I would recommend the Suzuki Dr line.They have all different sizes of engines that can suit any age and experience level.They are very comfortable with more of a trail bike design but they still retain all that four stroke power which is also a plus for an older rider because you don't need to mess with all the two stroke oil mixing and plug issues allot of two strokes have.If that is not what your looking for I would still recommend another "enduro"style bike.These bikes are all great for older and inexperienced riders who want a capable bike without being scared of it.I would also stay in the 200cc range,anything above that gets a little harder to hold onto.Enjoy the spring
