You could make your own two peice sprocket.

just need an angle grinder what if it let go would cause some major damage I would think.

I'd forgotten about them. 
They were a Sidewinder thing, weren't they?

    I believe it was a concept originally designed to defeat time-consuming ratio changes for final-drive applications, like removing the rear axle of an early quad, trike or more to the point of origin, “an industrial application”. I know I have been accused more than once of leaving my brain in the tool box, but why would any body consider increased sprocket component manufacturing costs and fitting hassles of one of them onto a motorcycle. Better suited to early quads trikes and heavy industry applications that require ratio change or quick chain and sprocket replacement without requirering massive and needless loss of production time, by dismantling the entire machine or rear axle off some quads or trikes.   
Cheers, Mick.

Why didnt RM use the quick rear wheel setup like a PE?

Hi Michael,
                   Because the PE is an enduro bike that requires a “quick change” design.
An RM is a ballistic motocross machine whoose suspension performance benefits more from a lesser unsprung mass(weight) and whoose owner does not have to compete in a timed tyre change test as a part of an enduro event.
Cheers, Mick.

Ok thanks Mick I wouldnt have thought there would be much weight difference in it because that is obviously what they want to acheive with the 2 peice rear sproket thanks, Michael.

Superkarts use split rear sprockets, nothing new there
