Here are some motorcycle specifications. The first part is just a bunch of general specifications. These are the sizes of chains, batterys, tires, spark plugs, and the like, for current model motorcycles (1970-2001). Then, as I get the time, I'm going to add more and more specs on different bikes. I'll start with specs on bike that you might run across, but will have a hard time getting Info on. Like 1960's and 70's Japanese bikes, and grow from there. Enjoy!
Here is a Zip file with 23 PDF files in it. With this you can easily download and print out 23 pages of general Motorcycle Specs for the years 1968 through 2003 similar to the above Specs.
