I've got an '81 standard R65 with ATE calipers .
In early 2007 I decided the bike needed some work done to it .
Had about 87,000 miles on it without much done other than routine maintenance performed .
Front rotors for replacement as well as pads .
I went to the EBC website and found rotors and pads effective for '81-84 R65's .
When I got the parts they weren't the correct parts .
The rotors were for composite wheels not snowflake wheels.
The pads were for Brembo calipers not ATE caliper.
You can alter pads for Brembo's to work on ATE calipers .
BMW used ATE calipers into the '82 model year until they used all of remaining stock of parts .
Sometimes even the parts catalog gets it wrong !!
