I just picked up my new WR250R yesterday. I started on a Yamaha 55cc step through when I was about eight years old in the early 60s. Made the "big move up" to an 80cc Yamaha Trailmaster shortly thereafter. The only bike other than the WR250R that I presently have is a 2WD Rokon Trailbreaker of about 2005/6 vintage.
Thanks in advance for all the useful information and advice I expect to receive!
