GasGas motard

[IDAHOSPUD]

So i am kind of interested in getting some motard wheels for my gasgas. I have done some searching but im not coming up with much in the "how to" category.

Let me ask some questions:

Can you use the stock hubs, just laced up with 17 inch rims?

How does one handle the brake rotors front and back?

Is there a kit to relocate the calipers for the larger rotors?

Sound like you can use other rims, but its lots of work to mod the rims for the spacing and the chain alignment, is that true?

It seems like most of this stuff is kind of hard to find used, on either the parts forum or ebay, is that true?

What about buying this stuff new. expensive?

In short, what is the cheapest best way to do this?

My gut tells me, find the gasgas hubs used, lace up with new rims,

Also, what is the cush hub that is needed on the rear wheel?
