Do motorcycle tires require any special valve cores?
Or, are there any recommended cores for a 90 degree valve stem?
The ones in my wheels are not playing nice with my tire inflator.
I think they may be too short.

Ariete valve stem. Have used them for well over 10 years and only have good things to say about the. They are an angled valve stem.

I have the Ariete's and they use standard valve cores. I have had to replace one due to stripping the threads on the core. Maybe the inflator and not the core.
 
There is a valve core tool for this and you can find them in the tire repair section of auto parts stores.
 
Like FNMAG says....Ariete. The best. Many racers use them. Multi-colors. Two wheel sizes. 90 degree and 70 degree too.41WIcRO3nBL._SX355_.jpg
 
Or go to any bicycle store. Motion pro sells a very nice one for $7.50, and you can find them all over ebay for less than half that. All valve cores are the same. Well, I should clarify that a bit. There are two types of valves - Schrader and Presta (I think that's the other one). Cars and trucks and motorcycles use Schrader; Presta is the super thin one that you find on racing tires on bicycles. I'd go to a real auto parts store - one that sells to service stations (e.g. Auto Parts Wearhouse, NAPA, etc) because they have to sell products that work, unlike Auto Zone and Advance, and buy half a dozen valve cores. Pardon my bias, but the guys who work at the local A-Z and Advance parts houses seem to turn over daily, know about as much about auto parts as I know about Tasmanian politics (well, less probably) and are as helpful as a junk yard dog. Yes, I'm not being kind, but I've been frustrated at these places regularly and only go to them on Sundays and after hours. If your outlets of these stores are good, patronize them! - you could be blessed with the kind that are near me.

Consider the 'T' valve stem. You put a TPMS sensor on the top and the horizontal arm gets the air chuck for adding air. Of course, when you install these you need to break the bead so its a good idea to do this when you are replacing tires. That way you will be rebalancing the wheels anyway.
 
BTW: The ST's take a 11.3mm sized valve core on the Ariete's . The 8.3mm are usually for Ducati's & Aprilla's. The red version is a 83 degree angle 8.3mm.11.3st.jpg83degree8.3duckaugusta.jpgThe Black stem is a 11.3mm (ST version)
 
Valve core per original question. I think they are pretty universal but I have heard to get the red ones. Seriously. Maybe a little heavier duty?
They just screw in and out easily using the little tool that you can get anywhere.
 
I've never paid any attention to what valve core I needed other than to get one that looks like what came out of the stem. I've never had a core go bad.
 
I have actually had two go bad in the past few years. One on my truck, and one on my ST. I usually start my search for a slow leak there, though...I use leak detector for gas lines. Quick fix both times.
 
While you’re buying new cores, buy at least one of the metal valve caps that has the core remover built into the cap. That way, you’ll always have the tool, and it will be stored, exactly where needed.

I've added TPMS to my bikes, and now use "T" valves. These allow the TPMS sensor to be installed and still adjust pressure without removing the sensor.

Wonder why the HawksHead valves are not compatible with FOBO large sensors?
 
Should be no reason why not. Fobo sells the t-valves too. I can only think a large sensor will interfere with your brake calipers. The large Fobo sensors (for cars/trucks) are the same diameter and height as the bike ones on the Fobo site... mystery marketing? Valve cap threads are universal, so no reason they won't screw on to a t-stem.

The only reason a Hawkshead T-valve might not accept a Fobo sensor could be the length of the threads on the straight leg of the stem. Fobo has you screw a nut on first, then the sensor. The nut is then tightened against the bottom of the sensor to prevent easy removal. I've noticed on my Fobo T-valve that there is very little room between the top of the nut and the bottom of the sensor with the nut screwed all the way down. Perhaps other brands have fewer threads? This is not a mass produced item with many many manufacturers, and I would guess there are very few sources of these so this is only speculation on my part.

The FOBO fits fine on my ST - no interference with the discs or calipers.
 
Go to any tire changing store and ask for a valve core. Nothing special about a motorcycle core. They'll probably give them to you.
