I'm 6 foot, 210 pounds, 28 yrs old. I've been riding since I was 7. I've owned mostly 4 strokes, but I've had a couple 2 strokes too. I had an 83 xr200 for a long time, 2 different mid 90's xr600's and a cr500. I've had a couple other bikes, but those are the main ones. Right now, I have an xr600. It does what I need it to and it's awesome. I mostly ride trails and dirt roads out here in Utah. I also do the occasional hare scramble and want to do a couple enduro races if I can find some in Idaho, Colorado or wherever. The xr600 is just too heavy in the hare scrambles and I know will be worse in a long enduro race since most of those are much tighter. I'm thinking of getting a second bike that will be lighter and more agile for the races and any tighter single track I ride. the xr600 I'll keep for the dual sport rides and such. I'm thinking of getting a later model kdx 200/220 or an xr200/250. I've only ever ridden an xr200. the other 3 bikes, I have never ridden. I'm really not worried about maintenance on 2 vs 4 stroke or anything like that. I'm sure they are all good bikes. I would probably go for a crf250x, but I just don't have the money. I'm kind of on a 1500 or so budget. All of those bikes can be gotten for that in my area. I'm not a serious racer either, just looking for something that's lighter than the 600 so that I can last longer in the races and have something that's good in the tighter stuff. if I were to get serious into racing, then I'd get a much newer bike at that point that has better suspension, power, lower weight, etc. Questions for those that have ridden these bikes before: 1. the xr200 is quite a bit lighter than the xr250 according to the specs I saw. Since I've never ridden the 250, does the 250 feel that much heavier than the 200? 2. how does the power off idle and in the lower rpm's of the kdx's compare with the xr's? 3. how does the power off idle and in the lower rpm's compare between the kdx 200 and 220? 4. the kdx 200 and 220 had the same approximate weight in the specs I saw. does one feel lighter than the other? 5. anybody have some opinions on the suspension on the 4 bikes and how they compare? 6. anything I should look out for on the kdx? I have never looked at one and don't know a lot about the changes made on them over the years. Either way, I think I would look for a 2000 or newer. 7. the kdx has a reasonably large fuel tank, but what kind of miles does one typically get in single track out of a tank? Thanks!
