My BMW has TPMS. Great peace of mind to have a system to alert you to deflation before catastrophes. Can't speak to after market systems but the concept is great.

The OEM systems are better than the add ons but I prefer checking them myself. The right angle valves on the Duc make pre-flight much easier..

It's such a habit for me to check pressure prior to an outing...I personally wouldn't be interested.
And I'm very much attentive to tire pressure.
Maybe I'm just stuck in my old ways and late for the train. (?)

I just got my Accu Gage meter back from G.H. Meiser & Co. - to be accuratized.
They generously attached a new hose w/swivel and a new pressure stop valve.
Free of charge - $13 for shipping both ways.

Thought I'd share.

Do you motorbike guys use nitrogen in your tires. It doesn't change pressure when temperatures go up and down. It's heavier than air though.

Nitrogen does change pressure when the temperature goes up and down. 1 psi for every 10°F.
Nitrogen will also leak out of your tires like normal air does, but at about 1/3 the rate.

The advantage of Nitrogen in racing is the pressure gains/losses are more predictable. Mostly because when filling with Nitrogen it is drier. It isn't effected by the humidity at the time you are filling like compressed air. The more humidity in the compressed air the more pressure will change with temperature. But still not a lot. Talked to the F1 tire compound guy at Bridgestone. He says street compounds you can change the pressure plus or minus 3 degrees without effecting the handling. Said in F1 a difference of as much as 1/4 degree can change the tires grip and handling.

Compressed air for filling tires is a lot more available. And doesn't cost nearly as much.

I do know if the front is pushing and I'm using my knee to stop it, or the rear is spinning up more than every one else, I might need to let a pound or two out...

Yeah...having a sense that tire pressure is a bit off on either end is similar to fine tuning one's sense of various suspension settings - something that took a long time for me to decipher and learn.

If I leave the house and don't ck. tire pressure and my front is down just a tad, I'll feel it at my first left turn.
In fact, I'm in the habit of taking that first left turn (a few blocks away) intentionally hard in order to check out my front.
And if the front is down a bit the bike will give an ever so slight inclination to dive in.
Some tires give better feedback than others, of course.

To me, that's a lot of what moto riding is about. That intimate, subtle sensuous feel...that relationship with the machine and its components.
