Will this bike be too portly in the tight stuff? I've owned an 02 YZ250F and I liked it, but I felt it was a little top heavy and the front end pushed a little. So I sold it and I bought a KTM 2 stroke, and I loved the bike but I missed the smooth tractable power. I'm thinking of going back to 4 stroke and I found a good deal on a '00 YZ426. I ride singletrack with a good mix of terrain. Is this bike gonna do well?
