I have been looking for a "tweener" bike, that is something great for trails yet nimble, snappy and light enough for an occasional run on the track. The XR 250 I now have is great as it's reliable and easy to ride but is a bit of a slug. From looking around it seems the WR 250F, KTM MXC or EXC might fit the bill. I live in SoCal so I need a green sticker bike which negates the WRF and new KTM's. I am looking at used KTM's with the green stickers particularly a 99 380 MXC, 99 250 EXC, 98 250 MXC and a 97 300 EXC. I returned to riding a few months back after a 15yr. break so I'd like something that is controllable yet something I could advance skills with and not outgrow. Maintenance ease would be nice as well. I am 32 , 6'0" and 170 lbs.
What I am asking is,
1) Which KTM, listed above or not, would best fulfill my needs?
2) Are they reliable and easy to maintain?
3) Are the MXC and EXC that different?
Thank You
