Hi,

I was reading up on driveshafts and came across this on Aliexpress. Screenshot 2025-11-16 at 15.41.59.png

I am assuming that BMW have these made in China in high quantities and that this is the later shaft that they replace for free... hence the price of this one in the picture

The part ...

I've looked back at the spec of a 2011 RT. Bloody had to find on YT and Google, but it seems all versions of the RT in Europe and the US were fitted with an ambient air temperature sensor as standard on all bikes.
The sensor is not connected to any other device on the bike, so it is totally ...

Thank you for that information ... as long as its absence does not have an effect on the ECU

I have the right side of the bike stripped and it is nowhere to be seen ...

Is the air sensor required by the ECU ? Or is it just for ambient temp indication ?

I know my bike had an engine swap recently ( before I bought it ) so I am going over the whole bike checking and torquing bolts.

So far ...

Hello,

There does not appear to be an Ambient Air Temp Sensor fitted to my bike ( 2010 R1200RT )

Are thy fitted to all models ?

Thanks

When I told a Kawasaki-riding mate that I’d moved from a Pan to the RT he said “I don’t know if I can talk to you anymore then…”
I looked at him expecting to see a grin, but he appeared to be serious… not seen or heard from him since.
Some people are very strange.


Strange indeed ...

I could ...

Are they friendly ?

Every time I tell someone that I have bought a BMW the general response is 'Oooo your gone over to the Dark Side !"

I will get the code off the engine tomorrow and have a poke around the internet ...

Couldn't tel you where my nearest dealer is ..

Hello,

Does anyone know if there is a way of tracing the engine number of an R1200RT ?

I ask because the bike I have had the engine replaced due to a drop.

The bike shows 31k miles and the engine apparently has 21k on it.

Im just interested to know where and what bike it came from and better ...

Thanks
