Technical Information & Links: We are attempting to create a comprehensive library of documents and technical information, provided as a free resource for persons interested in Russian motorcycles. All documents, videos and other files listed here retain the copyrights of their individual owners and are for personal, non-commercial use only. This library is being updated regularly: if you would like to submit a relative document for inclusion please contact me.
All the information presented here comes from other sources, and there are no guarantees that it's correct:
I verify things as I can but common sense should prevail.
Personal thanks out to JD at bCozz and John van Ierland for their work in scanning many of these documents.

| Again, this is and will remain a free resource. But I'm not above accepting donations to help cover hosting and maintenance costs. If you have a couple of bucks, euro, dinar or free range chickens to spare you can direct them towards a good cause here: |
