This is my Classic Kawasaki KZ400. I am the third owner of this motorcycle. It's all original. I even got classic tags for it. The crash bars from KG Engineering in Woonsocket, R. I. They are real nice on long trips because they give you a different place to rest your feet. OOPS, they call them engine guards now days. The original mufflers rusted so I bought these from J. C. Whitney. They fit so well that if I didn't tell you, you probably wouldn't know it. At 12,000 miles, it was time for it's first set of new tires. The bike has over 21,000 miles it now. Its a great little bike that is just perfect for one up riding and scooting around. When going two up, I usually take my Harley. Check out my new Sigma Sport BC800 Cycle Computer!
