Right angle tyre valves

Dusty ST · Monday, 09 July 2018, 06:18 AM

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

Cheers

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.

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...

I still have the right-angle adaptor in my jacket pocket - comes in useful at the servo when someone else needs it!

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...

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!

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
