I found a few pics of me and my buddies with our Fronteras, back in 1976.
First one is me showing off (I never did got over that habit
) with my 143, complete with my Bultaco jersey and leather pants.
The next 2 shots are me with my 143 and my buddies with their 152 Frontera 250's. Check out the Scott goggles and facemasks here.
Now all 3 of us at an enduro in Missouri about 1976. Had to be 1976 as 2 of us had out bicentennial (1776-1976) beards that were popular that year.
