It’s a single cylinder, and pretty much made for the newer rider. Uncle Bernie used to ride one and has since moved on to the S50, which he did a write up on for this site (check the front page). With any luck he’ll respond to this and you can get a first hand account of the bike. I wouldn’t worry about it not being a beginner bike though, it is. It may be 650cc, but the cc isn’t the sole factor in a bikes potential. To give an example a V-twin/Parallel Twin 650cc is much more new rider friendly than an Inline-4 600cc which could make you shit yourself.
