front 120/70-17. They are much better in mud and sand as Avon Distanzia (160/60 and 120/70). XT660 is never like really enduro or motocross bike but atleast I can now drive in mud, I don't need push any more like with Avon.

Has anyone tried 180/55-17 rear tyre in XT660? I found one rumor that 180 should be fit. Is there really space for 180? I measured that gap between tyre and chain guard is 10mm, so at least the chain guard must be replaced. Chain and tyre gap is 15-16mm... Measurements have been done with 150 wide tyre. Model is XT660R with XT660X wheels.
