It's another seal that fits into the hub to cover the bearings.

Not Quite Correct Katoom
I'm happy to talk about this, although its probably not of much interest to many.
The WPB Stomp Sealed bearing are not just an external seal, but actually a machined bearing and a matching machined wheel spacer that sits deeper than the normal face contact of a standard bearing. They are stepped, you get a better seal that way and also the spindle/axle is more firm, relying less on a tight spindle wheel nut to stay firm. Front and rear wheel of course, and the rear wheel, is obviously where this is of great advantage.
You Don't get them offered to you from the generic Chinese pitbike parts factorys.
Having clarified one of the actual differences in what everyone says are all the same bikes you can make a choice, but actually not all crf70 main frames and subframes are the same either, but thats another story.
WPB and Styomp have taken what appears to be a generic crf70 bike and engine and actually made a difference to what the factory normally push to the buyer.
