Acceptable loss in tire pressure

Since I only get to ride a couple of time a month, the bike sits for weeks between rides. The other day I jumped on it for a short ride and noticed it handling very strange. When I got home I found that the front tire was down 10 PSI. So today I was at the dealer and asked the service department why I would be losing tire pressure on a brand new bike. I was told that a 2 to 4 PSI loss per week is normal. This seems odd to me since I have never experienced this with any of my other bikes.


Have any of you guys had a similar experience with tires deflating this quickly?

Sounds like a normal answer from someone at a dealer.
I think they teach them to give some answer so it sounds like they know what they are talking about.
2-4 #s a week is absurd. I’ve left mine sitting as long as you in winter and never lost that much.

Ridiculous! I top off the tires in December and by spring I have to let out some are because the relative pressure based on atmosphere has increased.

First. You should not have ridden without checking pressure.

Second. 10 lbs in a couple weeks would have me spraying the tire with a soapy water mix to check for air bubbles escaping from the tire, valve stem, and bead.

Find a new service tech.

there's really not much the dealer can do about it.
don't think you want to pay him for that anyway.
make it a habit to check them if the bike sits a week or three

The dealer is full of it. If you’re loosing 10 pounds, check your valve stem for a slow leak.

Could a family member be messing with you? My sister was letting out 5 psi from the same tire on her exhubands truck for over a year he never was able to fix the leaking tire. She never told anyone until years after the divorce.

Checked mine yesterday, down .5 front and rear over a 4 week period. I think that is more the norm.

Sounds like more dealership propaganda.

Temperature goes down, the pressure will go down. Temperature goes up, the pressure will go up. I see you're in FL like me (a bit further south). In the Spring, the temps were all over the place. If you filled the tires on a warmer day, then a few weeks later when you checked, the temp had gone down, expect the pressure to have gone down.

After I cupped the tires on my first heavy bike (Ultra Limited), they told me to check the pressure every week or two. I do this now because tires are expensive. Prior I had been checking like I would do on my truck. It was pointed out to me that the volume of air in the truck tire is much, much greater than a motorcycle tire. Loose the same volume from the truck tire, you won't see much of a change compared to loosing the same volume from the motorcycle tire.

Larry, no offense but your sister sounds like a skilled terrorist. That is some next level shenanigans she was pulling. I hope he deserved it...
