White Brothers aluminum swing arm. Now, this is a super rare piece of kit. It is about 1 inch longer than the stock arm and does not have a chain tensioner.
Ohlins monoshock. Here is what it looked like when it came back from the Ohlins factory after rebuild.
I added a Honda 1982 43mm Kayaba fork to the front to replace the ... Simons the bike came with.
Trick exhaust header from White Bros also. Only ever saw one other of these.
I also put a neat Supertrapp muffler, and a K&N filter.
It was a bit of a mess when I got it though, in particular the electrics were cooked, the magneto rotor was damaged and the cylinder had a weld repair from a hole made by a poorly tightened cam chain. The frame has been sawed off at the back, but luckily the piece had been kept safe. A lot of work, but it turned out to be well worth it.
