Hi TTR600 owners. Anybody know where I can pick up a set of SuperMoto wheels for my TTR600, I have it fully kitted with knoblers @ the moment for green laneing etc, it rides ok on the roads but a little twitchy if I lay it down at the corners, so I thought if I could have a different set of wheels with Moto tyres on, then I could use them when on road rides. Any help guys & gals would be appreciated. Yam 4ever
