I have tkc's on my xt660z at the minute but need new tyres. what are then k60's like does anyone use them and are they hardwearing and what is the biggest tyre on the back i could use i read some people use a 140/80/17 would the bike need any mods to take that size back tyre. i want knobblies but road legal and have always used tkc on my bikes but any advice is requested.
cheers
