J&R silencers

A fine collection of mid-seventies J&R silencers. These were made and sold as a result of the general environmental awareness including the Less Sound-More Ground movement of the time. Fine on trail bikes and street bikes but also required on racebikes where they were not universally appreciated, races are supposed to be loud! 
MotoGP agreed with that view, allowing open pipes on the racebikes when the formula changed to fourstrokes in 2002.
