What dirt bikes did you own during the 60ís through the 80ís?
my first dirt bike was a 1966 500 triumph T100C single carb 2 into 1 pipe on the left, brother had a BSA 441 Victor...this was before the Japanese dirt bikes cam in.
then had a 72-3 (the grey one) 360 Yamaha Enduro . nice engine crap for handling but bullet proof
a '66 Bultaco Sherpa S 125 was a riot...an old race bike that was drilled everywhere for lightness 26 hp at the crank and a flat track slider
and the last was a 73 Penton Jackpiner w/175 KTM
