Re: KUMA Magnesium Wheels

Kurt, as I remember, those mag wheel conversion kits were in the $500-600 range back around 1975-76. I never saw one installed on a bike back in the day - and I was in a pretty busy BMW area.

Re: KUMA Magnesium Wheels

Hey Jeff, thanks for the note. You see the Lester wheels quite often, but the Morris wheels that you have don’t show up quite as often. I remember Butler & Smith offered them in their accessory catalog. Share some photos if you don’t mind.

KUMA Magnesium Wheels

Does anyone have literature or other information about KUMA cast wheels for BMWs? These are a 1970s German made aftermarket accessory.

Re: Restoring #163

Thanks Eric! I hope to see the bike in person someday if BMW North America brings it out for display. Perhaps next year for the 100th Anniversary celebrations.

Re: Restoring #163

Eric, yes I think that’s a good idea - I will. Sorry if I got too far off topic answering a question to my question. We’re all learning a lot here though🙂 From the background story that your father told me, and checking specific details of the build, I am about 95% certain that I have the Fisher bik...

Re: Restoring #163

Here is a view of the magazine cover. April 1976. I have an old Butler & Smith R90S racer, and have been following Eric’s story about #163, looking for clues about mine. I’m still not certain of its exact history, and Covid has kept me from getting it in front of Eric’s father Udo for a closer look....

Re: Restoring #163

Chuck - I know that you were there racing that first year in Daytona too - Laverda, wasn’t it? Does this this reddish ring hanging around the frame have something to do with the Tech Inspection done on the bikes?

Re: Restoring #163

Hi Chuck, yes it is counterintuitive, but it works! I saw a similar setup on an NSU racer once. I’m not sure how long they used the setup, but they did use it in the very first race. Here is the April 1976 issue of Das Motorrad, which had an article about the Daytona race the month before. You can s...

Re: Restoring #163

Thanks for the photos of the original top motor mount. Mine are definitely replacements. Race bikes are always a snapshot in time! I was finally able to find a clear photograph of the clutch cable/throwout I asked about earlier. When you have time, can you see if you have any photos of how the throw...

Re: Restoring #163

Eric, do you have any close up photos or other details of the 2 top engine mounting brackets that were added to the B&S racers, and how they attach to the 4 studs that were added to the top of the engine (last two photos)? Also, I’ve seen two versions - what looks like a solid one on the restored 16...
