I know verry little about these bikes, but i did get a chance to ride one quite a few years back.
It was a GasGas 360 2 stroke, revved really high and went really slow, it was an absolute tractor powerwise. and felt light as my mountain bike with a really low center of gravity. Suspension was long and really squishy. If you plan on sitting while riding then dont buy one. trials bikes are pupose built and do it very well. Alot of fun and wish i had one. I think it would be an excellent training tool for balance and control on any bike.
