Husaberg to start with??
Hey, wannahusaberg...
Welcome aboard!! Lots of info on this site, and lots of members ready to opine!!
Logical step from a 230 would be to a fe450 or fc450, but even a 550 is very rideable. Husabergs don't seem to be "violent" bikes; they all have power, torque, and handling, but all are manageable.
I got my '98 in 200 winter, and I had been away from dirt bikes since the mid-'60s. The bike wasn't a handful, just so much better than the old Brit-bikes of that time (desert sleds) that I had to be a bit respectful of its capabilities 8O versus my ability

Where and what type of riding you do may influence your choice. I ride mostly trails up here in Maine, and in some of the nastier areas I suspect a bit more maneuverability, such as an fe series, would probably help; if you are riding mostly open desert or fire roads, or mx tracks, then the fc might suit ya better.
Any one of the Husaberg bikes will be a blast! for more info, just watch the posts and ask questions. A lot of the members have had, or still have, multiple 'bergs, and can tell you how the bikes are different on a ride.
