That does look useful. Both the Speedmaster and the VStrom have spoked wheels and it’s a real pain in the bottom attaching a pump.

 

Don’t like buying anything off Fleabay. Can you get them from Halfords

That's when you use your other purchase

 

Wouldn't the pressure in the tyre remain the same once the valve extension is removed?

 

Isn't that volume rather than pressure though?

 

Wouldn't the pressure in the tyre remain the same once the valve extension is removed?

Yes, but you'd also be losing the extension tube itself, therefore the volume is less, so less air is needed to get the same pressure.
The pressure in the tyre would stay the same.

Ken, bmw have just taken exact conversions of bars to psi.

36.25 psi = 2.5 bars,

39.16 psi = 2.7 bars.

 

So if you fill your tyres with helium which is lighter do you need to put a higher pressure in to get the right amount of air in there? What's the conversion factor? If you use a long extension that might remove enough to make it correct.

 

I just fill mine with lead. Won’t leak and helps with lowering the center of gravity. The extra weight allows my mates riding Hardleys to keep up, almost.

 

Dry nitrogen is the preferred choice if you're tire temps exceed 250 f. Moisture (steam) can play havic. Recommend tire pressure Is a baseline only.. most tire pressure gauges only only 10% acurate
