I had an '81 Enticer 300 when I was 12. Fun little sled. Very quick. Top end around 65 mph (speedo reading). (70 mph going downhill, on ice, and with a strong tailwind
) It could take the corners like it was on rails because it is light and nimble. Just under 300 lbs. dry. My father and I could load on the trailer by lifting it ourselves. (He had the front of course.) Not much of a ride. You felt every pump on the trail. However, you could serpentine all over trail to miss some of the bumps. 100 mile day is pushing it unless everything is well groomed. He will love it! Keep it well maintained. You cannot find a good little sled like that one now-a-days.
To your son - Don't let Dad drive it. He is to big for it. It will throw him off and run into an oak tree. Like what happened to mine.
Also, I use to find icy roads and get up to 20 mph and put it into a drift, and once I was facing backwards, slam on the throttle and do backwards burnouts seeing how far backwards I could travel before going the opposite direction. You should not do that!
