Butch, another common wear item you may want in your list are the wheel bearings. I had made a post with some various bearing and seal options HERE if you wanted to review and add any of that to your list.

Don’t forget to top off the roost tank. Some riders go through copious amounts of roost during a ride, especially off of the starting line. (Just ask whoever is following @Fog 25). Don’t run low on roost or the other guys will think you are on a regular gas bike and have to do pansy stuff like shifting. A constant stream of painful roost chunkage slamming into their vulnerable frontal areas will keep your foes far behind, and your friends farther. Stock up on old favorites like “dirt clod” and “pea gravel” or “stinging sand.” Just make sure it is all rated for industry standard Map 4 Roost output velocity. Some people prefer extra chunky style over smooth & stingy, but that is just rider preference.

I wood be be happy to put the meat of this iin the first post, but modpowers have I not.


wheel bearing replacement. There was a previous discussion on the front bearings (edit ) Replacement wheel bearing kits .

"Several members have had what I would consider premature wheel bearing failures now, the causes are debatable, but this information should help for sourcing the replacement parts.

Here are the numbers for the All Balls kits courtesy of @OneLapper . The Alta uses the same rear bearings as KTM's with the smaller 20mm axle OD.
All Balls Rear Wheel Bearing Kit
All Balls Front Wheel Bearing Kit

These following bearing kits features Italian SKF bearings and seals. It also includes new hard anodized spacers which should perform significantly better than the OEM Alta/Warp 9 wheel spacers, unfortunately only the rear spacers are the same as KTM and can be used. The front spacers would not work for a stock Alta.
Inntech Rear Wheel Bearing and Seal Kits featuring SKF components
Inntech Front Wheel Bearing and Seal Kits featuring SKF components

The SKF seals in the Inntech kit have a floating outer seal that should drastically reduce grooving in the wheel spacers.

If you would like to source the SKF bearings and seals separately, here are the numbers;
SKF Rear Wheel Bearing for Altas
SKF Front Wheel Bearing for Altas

The rear wheel seals have an SKF # of WS108 and the front WS109, but I can't seem to find any web links for products, so more digging would be required to source those separately.

Hope this helps you all in the future."

@Butch , did you mean to put links or part numbers in your post above? Not sure if they came through correctly or not.

Can anyone ID the…

Front brake rotor for a 2018 EX? Anyone know the part number for the presumably KTM thingy? When converting my EX to a SMEXy thing the rotor I got was a little bit out o true…

and my goodness the SMEX is fun. Pretty impractical, but hey, bigfun.
