After the SOHC4's many of the Japanese bikes became the UJM, the Universal Japanese Motorcycle. The SOHC4's are the standouts that attract people to them like bees to honey, like men to boobs.
Cliff.
The SOHC4 was actually the pattern for the UJM, coined by CYCLE magazine in 1976, pre- Honda DOHC.
http://en.wikipedia.org/wiki/Universal_Japanese_motorcycleapplied retroactively to transverse mounted 4 cylinder bikes, naked, front disc, etc. incl the 69 CB750. I remember reading the CYCLE issue whne the UJM was first used.
Still, your point that the SOHC is the standout in terms of attracting people, I agree.
The SOHC as UJM is unique to Honda I believe?
Something about that DOHC head, with generally bulkier looking carburetors, which, while the better platform for making power, loses some of its down to earth, I can still be understood by a mere human, look, that the SOHC has.
