The deciding factor for me was the gear ratios on the DRZ. It really needs another/higher gear. If you are not going to do much pavement, it's probably not a factor. I'm a dirt rider, but it seems there is always a good bit of tarmac on every ride I do.
On the '99 DR350se you can add a kicker, if you want to.
BTW you can get a wide ratio gear set for the DRZ....It's a little pricy and would be a little work....
