To warm up or not to warm up

Here's a point that's debated often and that's, do you warm an engine up before riding/driving off or do you just take off from cold start. Some say modern engines don't require warming up however I find it very difficult to do this. I always relate a cold engine to myself when I first wake up you got to warm your body up before you get it to work otherwise things snap and tear. I've always done this with my cars/bikes and never had issues with vehicles showing signs of engine wear eg. blowing smoke or nasty internal rattles.

Any opinions on this?.......

Wonderful things happen when people cold starting their modern bike and cranking the throttle from the get go.

Serious though: I myself see it the exact same way as you do.
When getting out of bed, you're all stiff(pun intended) and need to warm up before you can have a run in the morning.

If you jump out of your bed and start to run immediatly chances are you'll get cramps in your legs.

Same goes for an engine IMO.
Its all cold/embiant temperatures and when the motor gets running all the metals need to warm up and expand before it can operate the way its intended.

Ofcourse you can cold start and redline it..but how many times can you do such things before something internally...cramps up.

Agree with above. I'll let run for only a couple of minutes, but then ride off keeping low revs until temp is up.

I cant help but cringe and wince when I witness this. Though, I see it often.

This!
Turn bike on, start engine.
Put on jacket, helmet, gloves. By then the coolant gauge stopped blinking.
Hop on and ride below 5k rpm first few minutes.
Slowly overtime building up the revs up to 8k rpm

Usually 20-30 minutes of riding is when the fun begins and 10k+ rpm gets used.

EDIT; just noticed this topic was in 4 cylinder maintenance section...oops.

Manual says not to leave bike ticking over but to start and ride it with the toggle choke lever on.

I start the bike. Put my helmet and gloves on and go.

Leaving it ticking over means there is poor airflow over radiator so cylinderhead, barrels and pistons gets hot, while oil is not up to temperature..

Personal choice but I follow the manual. Once it has started and I can hear all plugs and injectors are firing ...get on and get the air flowing through the cooling system.

Using the relating to body example.. todays fitness experts.. trainers.. coaches.. teach and perform 'dynamic' stretching. Its not a sit and stretch cold muscles.. its basically- warm up by doing 'easy' exercises and gradually getting to full tilt.

My vehicles get the same treatment. ill start and get going easy, shifting early and applying minimal gas until it gets to normal operating temps.

Good points,
I have done this on occasion when in a hurry. Moved off pretty much straight away, but gently. Not allowing the revs to get to high and gently up and down the gears until full operating temperature.
On a track day situation which is the only place I ride these days, this would be difficult to do as the rest of the field is going ‘hell for leather’ straightaway. First session for the day would be 3 laps building to moderate pace, then open it up. The rest of the day would be fine as eng temp would be held between track sessions.
Interesting stuff to diagnose and discuss as longevity and performance is effected buy this.

Question for you.....to try and put it into some context.....

How many of you warm up your car engine before driving off? I don't

Start and go. Keep the rpms low until you get to operating temperature. I heard this answer from Click and Clack, The Car Guys out of Boston. It does not hurt a car to crank and go. Do not crank at freezing temperatures and pin it. Common Sense
