New to Me Bike Day

[Kirbo40]

  Finally found a replacement bike for my 2017 RT. Can read about that one here

 Got a 2023 RT:

Added some things:

 The rack for the Givi took some fiddling to get it to fit. This was a universal kit. Used the Admore kit for Brake/tail/turnsignal lights. Th Heed bars weren't too hard to install.

Couple more pics. 7162 miles on her.

23 mpg?   You must be really enjoying that Shift Cam!   

 

Great looking bike.   Congrats.

Very, very nice. Looks good in that shade of blue.

100% agree!  I love that blue!

Congrats on your new bike, many happy (s)miles! Try the BMW Connected App, it really does work.

I thank you all for the kind words. Those aren't my numbers on the TFT. Haven't ridden enough to change them. I have a ? tho. Does this thang have a gas gauge? And if so how do you make it display all the time? I did not get any kind of manuals with the bike. Have looked at and downloaded the manual from BMW, but I did not go over too carefully - guess I'll read some more.

[Bernie]

The manual is online, if you study it you can select what data displays in the top of the main display, above the blue-green word showing you which riding/engine mode you selected. You can use the up button on the left hand grip to scroll through this data. I always display my tire pressure, since the fuel gauge will appear automatically when the fuel level reaches reserve. It will also display your distance to empty.

Thanks Bernie I found it. Lot a learning to do here. I am from the pre-tech generation before everyone had a super computer in their hand.But I am learning to be somewhat tech savvy.

I always have it on 'range'. If one of your tires get just a few psi below normal, you'd get a giant warning hard to ignore, so no need to have them shown all the time. Plus BMW's weird system doesn't change pressures as tires heat up anyway, so it's kind of pointless to keep them there all the time IMO, but to each his own, of course. That's why you have several settings to choose from. Enjoy your new bike.

• Looks like my '23 RT, including the Heed Bars.  I don't have the trunk, but I do have a soft tail pak that I  used on trips.  Once you get used to it, you may find the seat unbearable, as I did.  Call Seth Lamb, he is great to work with and the seat is like a cloud compared to the stock unit.

That's not my experience. Both '17 RT and '18 1600B show increased pressure as tire warms up. Is this something for the new(er) bikes?

 

Edit to add: Per the manual , the pressures shown on the dash adjust to an assumed ambient temp of 68* but the pressure still rises and falls relative to the heat of the tire. This is important to know when using a filling station air source apparently. (I left for work this morning on the 1600B with 41/42 front /rear tire pressure. When I got to work 30 minutes later both read 43 lbs.)

 

I don't understand the need for the compensation.

BMW's pressure sensors have always been temperature-compensated. I don't see much rise when the tire warms up on my GS, but noticeably so on my truck.

But you are right, for everyday situations the pressure rise due to temperature is not all that significant.

Air in a pressurized tire is not an ideal gas, but for simplicity's sake let's adopt the ideal gas equation: p*v=n*R*T.

p is pressure and T is temperature (in Kelvin). So pressure rises linearly with temperature. But 68F=293K, and say the tire heats up to 120F=322K, the pressure rise is only 322/293, or about 10%. So a few psi at best.

 

It's different when you're on the racetrack and your tires can get to more than 200F.

Without temperature compensation the low-tire-pressure warning system is not reliable under some situations.

That makes sense. (TY)

Well, all of my previous (and current) BMW bikes have never done that, and I live in the freaking desert. On my vehicles, pressures increase 1 to 2 psi right away, and about 5 to 6 on the highway. And they're always off by 2 psi, not 4. I also don't understand their compensation algorithm, which is crap IMO. The pressure always reads about 4 low vs my calibrated gauge, be it winter or summer (with only a few tenths of change), so the 20C (68F) compensation logic makes no sense to me. Therefore, I cannot get the rear tire any lower than 40, or I might get a low pressure warning at real 38. The front warning goes off at real 34. I confirmed last week that my TPMS sensors work by 'waking up' the sensors after airing the tires to exactly 36/40, with temp showing 72F in the garage, and they showed around 31.9 and 36.1, so around the same 4 psi off they always do. But I honestly don't care, since I don't track the bike, and it handles well with 36/40 even at full lean, so all is well. I just want TPMS to alert me of low tire pressure, which it'd do with just 2 psi low, so that's great.

Congratulations .  FYI your not far from me if you need services , and timing check . Located in Sugar land , and have all the shift cam BMW tools ;)
