My brother rides a DRZ 400 in the dirt. Never have had it in the snow so I'm talking a guess on what I would think. To start its a pretty heavy bike and the suspension isn't up to par with the motocross bikes that have been around the last ten years. I don't know for sure if there is a fit kit available for that machine but the couple different Snowbike manufactures I've dealt with have been very helpful and I'm sure could help you with that. Power wise they have a fair amount, but they don't have the top end scream or power of a newer bike or the ideal gearing. But if you just want to get something together and you like that bike in the dirt it could be a good Snowbike, just keep in mind there will be significant gains getting a higher performance machine. Hope that helps.
