Nah, you have to push 50 to 60 to get them to seat. Those side walls could run flat they were so strong. Mitas e-07. Complete bear to get on. Solid as a rock and lasted 10k miles.
Dealer sent me out the door at 20psi on tires…….

"They" never 'adjusted it' like the A & P manual told them to do when prepping your bike after finishing its assembly.
Slap happy, gitt'er done attitude of too many dealer 'mechanics' & their bosses.
Is your headlight still WAY TOO HIGH also? The A & P manual tells them to put the windshield ON, TOO SOON!
"They" aren't going backwards, takes too much time!
Probably wouldn't Read the A & P manual If it was handed to them.
actually that is not true. For all loads the front is 21psi, but for loads over 201lbs, the rear is 36. What is odd is the scale is 21 or 36. That is over a 50% increase in pressure.
Your tires dictate pressure, what is stamped on the tire is what you should go by.
I'll suggest that you didn't read my posting very thoroughly!
You assume Kawasaki did have enough data when they made the decision to have 21 psi in the front tire for all weights and conditions, and either 21 or 28 psi in the rear ('08, see pic) depending on rear tire weight?
How many riders do you know that have ever separately weighed front and rear tires under loaded (or any) conditions? The vast majority of riders will simply say, "It's in the manual," as if that makes it correct.

I suggest at this point, we all agree to disagree. We all have our opinions based upon our own reasons with regards to air pressure. I value everyone's opinions and consider them all. But this topic is never ending.

...and we haven't even touched on the benefits of Nitrogen-filled tires! (For disclosure - I'm generally a 34/32 kind of guy, but with "regular" air...)

Wow
He posted “Kawasaki is still recommending 21 psi in both F & R tires, for average sized riders,”
All I said was that is not true, and it is not. Nothing to debate. The manual never mentions average weight and gives two pressures for the rear. 21 and 36 psi. For the 2022. I am not saying what pressure is good, bad, wrong or right. Just what manual states. I did comment on the range and pressure were odd. At a load of 214 it is 21psi and at a load of 216 it is 36psi. And at 215 it is either. By the manual. Just non debatable fact of what manual states.
I put in what feels right and watch the wear pattern.
I don't think it's a typo, unless the sticker on the LS swing arm, the Owner's Manual and the Service Manual are all typos. They all read the same. I do agree that 21 psi is a bit soft, I've been running my front at 25 psi cold, no issues, and it's a little quieter.
No, that is incomplete/ incorrect quotation on your part.
I said "one might find that Kawasaki is----------------------------------------------------"
I do Not have a 2022/2023 owners hand book to read.
I beg to differ. Kawasaki printed the manuals, I did not.
I dis-agree with Kawasaki manuals on numerous things & I'll tell anyone my views when I feel the/they need.

You know that’s funny someone should bring up Nitrogen. The military loves it. I love it. I think the issue is the cost. I almost dumped 5k on a machine that would last longer than my expected time on planet earth. I would love to run nitrogen in all my vehicles but in the end I just dumped a few hundred on a good line dryer for my compressor. I still have a nagging feeling that I should buy the machine and add it to my home shop. I get enough people using my lift that I could make way more back in beer (my entrance fee to my shop if you need my help) than the machine would cost....and we haven't even touched on the benefits of Nitrogen-filled tires!

I think the biggest advantage to nitrogen is that it doesn't change pressure as much as air in response to tire temperature. I believe this is why the military likes it for aircraft tires (as do civilian airlines) - because those tires go from as low as -40 or -50° at altitude to smoking hot at touchdown, and minimizing thermal expansion/contraction and the associated extreme pressure changes associated with oxygenated air is critical for tire longevity and aircraft safety.
As regards nitrogen's molecule being larger than oxygen's and thus having greater resistance to leaking directly through the tube wall, the air around us is already ~78% nitrogen - if leakage through the tube walls is the sole source of pressure drops, a few top offs should mean one is soon approaching 100% nitrogen as what's leaking out is the oxygen. That said, I would personally put nitrogen in my tires if it were ready available, but I wouldn't pay extra for it.
Edit: Changed "air pressure" to "tire temperature." Good catch Mr. Westman. I try to proofread, but I always think I wrote what I thought I wrote.

Ah - thanks! I knew that there was a rational explanation for the use of nitrogen in tires, rather than cheap, old air; my neighbor told me that his bike has nitrogen in the tires because it makes his bike faster, but then he's so full of it...(hot air, of course!).

So the OCD part of me likes the fact as temps go up and down in the winter where I live…. The tires would stay the same pressure. Now with our KLRs we burn tires pretty fast but for instance in a higher end sports car pressure matter more. I had an old Camaro that had pretty fat rear tires and I kept 35 in them. As I ran back and forth to west palm beach and work every weekend I noticed the middles of the rear tires were wearing faster than expected. I suspect the pressures went up on the highway and I was at a higher psi. All in all I agree. If the guy at the shop asked me if I wanted nitrogen for free I’d love to have it.
