The mere mention of the word "Safety issue"   can open up a complete can of worms. Most of these old jiggers are way past there use by date and would be riddled with stress fractures in thier frame members - swing arms  and brake components.

Yes you could be right.  However you can buy most parts for Maicos as reproduction items.  (frames, swingarms, wheels, forks etc).  So for safety reasons everyone should be racing Maicos.  But what would be the fun in that.  Just another side note.  You can build a Manx Norton from brand new parts and most of the cars in the Touring Car Masters are complete rebuilds with new parts.

Also most riders aren't riding/racing their bikes at the speeds they did when they were new.

Also some irony in the fact that  because nearly all original rear shocks are rooted or not rebuildable , we  use repro and  external  rebound and comp clickers are allowable (for safety!!)

So Applying that logic repro. forks  with external  & adjustable  clickers should fine!!!

Yet  non adjustable forks   ie it250k/490) that came off a bike that wasn't non linkage are not legal .....!!! Hmmm!!

Makes those fox forx and yz465H a pretty valuable commodity, maybe we  need repro. fox forx with clickers too!(for extra safety!!)

 
anyway good luck selling the TLS backing plate!!

The plates will fit the 465 wheel but not the forks, I bought a 490 backplate to raid some parts off for my 465h & everything is a straight swap apart from the hole for connecting the brake cable is smaller on the aluminum arm
