Had them on for 8000 km, then the back tire was worn. Drove 99% on road, they are ok on dry roads, on large lean angles the side knob bends and you wear the inside of those knobs. On wet roads it becomes pretty scarry on higher lean angles especially when the tire gets worn then grip is lost in an instance. So on dry on/off road value for money on wet: please be carefull use it like you are using full knobbies.

Have these on my Ten and can't say that they impress me much. As others have said they are OK in the dry both on and off road, but off road in mud or on grass they just don't cut it and on road in the wet they do like to spin up.

Am fitting either TKC80's or Army Specials next, not that they will be any different on road in the wet, but off road in the wet I am hoping they prove to be better.

Well hell, at least we tried!:dontknow:

As an update, the rear was a slick after 4000 miles. This was contrary to what many had written on ADV Riders, where some users reported pretty impressive life out of the rear: 12,000 miles, IIRC.

A bit of further research revealed that the 140/80 (that they were using) has a different construction to the 130/80 (that I bought), and lasts a lot longer.

'Some users' always will. I met a chap at a local TRF meet who said he'd done about 12k miles on a set of TKC80's on an 800GS. My conclusion was not that TKC's last for ever, it was that he didn't know how the throttle worked :D

That's impressive, I managed 2500 miles on mine, and it's totally sh99ed. the front has worn in the most perculiar fashion and can't go round corners anymore without a bit of countersterr to get it over, then turning INTO to bend to continue around it, most bizzar.

I recently ordered the Heidenau's, haven't tried them before.
Hope they are just as good as the Michelin siracs, but last longer.
Drove 8600km's and i barely have a mm left.

I have tested them and I will never purchase them again:

Pros:

-Pretty cheap.

Cons:
-Almost impossible to break the bead at the rear, a tyre that has the word "enduro" on it side should be a lot easier to remove, I can not imagine that tyre in the middle of nowhere with a flat, the sidewall is sooo soft that you can bend the full tyre and the bead remains in place.

-The rear gets "squared" really soon at lasted me less the 5000km.
-Useless on muddy or grass surfaces.
-Scary on wet tarmac.

Other:
-Front has a strong V-shape, it gets smoother when worn, you may like it or not.

I will continue the search for the perfect XT660Z tyre -I know it doesn't exist, but the quest continues....-.

So far I have tested:

Tourance: The rear is unpredictable, my guess is that the sidewall is not flexible enough and the tyre "jumps" under heavy side load, specially when cold. Good lasting -8000km- and age well.

Sirac: So far the best I have tried, better than the tourance both on tarmac and offroad, they lasted me 8000km, also they age a litle bit better than the tourance.

Karoo: Honestly I don't know why this tyre exists, being a knobby tyre is almost useless in the mud.

K60: A cheap ****.

Brigdestone ED12 rear, dunlop mx51 front: Great for offroading, rear lasted 1500km. Scary as hell on wet tarmac, the only combo that I have not been able to lean the bike enough on tarmac, "lean enough" means the footpeg on the tarmac.

The next serious offroad trip, -it will be for sure after summer, now it's too hot for offroading- I will fit the noisy MT21, it should be better on tarmac than the above combo, meanwhile I have fitted another set of sirac.

have fun,
