When I lived in Washington, a lot the KTM guys were running trials tires on the rear. I'm always up for being the odd duck that's little off the wall. I'm thinking about trying it, but I thought I'd get some feedback here. Anyone run them and stop? If so, why? Or, does anyone swear by them and at what level do you ride? I'm a B offroader riding a lot of mixed terrain harescrambles and enduros.
