Never too old. I turned 53 today. 2 weeks ago I bought a 2003 plated WR250F with 800 miles for $2250.00. I haven't ridden a motorcycle in 30 years but decided it was time to get one again. At first the WR was a bit scary but I am getting used to it. One of my friends at work just bought a 2012 WR250R and another got a CR250L so I got the bug again. I wanted something light and fairly strong. Lots of good recommendations here. If possible ride as many different bikes as you can. Some are tall some are short. Shop around, there are some good deals out there. Good luck.
