R1150GS ADV 21” Front wheel tyre?

[stephenenglish]

Has anyone any experience on what type of road legal tyre to use for off road use on a R1150GS ADV 21” front wheel?

The rim fitment guide is a TKC80 90/90 21” 54T Tubeless.
I have been using TKC80s on the 19” but the 90/90 looks a lot different, not so knobbly.
Can anyone help


Regards
Stephen

hi.

90/90 - 21 is what i've got on the Dakar (Tourances by the way, not TCK's).

I didn't even realise you could get a 21" wheel on the GSA.

I think that 90/90 might be a bit too small and unstable on such a big bike, but i'm sure someone on here will correct me if i'm wrong

Someone can correct me if I'm wrong, but I believe that the 21" wheel is a conversion which was originally done by someone in the Netherlands, by lacing an R80/100GS front rim onto an 1100GS hub. This would give the 90/90 R21 tyre fitment as being correct - great in the dirt, but I wouldn't want to try hard braking/riding on the road with that choice of tyre size. I think the 1100/1150's brakes & weight would overwhelm the tyre quite easily....
