Tea tray - personally I like it on my monster because of having higher level pipes it just suits my bike - IMO...
Now - with the Buell I couldn't wait to really shorten the already very short thing and make it miniscule but the effect of riding through anything remotely wet is of course to leave a trail of interesting splashes up one's back, and not necessarily in a good way!
Putting tea on the tea tray, or not - as shown by Slob, is an integral part of still having the aforementioned tea tray thingy - but those of us who haven't been cut (ouch
) would always let those who have share a space upon which to place one's cuppa, fags, spex or anything else for that matter.
