There is no tyre which will give good grip on road and off road. Every tyre must compromise to pretend to do both well. The Siracs on my R here in Spain have done well on road and tracks of a very gravelly and rocky kind but I avoid grass. I have a pair of Annakees which I am hoping may give some benefit in wet off road conditions but have not yet tried them.

Following the discussions on trail riders suggests that TKCs will give the best off road performance whilst still being reasonable on road. Clearly any nobbly tyre will not be so good on tarmac but it is partly simply because they wear very quickly on road.

Maxwellnumbers will be along soon to tell you about his tyres and CaptMoto will sing the praises of Tourances but no keen off roaders have said anything special about them. Jasext is probably the best guy to give you advice as he is both on and off road enthusiastic.

Perhaps should mention that whilst people refer to off road as if it was all the same there is a lot of different kinds of off road from mud and slippery grass to fairly stable forest tracks and my local gravel and rocky tracks. They each need a different tyre to get the best performance.

Firstly what type of terrain offroad are you doing ? ie mud ,grass,wet,rocky

As for grass the you will have to fit a front tyre with very small knobblies as the larger knobblies tend to hover over the grass and not dig in to grip ,maybe try a michelin ac10

For the rear a pirelli mt21 is probably the best for mud,wet conditions (welsh ) and will grip brilliant on the road (i have actually scrapped my side stand in the wet ) but they only last for around 1000 miles at best

Been told that a michelin t63 is a very good compromise but havent tried them yet also a dunlop 908 rr but a bit pricey for me


DO NOT USE TKC80 IN BRITISH WEATHER IF YOU TEND TO GO OFFROAD

Hope this helps a bit more
