Just been quoted £186 to have them supplied, fitted, balanced etc at my home. Anyone near Kingston or thereabouts do anybetter?
I found Karoos to be better off road on the 1200GS than TKCs, but worse on road. This was the standard Karoo, not the "Karoo T" as fitted to the HP2 by BMW.
I'm guessing the standard Karoo (which has much smaller tread blocks) can't cope with the power as well.
Another one to try would be the Metzeler Unicross, how these would cope with the power I'm not sure but the tread pattern is much more agressive than either Karoos or TKCs, and they come in a 17" size for the rear. I'm using a Unicross front on my KTM and it's way better than the others on soft terrain. Skittish on tarmac though - not a dual purpose tyre.
the karoos that come with the beast are good gear and give u plenty of k's (for a karoo that is) I have a desert on the back and i feel that the hp2 is a little kinda on the tyres as its lighter than my old GS 1150. I have an A10 michelin on the front which is a fully knobby and its crap on the road ,so i think (in my humble opinion) desert rear and karoo front is probably a good mix.
I'm using a 908RR rear on my KTM, pleased with it so far. After about 600 miles (including several trail rides and the Hafren Rally) it's not worn much. But I'm taking it easy on tarmac as the front tyre is a very knobbly Unicross.
(Afterthought - but does the 908RR come in 17" size? I can't remember)
When you say that the Deserts or Unicross are skittish on road, how seriously bad are they? I have to ride 30-60miles to green lane or reach Salisbury Plain and then the same back home. Are they up to these distances?
