Warm up period - How Long????

so ive just worked 8-9hours (like many of you)...
..get outside, full choke, fire her up......

...put helmet on climb aboard....
...1st gear bite the clutch..... up through to second.....
..."i wanna let her rip now..............!!!!!"


come on.... whats a sensible time to wait.
so it gets nice and warm.

cheers, before i do too much damage....

I used to leave my Hornet until the temp came out of the blue, not so easy on the SV, sure someone told me a twin takes longer to warm so I usually leave it a couple of miles then let her ripppppppppp.

I have an SK4 model and it takes about 2.5 miles of town riding to warm the bike up (that is to ~85 degrees). By town riding I mean keeping it in 1st, 2nd, 3rd and not going over 5000 rpm. I also usually let it sit at idle for 15-20 seconds before moving off if the engine is cold.
