Knuckles - re-read the title, You have your "ai" reversed. It is "Trials" not "Trails". As in a bike that goes up the side of buildings and crap.Im on a yamaha 2008 TT-R 230. Its a great bike for what it is. It's fast (not a whole lot of torque tho) but it can handle a lot of whatever you throw at it. Super easy to maintain, parts are easy to get, simple design, and it's got an electric start. The only thing I don't like about it is that it's 300lbs. I've never had a problem with it.
I'm actually selling my bike for $3000 obo because I want to upgrade to a 250.
I hear Honda and kawasaki models are pretty good too. I haven't heard much on KTM for trail bikes. And well Suzuki...is Suzuki.
