Air hoses that frustrate some riders

Riders with spoked wheels on their bikes are frustrated at not being able to get some service station air hoses to fit their metal valve stems.

The owner of a Queensland service station says he suspects one rider became so frustrated he found a solution to the problem by bending their air hose nozzle.

“I’ve often seen riders struggling to get the nozzle on to the valve stem on motorcycles,” the servo owner says.

“I suppose this works better now because of the angle, but I’m surprised he didn’t break it as it’s only made of brass.”

Riders should be aware that service stations are not legally bound to provide the free air service. Some have chosen to withdraw the service because of vandalism and accidental breakage.

Air your grievance

Air hoses are made to suit cars with flexible valve stems. They don’t suit all types of motorcycle wheels.

Riders with mag wheels on their bikes can start laughing now …

However, it’s no laughing matter for some riders with spoked wheels on their bikes.

In fact, it can be downright infuriating.  On several occasions I’ve ridden to several service stations in search of a hose that will fit.

The worst offenders are the old-style air hoses with the pressure indicator on the air hose. These have a long metal nozzle which is at the wrong angle to fit on the rigid metal valve stem of spoked wheels.air hoses tyre pressure gauge

But even some of those are too stiff to bend enough to fit over the perpendicular valve stem.

Most spoked-wheeled bikes only have one disc brake on the left of the front wheel so you access the valve stem from the right. But even these can be difficult to get an old-style air hose to fit.

If your bike has dual front discs like the Ducati GT1000 I once owned or the Triumph Scrambler 1200 I tested recently, it is almost impossible to fit any type of air hose.

Some bikes with spoked wheels have large holes in the wheel hub so you can thread the air hose through the middle to access the valve stem in a straight line.

Otherwise, you have to thread the hose through the spokes wheels and even then it can be a difficult angle.

I’ve copped bloodied knuckles trying to get the right connection on the valve stem.

Meanwhile, as you try fitting it, the connector triggers the valve and lets out precious air pressure.

After struggling in vain, I’ve sometimes left servos with less pressure in my tyres!

L-shaped valves

Replacement L-shaped valve stem

Apart from the vandal’s less-than-ideal solution, you can fit L-shaped valve stems to your wheels for easy access by any style of air hose.

I swapped the very heavy spoked wheels of the Ducati for beautiful, lightweight Blackstone TEK carbon fibre wheels which came with convenient L-shaped valve stems.

It’s surprising bikes with spoked wheels don’t come from the factory with these right-angle stems.

You can buy L-shaped stem replacements for a few dollars or about $25 fitted.

However, make sure the tyre fitter re-balances the wheel after they are fitted because the stems can have a slight affect on balance that could lead to handling problems.

Even a minor variation in rotating weight can lead to dangerous vibrations.

A cheaper option is to buy an L-shaped valve stem adaptor that screws on to your valve stem. They are small enough to fit in your pocket and only cost a few dollars.
