How long to warm up ninja 250

For the Ninja 250 riders out there, how long do you warm up the bike before going?

I'm a noob, and I've been told by the previous owner of the bike that he let the bike warm up at idle for at least 5-10 minutes. I'm impatient, so usually I just start and go, though I go easy on the bike at first, and not rev as aggressively til I rode a few blocks.
Is it bad that I don't warm up the bike longer?

Any insights appreciated!
 
5 -10 mins is too long.

Just start the bike with choke on full. Let it idle for approx. 1-2 mins then slowly turn off the choke. Let the bike idle for another 2 mins tops on regular idle. To check if the bike is warmed properly, just twist the throttle (let if rev up to 3,000 rpms) and release it. If it returns back to idle rpm (1500 - 1800 rpms) without any hesitations. Then you are ready to go.

For colder days, I usually let the bike bike warm up with the choke on for 2-3 mins and regular idle for another minute.

I can't speak to the Ninja 250 specifically but unless it's a wicked cold day and you are not using a synthetic engine oil even two minutes is unnecessary. 5-10 minutes of full-choke idling will carbon-foul your spark plugs, not a good idea.

I've always started my cold bike with choke, then put my helmet and gloves on, hop on and go (1-2 minutes). As soon as I'm up to speed I shut the choke off and just take it easy for another minute or so for the engine to fully warm. You are not hurting your engine at all by doing what you are doing - if you use synthetic oil you can theoretically start riding the second your oil pressure is up (3-5 seconds?) without doing any harm. Dino oil takes a bit longer to flow due to increased viscosity on colder days but even modern dino oils do a great job in the kinds of temperature ranges you will ride in.

The only bike I was ever aware of that needed to fully warmed up before riding were the old RD/RZ350 2-strokes; they would suffer from something called a "cold seizure" if ridden hard without a proper warm up. The "cold seizure" was due to the pistons warming up and expanding faster than the cylinder bore. That was a long time ago and even then cold seizures were rare - I've never heard of a cold seizure issue on a four-stroke.

Ride safe,

There are multiple threads on this. Start bike, get on, ride is the short version.
 
Thanks for the tips!
I suppose I'll try to search through the forums more before I ask noobie questions next time.

Hi ahoy11,

Ask away. There is no harm in asking the question, especially if you are new.

Sometimes folks forget what it was like to be a noob and assume that everyone is an expert at searching the old threads, either that or they are using the old "multi-thread" reply as a way to build their posting-count to make it appear they are contributing something worthwhile! As a general rule I try to only post when I have something to say that adds value.

Personally, I find the search capabilities clunky and I often have trouble finding a thread that matches exactly what I am looking for.

Enjoy your ride.

Daryl
