Steve McQueen's Motorcycles

Recently finished reading 'Steve McQueen's Motorcycles' book.
A couple things I noticed, that you folks probably already know. Both Steve's bikes and Malcolm's, pictured in the book, are all right hand shift. I also saw Malcolm's bike from 'On Any Sunday' with a right hand shift as well. Hadn't noticed it before, and was wondering if they all came through the factory that way before 1973.
Great book by the way!

Shifter was on the right side on Euro bikes prior to 1975. everyone to the left after.

there was a kit to reverse them, but I don't recall from where

Bikes sold in the US were right hand shift on 71 and earlier, the 4 speed's. 72 and later were lefty's, the five and six speeds.

On Any Sunday was released in 1970 or 1971. I am not sure which now but I do know Jeff Ward was 5 years old popping the wheelie on the Honda 50

July 1971
