Just got this today! Of course it is pouring rain.... Plans call for Brooks style seat and maybe some different handle bars. The bike has a Nexus 3spd rear hub and 24x3 tires. I didn't notice it before, but it also has a skiptooth front sprocket.
One of my top 10 favorite customs. The engine is actually based on a CB550! How cool is that. Cook Customs of Milwaukee is responsible for this master piece.
