We’ve got a bit of a thing for Moto Guzzi here, and this vintage racing motorcycle from Japan has got to be one of the best Guzzis in the world. We first noticed it in September but now owner Shiro Nakajima of Ritmo Sereno has released more pictures and information about his personal bike. The engine is running an increased compression ratio with polished and ported heads, Carrillo rods, titanium valves and a balanced crankshaft. Numerous smaller mods include a new oil filter system, an aluminum flywheel and a new steering bracket. Handling is taken care of by Öhlins suspension, with AP Racing brake calipers bringing the whole shebang to a stop. It’s hard to believe that this machine was originally a rusted-out wreck that Nakajima discovered “partially buried in the desert of Arizona”. Right now, if I had to pick one vintage motorcycle in the world to put in my garage, this Moto Guzzi would be it. Check out the Ritmo Sereno website for pictures and specs—plus videos of the bike in action.
