These bikes run cool in general.
A 10-12 minute ride won't hurt it, even in the dead of winter. I'd just let it idle a minute or so before taking off. Letting it idle, and idle, and idle until the temp gauge starts creeping up in 5-10 min is a waste of time, and even though some guys here swear by it, really won't do anything to keep the bike happy. These engines are not grenading because people are not warming them up, we've never seen a history of that.
A good gauge is your choke. When you can let off choke and the bike still idle/etc correctly, then it's warmed up enough. Gauge may still read near naught, but that proves the combustion chamber is up to temp and burning fuel properly.
Remember the gauge is the coolant temp gauge, on the radiator, not an oil temp gauge off the block. It's not a direct indication of engine temperature.
