Mystery Forks

Hi All, A few years back I purchased an R65/7 frankenbike with the intention of turning into a cafe racer. Then along came kid number one and I mothballed it till now. I am going over the bike and putting a parts list together so that I can finally start bringing it back to life and finishing the project. But I am having a hard time identifying what kind of forks and discs were used on the bike. I heard they are from a K bike, but that is all I know. For now just going to clean them up, they worked great when I was riding the bike. But the discs look like they are not long for this world and I know from a past once over that they are not thick enough to be turned.

Here is a photo

I was hoping someone out there can identify them. Thanks for the help!

Well, that would explain why I cannot find a K bike front end that matches it... Thanks!

Yes, they look like stock forks for an 78-80 R65 with the stock ATE caliper.

Not much of a mystery after all. Those are stock.

The dual disc was an option on the R65. I have no idea how many were ordered ... but it was an easy add-on. The second slider already had the brake mount.

It is an R65LS frame with a R100/7 engine, but with R90 heads. Or so I have been told. Same person said the forks where from a K bike soooo, gonna check on that as well. Going over it trying to identify all the various bits and pieces. Most of what I read was that the R65LS came with dual Brembos, but apparently some of the first LS models had dual ATEs instead.

Anyhow, thanks for the help! New to the forum and fairly new to airheads as well, so I will probably be on here often asking stupid questions.

The original ATE caliper on the R65 looked remarkably like the later Brembo. The ATE Caliper in this pic is one of those ... The R65 came with this type from 78 to 80 IIRC ... 81 and on BMW switched to the Brembos for everything.

Edit: Here's the original ATE that is one the R65 (See the ATE in cursive on it?):


And here is the Brembo:
