I'm use to running old 2 stroke bikes from my youth so I'm wondering if this bike I'm buying tomorrow will be a decent trail/woods bike? I'm not running any races or anything crazy but I do like the power and few guys say this thing will be crazy fast, almost to much for trail riding. The bike is very clean and it's a good price so that's why I'm buying it and I've always liked Yamaha bikes. Any thoughts or tips? Are these 450F bikes high maintenance compared to most 4 strokes or even 2 strokes? Thanks.
