Here's an example
of the "Classic" full-lock slide that you
had to be able to do to corner a modified 3-Wheeler.
I wore-out several pants from leaning too far at several
tracks. Although, I thought it looked cool at
the time, I really don't think it helped me that much
for lap times. It did help if you caught a rut or
another ATV while charging through a corner. Trimming
the steering stops was the key to this technique.
1984 Honda 250R, Armstrong tires, Durablue axle,
Bassani pipe... and that's about it.
