Here is one of the bikes that I rode growing up. A 1971 Suzuki TC120 Cat. It had a 3 speed tranny with a high and low range lever on the side case. (right behind my left heel). This thing would climb a tree in low range and maybe go 50 miles per hour in high range.
This was not my normal riding attire. I was posing as our family was getting ready to go to church. You can tell those are church going clothes, not riding clothes. (Can you believe anyone would were such gaudy clothes, I look like a pimp, and not a very cool one at that)
