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..........
