M-12 front, S-12 rear, done 1000K's, still look great.
Hey, my right hand grip twists, whoa, it makes the motor rev, better not do that.
Ahh, just trying to say that I'm no throttle jockey, rip it up every now and then, and do a fair few road K's too. The S-12's on my mates RM's seem to tear knobs off quicker than mine, but all three of us love the S/M-12's, front or rear. Awesome in the soft stuff, without being too much of a compromise for other surfaces.
Sometimes pays to have a look at what the "fast" locals are running.
Have fun,
Peter.
p.s. I think Wattsy runs em too!.
