We will see how hard this is

Few specs/pics:


From Vintage Brake:
Yamaha XS650: 200mm 2LS, 35mm wide, 17mm axle, 36 hole, good pre-holed hub and scooped backplate, swap bearings for 20 or 25mm axle, lug mount. 3 things not to like: wimpy 6mm link rod in compression, master and slave arms work through different leverage ratios, actuating cams do not locate shoes.
