guided for some mates recently,2 x new Africa Twins and a KTM 1090I tried to do a rally once on tyres like that you are wasting your time also no good using tubes or tubliss on a bigger bike off road you will constantly be fixing puntures. Metzeler six days front and Maxxis IT rear with mousses is what you need for off road, fit them trail tyres on another set of wheels for the matcho look outside starbucks if thats what floats your boat.
the A/Twins were on enduro tyres and did a fair pace on a wet day
the lad on the 1090 was a lot slower and struggled to keep up 'cause he was on trail tryes
he finished Romaniacs, Sea to Sky and the 'Roof' in silver class on an enduro bike, so this guy could ride a bike
i never ride on the dirt without an enduro front tyre
you need to know that front's gona grip 'cause dabbing 200kg aint fun...
