Anyone know what the size valve hole is in the 14 rims?
I'm looking at replacing the tyre valves for right angle valves (not the adaptors!), like the OEM valves on my Triumph Tiger and Sprint, which are much easier to use, and it's looking like there's two sizes 8.4 and 11.4mm diameter :whatever:
Cheers :onya:
I carry a right angle adapter under the seat problem solved .
There is a discussion on if angled valves upset the balance if the wheel more than std valves.
:cheers:
I have 90° aluminium valves from eBay.

Also, looked in old purchase confirmation - they were 11.3mm
Sorry don't like them. I carry an adapter.

Can't see why that would be the case seth - they don't cause any balance problems on Triumphs or other bikes they are fitted to, so don't see why they should be an issue on a 14. I have them on my Triumph with the adaptors on for Tyre Pressure Monitoring, and even with those as an addition, still no problems.
Carrying an adaptor is fine, however, you will always lose some air when fitted and removing it, can't be avoided.
But everyone to their own, if I still had my 14, I'd fit the angled adaptors as getting to the front tyre valve was an absolute nightmare, to me angled adaptors are so much easier, but like I say everyone to their own
Pretty sure
@Bov fitted right angle valves to the bike when he had it. At any rate I have them there now and they have never caused any issues with balancing wheels or in use.
I can only imagine the pain of airing up on a 1400 without them. These make it easy.
Unfortunately I've no idea of the brand of these ones, but I'd recommend you buy the best quality ones you can buy as opposed to the cheapest.
See if the place you get your tyres done sells them and get a set put in next time you have the tyres changed.
Got a set installed 2 sets of tyres ago - they make life so much easier and I'm at a loss to explain why it took me so long... :doh:
I still have the right-angle adaptor in my jacket pocket - comes in useful at the servo when someone else needs it!
:cheers:
I had them on a modded Hayabusa.
Twice I ran it flat out in top,
both times I lost a lot of pressure in the tyres.
Probably not an issue on my GSX1400 though... :rofl2:
I check my tyres at home before most rides but I'm a great believer in a compressor under the bench and a digital tyre gauge. I have a few airlines but use a rubber flexible one on the bikes. Compressors is always hand for other jobs too. Very rarely ever use those servo airlines.
Getting a compressor is on my wish list too, if I ever have some $.

Yes, they're the ones I'm looking for. Thanks! :onya:
I've noticed the valve on the front has cracks around it's base (the body is rubber). So I need to replace it pretty quickly! Obviously the wheel will need re balancing, but then it'll need re-balancing, or at least checking what ever valve I put back.
I've never had any problems with the right angle valves on my Triumphs, so that's what I'm going for.
I had them fitted (Pointed to the right) when I first got the bike.
Not lost a single pound of pressure in 9 months!!
Have them pointed to the right so you dont crap your hands on the chain... Also when on the side stand its a bit friendlier to use.
I would difinitely have them fitted again.
As for balancing..
Have the wheel balanced after they are fitted.
One of the better mods for motorcycles in my opinion.
I use right angle valves for years with no problems. Good "mod" for me.
E: About balancing. You will not even recognize the rear wheel when it's unbalanced at all. The front is the need to balance but not the rear. On track rear wheel normally does not balance...
Last tyre change I had these put on & wish I done it earlier.
Also grabbed a great little portable dual powered compressor from Bunnings for under $100, which has made life so much easier & convenient.

Grab one of these Vlad, if it's just for small stuff. Cheap & very handy.

@seth Mate, balance cant be an issue (or at least serious issue), in case using those light aluminium valves. They are so light (5-10g) and gap in wheel seems to be bigger then they are. Also, tires may wear unequally, and they could cause more unbalance then those valves will ever do.
But I totally support your solution - everybody chose their own solution :cheers:
@northern They look great
I remember reading that due to vibration and being shaken on the wheel as they are not inline with other forces on the wheel in all plains.
the seal can fail at higher mileages especially if they are not replaced at each tyre change.
They would make checking or topping up of tyre pressures easier.
As you say each to their own
I was just showing there are downsides aswell as your plus's.
:cheers:
have a set on my wheels and change tires and had no probs with them no vibrations only thing is the cap pain in the arse they seem to wont to cross thread as the are ally ones so be carful screwing them back on but so great at the garage air guns you can use them but if you have a right angle adaptor and carry it on the bike problem solved which I have under the seat as my mates on rides never seem to carry one ebay £5 or the longer rubber one with the clip lock £15
I swapped my ally valve caps for placky ones..
Bought the Ariete Bridgeport ones angled at 83 degrees and 11,3 mm hole. Only 12 grams and most of the weight is centered in the base, don´t see how they can influence balance.
With the greatest respect to Seth I cannot see how my angled valves would flex and become unseated.
they are a rock solid fit into the wheels rim with ZERO flex available on the valve.
I have no intention of having them replaced at the time of tyre changes!
They flex because the valve body isn't inline with where they mount in the rim. If you pushed down really hard on the end you'd imagine the far side of it in the rim would start to peal up, that's what happens at speed due to centripetal force. It may never cause an issue but it will happen.
sure did to me. tyre went flat very quick.just on 100kph and full side to side. werent very old at all. opposite side of where valve hangs out was split at rim. mine were only rubber, not metal. scared me off from any others, just use straight now. have a right angle thingo under seat, i find it a pain to use. my pump has straight fitting, rubber hose, easy to get hand in to pump, then just use digital guage to let down to pressure. just my way.
@Speedy1959 I knew I'd seen stories like
@grog's before and cheers
@Hooli I'm not saying don't use them just be aware of the risks involved.
:cheers:
To put this in context, there are no risks if you use angled metal valves, the risks are only with plastic or rubber angled valves which can rip out.
i agree Barmy. only ones to use. i thought rubber was ok, not at all. one of my scariest moments on a bike. instant deflation.
Instant tyre deflation is interesting.., I once ripped a hole about 1" square out the centre of a rear tyrewhile doing about 90-100mph. That felt odd as I slowed & every time I went below 80 it sat on the rim & followed the camber no matter what I did. I'm damn glad that was a straight road.
I've finally got around to ordering a pair of the black 11.3mm Bridgeport angled tyre valves as I've got a tyre change coming up very soon.
I got this pair from ebay for £15.98 delivered.

The type that you DO NOT want to leave attached to your rubber valves and ride with are the gold screw on type. The centrifugal force will break or rip the rubber valve out of the rim resulting in instant deflation of the tyre..Which isn't nice!!
I fitted them many years ago and got home from a ride to find the front rubber tyre valve partly out of the rim..I was very lucky!
Make sure when you have them fitted that they point to the right side of the bike as you sit on it..Makes for easy inflation when the bike is on the side stand.
Black good...Gold only for temp attachment while inflating tyre.
PS. I've had them on my Bandit for years now and they are spot on..Look good too :onya:
