How long do you let your bike warm up before putting in gear and taking off? I guess technically with fuel injection it's possible to fire it up and take right off. Still I let mine warm up a minute or two while I put on my helmet and gloves.
So, how long do you let your bike warm up?
This is my routine as well.

In the "good old bad old days" leaving an engine at idle, to warm up, was not good practice. This led to (dare I say it) oil dilution and subsequent premature engine wear, particularly piston ring wear.
In today's motors, with scavenging (anti-pollution) systems, in all likelihood this is not an issue. However it is interesting to note that today most vehicle manufactures recommend start and then drive at moderate RPM and load until the engine reaches operating temperature. After that go for it. I must check my CB owners manual to see if any recommendations exist therein.
Cheers

strange, on the BMW car forum I belong too, many people point to the BMW manual that states not to let the engine sit and idle, to drive off slowly and, even though most of us think it's emission related, not really good for the engine.
I know I was in Canada once, letting my car warm up at a mountain lake area, someone knocked on my window and said I could get a ticket for letting my car sit and idle for too long, so maybe that is why BMW says to start moving.
Here is there quote from BMW 328i 2011 book.
-------------------------------------------------------------
Do not wait for the engine to warm up while the
vehicle remains stationary. Start driving right
away, but at moderate engine speeds.

I believe that every car and motorcycle that I've bought in the past 20 years, the manual says the same thing. I recall one even stating that driving away and keeping it at moderate speed until warm is better for the engine than sitting idling until reaching normal operating temperature.
Some towns around here have "no idling" ordinances, but you are exempt from that if you are at your residence.
