78mph down the freeway, and just tremendous 2-stroke power and torque in the dirt, woods, hill climbs. Wheelies, jumps, climbs, and the all around finest hooligan bike I ever had. Most of it's life it had a 4.50 Metzler knobby (which was not exactly safe on the street).
That bike is how I learned to ride motorcycles.
Vintage 4.00 Metz of the time.

Love to do some of that again, but the reckless abandon of youth would probably hurt too much.
