With aluminum engines and steel bolts it becomes real important to warm the engine up before hitting throttle hard. Think about it, the aluminum cylinder and head expand more than the steel head bolt. Peak clamping pressure isn't achieved untill engine is warm. I wait untill my oil tank is warm to the touch before I leave and at least 10 minutes on the road before I go full throttle.

Motorcycles should be allowed to warm up but you should never rev a cold engine (car, motorcycle or anything else). When you first start an engine, the oil takes a little time to fully distribute and warm up and lubricate the engine properly.
Usually, you don't have to wait 5 minutes for the engine to warm up sufficiently. A minute is generally more than enough.
The manual for my Kawasaki KLR650 suggests leaving the choke open for a cold engine to help it while it warms up - but measures the suggested time you do that in seconds not minutes.

If it is a 4-stroke bike u sure need 2 warm up in order 2 hav a smooth ride & also 2 giv your engine a longer life span. Not 2 rev it 2 hard as it can cause engine damage. If it is a 2-stroke bike u can rev it hard as there is 2T oil mixture.

Not all but some do specify a warm up time. Fuel injected are less likley to REQUIRE a warm up time. But I would warm all engines for @ least a min. before increasing the RPS to get the parts warm and oil starting to flow to the top of the motor.

You should allow the bike to warm up yes, more important is that you let it warm up before you shut it down. If you start a cold bike and turn it off before the engine gets hot you can/will foul the plugs.

Not revved ,start a cold bike with the choke on and let it run until you can turn off the choke with out the bike cutting off,or until it sounds like your just stopped at a light.L.A.Deuce.

you do have to warm it up, but it is a bad idea to rev the engine. When you rev it, it causes heat which causes metal expansion. When you rev, it causes rapid heat and metal expansion and it will cause the different metals to heat and expand at a different rate which will cause warped heads and other warped gasket surfaces, which causes leaks, among other problems.

don't over rev it, but do let it warm up for a bit. especially with older bikes.

ive only heard "The 5 minit warm up period" applied to water cooled two strokes.. cause they have little or no power till they warm up literally..
