That looks like a modified stock swingarm (with a brace and shock mount). I wonder how well it works -- what he did to determine the correct spring rate. I like the idea, but not so much a fan of the front end being lowered so much that the gaiters are completely compressed. And don't get me started about the Firestones!
He actually sells this monoshock setup as a kit on his website. The front end isn't actually lowered on the gaitors he compressed just the gaitors for looks. Has allot of cool cafe creations on his website " Kinetic Motorcycles " is his name. Pricey but very nice looking gear.
While that bike may look pretty, it is almost completely useless the way it is there. That front IS lowered, look at the fork tops protruding through the triple clamps, those firestone tires are plain dangerous as an all round street tire and should only be used on trailer queen show ponies, it has no front guard of fork brace. He goes to all the trouble of building an adjustable rear suspension, screws with the bikes geometry at the front by lowering it {for looks} , makes it worse by taking the fork brace off, removes the front guard so you can eat road debris as you enjoy your ride, and finishes off with the worst tires in creation...
. That bike is just another rolling contradiction, if thats what you like then great but its definitely nothing special, built for looks and would handle like a pig....
