problem nailing it down ... easy there fella)

In the 60's they were called scramblers. I have a 1964 Yamaha YDS3
street model. In it's manual they refer to the YDS3C which could be
had with "Semi-up type" or "Moocross type" pipes. Gives a whole new
meaning to "cow trailing" ;) The "C" model had different porting for
better low end torque, different transmission ratios and different
sprockets.
There was also a scrambler version of the YDS2 which came before the
3. I have seen Honda and Kawasaki scramblers of the same era, and I
imagine others were making them as well. Not sure but I think there
were Triumph scramblers in the 50's and I know they were used off
road.

That's cool, didn't realize they called them something else back then.
Have to look up the scrambler style bike.
Anyway, seeing them up on the big screen made me think about it some, here's
the bad guys running down poor james on what looked like street legal bikes
with long front forks. Actually the ones show in the film didn't look all
that much different than what I see today.

I have a 1970 CL175 Scrambler in my garage that I really must finish up
one of these days...
