I got back into riding at age 58 after about 10 yrs off. Started riding at age 30. I quickly learned that my reflexes, stamina and skills had diminished. I rode several bikes that were just too race oriented for me. I got hurt on one of them and had rotator cuff repair. I have gone full circle back to my roots and am riding an XR 400. With a few mods to suspension, height, bars and sprockets I once again am loving riding like I did when I was 30! The bike has totally predictable power, is comfortable for long rides, has great suspension, turns like, well, a Honda! Every bike has a downside or 2. The XR is heavy and I have to kick it, which is really not a problem.. Both these problems are solved pretty much by momentum. You must maintain momentum by looking ahead, way ahead of where you are riding so mentally you have dismissed what you are riding over and you are all ready setting up for what's ahead. If you are looking down at the front wheel (which I do when fatigue sets in) you will get very slow and stall, and fall. I run my idle slightly higher also in case I chop the throttle I don't immediately stall. When moving with momentum the bike seems to glide over stuff that gives a rough ride and problems when putting along. I would say you are riding an intimidating bike and would be much happier on a trail oriented XR 250 or 400, or a CRF 250X/ new generation Yamaha WR 250F. I would stay away from motocross bikes. IMHO.
