Get one, you will not regret it.
I am almost 16 stone and it goes up anything i throw it at, when i doesn't thats down to me, a beta 200 is a great bike.
At a really wet trial i was sitting in the queue, the section was a tight turn and an S type turn up a steep bank of approx 30 ft, both the 290 Sherco and the Mont in front of me failed to get up, my little 200 climbed out with ease.
One thing i have found is that they do not rev as hard as Sherco or Gas Gas
