Had a good question emailed to me on what is suitable proof of a machines eligibility for whatever class.
This scan of a "Two Wheels" magazine from May 1974 page four (part page in attached photo I think) I used as proof for my Honda 754 sidecar. Anyone else like to post some good examples for all maybe use as examples in their own quests?
http://ozvmx.com/images/forum/tw-sc1.jpg The pictured sidecar is a "SSP' oops...in meant "SPP" make ,running a K series 754. Lucky Walter of YSS fame was there at the time and can still remember the screaming howl of the 4 cylinder beast working hard and fast. What a fantastic mixture of big heavy makes and models competing.
I have amended this post as ,,well the grammar and syntax was pretty awful!!
