It bloody did. Me and a mate did A5 to N. Wales, across to Chester (bought a new jacket from Hein Gericke...another story) then back down A41 home. I don't think I've EVER ridden in such persistent, hard rain (coming back from Scotland a few years ago was the nearest).
Have to say the old bird behaved impeccably, no scary moments or concerns whatsoever. The pace was virtually as brisk as it would have been in the dry. Even the Kappa top box was bone dry on the inside.
Bless.
