83 vs 90 deg. valve stem

90 comes stock on the gen 5. If there was really a chance of failure there's no way a manufacturer would install them.

lol I was sure it was just my OCD working away on me!

Yet another reason to get a Gen5! The straight valve stems on my 4th gen suuuuuck!

I have black MOTO-D 90% stems on my bikes....Plus I love there coolmax undersuit.

Love the 90's on my past bikes, never heard of the 83's myself. (0's are great and help a lot with tire pressure adjustments!

I'd get an angle less than 90, as it will be easier to hook gauges and air pumps too. That being said, i have 90's on my gsxs1000 and gen 5. Moto-d makes nice stuff. Just make sure they are metal and not plastic on the nut/ threads that attach to the rim. I have used bike master without issue as well from cycle gear.

Neat side note: Any sort of land speed sanctioning body requires metal valve stems on all bikes... 83/90 degree ones are ok by the rules thus far.

Just use the regular stems. Kawa has a stupid cotter key in the axle nut. End of story.

I use 90's but have them facing uphill when the bike is on side stand, there so much easier to get too :nerd:

Got the 83's. Never paid attention enough to know there was a real difference to be honest. Got mine here...

The 83deg ones are the best. As mentioned, it makes it easier to air up by making it easier to connect the inflator. I'd rather have 83 deg valve than the 90 deg ones on my gen 5. I'll probably swap them at some point.:wink:

Cant comment on the 83's.... but I have ran the 90's on my track bikes for years with no issues.......

Dang...decisions. Hmmm. Thanks for all the replies! The Moto-D seems to have a nicer finish, not that ive seen either of them in person but they are only offered in 90. Will probably spring for the 83's since it does seem like it'd be easier to get a chuck on there or whatever - makes sense to me anyway. Probly cant go wrong with Bridgeport im sure even though the finish looks like yuk.

@ Blink, ill check out their undersuit stuff.

Man you guys will spend money on anything :lol:

No matter what type of valve stem is on the bike or how hard it was to access even with tire warmers, it has never been such an inconvenience that I thought I needed to fix the problem and I check tire pressures a dozen times per day on each bike...

I will spend money on items that makes things easier for me, crazy huh?!

I will sadly admit I am not a tire pressure checking artist, so the 180 degree stems can be a bit annoying.

I will also happily admit I have wasted money on parts that I thought would make something easier (a lot of which was on my honda grom stunt bike) when in fact it made things harder or no difference at all.

:idea: I guess what I am saying is that somethings people might find helpful you may not, and also the other way around and everything in between. That's the fun part about it all.

That's fair enough. Since you are so into the sport that you want to check your hot pressures fresh of the track I am sure you already have a full aftermarket suspension package on the bike right?
:grin2:


For the record I am just jealous as I don't have $29 to spend on them. Every extra dime I get goes towards tools or parts for the suspension business...
