Hey Chris,
Nice bike mate. We'll be seeing it in Wales pretty soon then ?!
I have been considering Metzeler Karoo MCE 's for the KTM
I think that the guy with the HP2 has one on the front ( Sorry can't remember names ! ).
Check out the links below.
I normally fit my own tyres and I've used Moto Tyres before.
Delivered to my door within 2 days.
Some fitters wont fit tyres unless they supply them tho.
( Santrix has found a good fitter )
See the link below and just punch in the sizes and leave the speed rating blank you will see a good selection
of types and brands
From memory they will be 90/90/21 and 130/80/17

I found that the TKC's on my 640 ADV were terrible in the mud the other weekend and the rear one seems to loose rubber every time I go out on the bike !
All of the single cylinder bikes I've had eat rear tyres, chains and sprockets !
Then again if you have bought the Yam as a second bike for more dirt based riding you could go for a more aggressive pattern ?
