What's the difference between a motorcycle and a vacuum cleaner?

[MD]

I heard this on the radio this morning and it made me laugh. It was told as a dig at Harley Davidson bikes, so in the interests of not upsetting our Harley riding buddies and political correctness I have cleverley switched the words 'Harley Davidson' with 'motorcycle'. Feel free to insert any brand you like.

So.
