Why would you ask if it costs anything to convert the rear brake to a disc?

It already has a disc in the rear, you can clearly see the caliper in the photo.

Looks like a broken ankle waiting to happen to me. At least put one of the alloy racing guards on it. Better yet, nicely vented stock primary cover.

I don't get why anyone would run a unprotected primary on a street bike. It's like running velocity stacks on a carb. Looks cool but what happens if you end up in a bunch of dust ? Seems to me the Rotor / Stator would pick up magnetic junk from the road over time, water born grit, rocks & dirt will certanly get into every thing including seals & it will all wear out faster. This may be an acceptable risk for a race bike but just silly for a bike that gets ridden in the ever changing street. Why would any one do it?

I plan to be going with a covered primary, I just find the look appealing. The reason i asked about the price or the rear disc is because I dont have a MKIII. Though Im unsure if the need for a rear caliper is needed if Im not racing.

Read some of ludwig's posts on how he did his rear wheel.

You can't run an unprotected primary on a race bike....at least not in the UK!!!

Nice, nice, nice.

Open primary [dry belts duh] are a dime a dozen in chopper-bobber world and we don't here stories of limbs chewed off by riders. It look more dangerous to ride than it really is, UNLESS of course you tempt fate with lace boots over bell bottoms.
The main issue is grit getting on belt edges to fray apart and when working around it running.
Long hair musician putting head down to look at carb or such could loose some mane. Second issue is if bike ever laid on you that side running.
Mostly what happens if touching a running belt drive is you feel it bounce you off it or get a rug burn before it flings you off it.
Stick a finger of tool under a run >> though i hardly ever do anymore.
