It seems some shops mean riser bars by "motocross handlebars", but I am not sure. I want to buy some cheap but good looking grips, but there is a warning that they "only work on motocross handlebars", so I thought I'd ask before committing.

...are they motorcycle grips?

I don't think so: https://www.jensonusa.com/store/produ...Mc+O+Grip.aspx

oury also has different grips for motocross and watercraft,
but i saw several sources that had motocross bars marked
as 7/8" grip diameter, which is super close to 22mm. so...
i guess i can't say for sure. there is aways a chance that some
motocross bars have a different grip diameter.

motocross bar STRAIGHT 7/8" diameter

NO enlarged hump in the center for the clamp

I bet those would work since they are on a bike-site, but O'Neal does make lots of motorcycle stuff....and that disclaimer is kinda unnerving, eh?

I don't have an offroad motorcycle anymore or I'd go measure it for you, but if I recall, it was pretty close to mtb bar diameter at the grips as travsi says. Maybe you should search out some motorcycle bar specs?

any reason you don't just go with bmx grips?
they'll definitely work on risers, and you have quite a bit of selection.

maybe you should get bicycle grips

Check out ourys web site, they have motox grips as well as mountain bike grips. Also very comfy.

Be careful because motorcycle grips tend to be 7/8ths for the clutch side and bigger for the throttle side as the throttle slides onto the 7/8 bar and is clamped in place.

On a side not I just put oury's on my Vespa and they feel great!

with some bars oury's can have a maddening tendency to "twist slip", and usually at the worst possible time.
I don't own bicycles with grips OTHER than oury's, so I now use a rubber cement type spray adhesive, and let em dry overnight before riding.

GREAT grips, but I think they make them slightly oversize so they'll stretch on fat bars (or on the throttle side of a motorcycle)

Mine fit snuggly and dont slip much if at all. Oury mtb grips and used Wald risers. Used water to put them on, and let dry over a day or so. Also used the same method on revenge grips (BMX) and nasbar (DH MTB) risers, little slippage at first, but I didnt let it dry long enough.

whats it called?

my ourys have been giving me problems lately

Thanks a lot, guys, I <3 you! All three of you added an important piece to the puzzle - I now feel comfortable buying those grips.

I like the fact that they are cheap, and that they are sold by JensonUSA.com, one of the few online sellers that won't **** me with shipping charges.

if your looking for a super comfy gripy set of grips that arent the ussual road bike bar tape.. check out A company called animall and get the edwin grips.....there super gripy and as they wear in the get even better..
