You can buy just the brake system (master cylinder/brake line/caliper w/E6 bracket) for $155.00
The rest of our kit is a billet hub with spokes so you can build a wheel and the 180mm Galfer rotor.
If you can find a Marzocchi type front wheel and a 180mm rotor elsewhere, you'll be good to go.
You will need to make wheel spacers for the Mazocchi wheel on the E6's.
