Tyres, Brakes and Suspension » Misreading on the front tire pressure sensor

My front tyre pressure sensor reads 2,7 bar when there is 2,5 bar in the tire. I have checked with several high quality pressure gauges.
Rear tire sensor is spot on.
Can the the sensor be "re-calibrated" somehow ??

I made the mistake of adjusting the cold tyre pressures to the sensor readings. The result was a bike that wallowed two-up and handling that was a little vague.
Discovered this when the bike was dealer serviced, had higher sensor readings but handled so much better.
I now set the tyres up cold with a foot pump and separate gauge. 2.5 bar front reads 2.7 on the sensor and 2.9 rear reads 3 2 on the sensor. The readings vary a little but that's a reasonable indication.

You're right. My brother found the sensors on his GS very handy when he got punctures. Two in three months poor bugger.

This thread prompted me to read the manual again. I was trying to figure out why I thought they were a reliable indicator for cold pressures. The manual is clear about the temperature compensation but doesn't join up the dots - which would have been helpful for a dotard like me. To compound matters however, there is a section which explains how to use the RDC readings to compensate for erroneous readings from an air line gauge. If you follow the advice, you'll be 0.2 - 0.3 bar under the recommended tyre pressure. Inside the permissible tolerance perhaps but riding a wobbly camel. If you're gonna top up while on the move, I'd suggest using the observed RDC values when you know the pressures were correct cold (in my case 2.7 -2.8 front) instead. Could be useful on an extended tour when you don't have access to your usual tools.

Flippin eck, that's true. My mrs is laughing at me as once again I've disappeared up my own arse with details that don't matter. In my defence I've had pencil gauges long enough for them to go out of sync so I now have a dual check system when checking pressures. There's no denying the fundamental logic of your post and instead an uncomfortable realisation that I'm turning into my Dad. Holy shit, how did I get here?

Guess which one I was carrying on the bike when dealing with last week’s puncture?

And there’s another 2 outside in the car glove boxes.

Like most tools - you can never have too many.

The dash display is for entertainment

I’m happy that my 2 favourite gauges agree with each other.

Set cold.

Ignore dash reading - until it drops to zero.

Ride happily ever after.
