This motorcycle has been discussed a few times here on ETS. Even five years ago they had a bad reputation for quality control. Someone on this board said that they've been greatly improved and are now much more reliable.
The ability to run it as 2-wheeled drive is good and supposedly they can handle some pretty rough/slippery/muddy terrain. Plus, they look damn cool.
Personally I say if you have the cash get one and report back to us. Better yet, pass it around to a few of us with motorcycyle licenses and we'll all report on it.
