The CX was amazingly advanced for its day.  When you look at the engine and everything that went into it, you see that it had the barrels integral with the crankcase, water cooling, four valve heads, and yet was designed for easy maintenance as well.  Shaft drive, no torque reaction,light clutch, comfy seat....

It was as ugly as a hatful of monkeys' arseholes, agreed, but I'm surprised that Honda has never since made anything quite like it.

Have a picture of the early prototype engine that was taken from the water pump. The engine first started life to pump water from rice fields, that is why the water ways were so big on them. There was also the sandcast engines>> http://www.bonhams.com/auctions/21136/lot/206/

Where on earth did you get those pix from?  Also, never heard the water pump story.

CX forum club exhibit at Lotherton Hall Show (VJMC) in July. It's not the main forum, a 'splinter group'. The owner was an ex-hippy looking guy ! It was in a fold up wooden case.

I just had a look at CX500 specs, 50bhp and 46 torques, 14 seconds quarter mile, not bad performance at all for a late 70's 500cc twin, my party trick at the time was to power wheelie the thing in first gear (young and foolish), it did it with ease!, happy days, I do remember getting an enormous tank slapper on it once by cranking sharply around a van and cracking the throttle open, other than that it never gave a moments trouble, and yes that seat was extremely comfy, 300 miles in a day was no bother at all, anyway we digress..........
