I'm 32 yrs old, 5'6", 28" inseam, and 115lbs soaking wet. I will be buying a used bike in about a month. This will be the my first motorcyle in 10 yrs. ATV's filled in the gap. The last bike i had was a 1982,83 YZ100 and I hated it. It had one speed W/O and would not climb a hill except via momentum. Not a good choice for a trail bike. I have had people recomend a KDX200. Very tall seat. I'm thinking a KX100. I don't want to have the same issues that I had with the YZ. I have read many treads that say the KX is a great trail/woods bike, but then ask haw they can improve it. MR. Gorr can a KX100 be made into a competent trail bike with some of your magic? 2nd are there any years better or worse. 3rd am I making a bad choice all the way around?
