Like the title says what would you get & why from the new current offerings.
Myself I'd take about any of the new six speed 300cc bikes. Just cause they're the biggest offered & an extra gear would be REALLY nice. In this order
KTM 300 , they're so refined & parts are available
Gas Gas 300 , Gas Gas has been making "sweet" trials bike for years & they gotta know 2T torque from that experience
Husaberg 300 = Light , would need to be a 2012 as 2013 has a PLASTIC subframe
& Husky's bike ummm ..... They "were" exceptional in the late 70's early 80's but the only truly great equipment they offed since is a CHAINSAW

Correct me if I'm wrong I tell me what I've missed or you think is the cat's meow
