After an extended winter sojourn on a CB500 twin sidecar outfit, I made an interesting discovery. Upon my return I dug out the venerable XBR500 works outfit and I was fully expecting to find it to be a gutless old slug compared to the more powerful and gruntier twin. Not a bit of it. The XBR is actually a nicer bike to slog around on with a chair. The bike will pull from stupidly low revs and despite accelerating very slowly it does get up to a reasonable speed and, dare I say it, it's a lot more fun to ride.
There's one other aspect that I was surprised to find I'd missed on the twin, the bloody sound. The twin still has a standard exhaust and all I can hear from the cockpit is an annoying engine whine that doesn't really help you gauge what revs you're pulling. etc.
Having said all that, the CB500 will sit at 70mph on the slab and still return 50mpg, compared to the XBR's 60mph and 35mpg. Still... I do like it more.
