Not a KTM guy but the way the world is these days that is pretty much the only bike everyone has anymore. So most of the guys started out with the dual season dream and everyone has given up on the idea and gone to specific set ups. If I was to do both seasons on a KTM myself personally I would go with the 500 whatever it is now, punch it out to a 610 for snow and use that torque for trail as I like torque more than rev for my trail time. All guys but one started out with the 450 but have since bought 300's for trail use. The 500 guy used his as a dirtbike last year, had it punched out, rode it twice in the dirt and it is now a dedicated snow bike and he went the 300 trail route as well. I go CR500 snow specific and CR500 in a 250x frame for the trail.
