I don't quite understand the difference between motocross, dual-purpose, enduro, trail, etc, or the power/performance I should be looking for. I'm 5'10" about 200 lbs. and I've got some experience (1-2 years) on a smaller 80cc honda about 8 years ago.
I would do some short (< 1 mile) trips on the road to get to another part of our property, but the majority of my time would be spent in heavy grass, hills, and brush. I like manual bikes and prefer a 5 or 6 speed transmission in cars at least.
Suggestions on make, model, power, etc? I'm looking to buy used with good durability and low maintenance. I'd like something that maybe my wife could handle eventually also (so I can upgrade

Thanks in advance.
