I have been on a few forums, as every time I buy an old bike,I have to find out how it works! Ergo, the Search for the Holy Grail of Two Wheels, and the Book of the Dead for some bikes, as they don't support them anymore...
But, I will say, that this Forum has the most information and participation of just about any other forum I have joined. The COG Forum is great, and the Venture Riders forum was good, also, but is falling off and may be dead before too long. The Royal Enfield forum is dwindling, and needs fresh blood, but those old singles are fading fast.
The Honda CB750 has been an extremely long-lived motorcycle, and has most likely outlived its projected popularity in 1969. That these bikes have the appeal still as a great motorcycle, and this Forum proves that, is a Testimony of Honda's dominance through this particular engine design. They are still supported with aftermarket parts and accessories. I will keep my 1971 CB750 Four, and ride the wheels off it, and it will most likely outlive me... barring accidents hehe.
P.S.- Bill the Demon, good to see you here still!
