Cb750 front brake disc
« on: January 15, 2021, 07:42:47 PM »
Hi, can anybody identify the brake disc below from the markings. It’s fitted to my Rickman and I need a replacement. Also, what model discs are interchangeable with the same offset from mounting face to disc surface. Thanks steve

Size is a better identifier

The disc is 296 diameter and the offset from the mounting face to the inner disc face is about 14mm. I can’t be definite as the disc is warped, which is why I need a replacement.

This one's 296mm, but I'm not sure what the offset is.

Anyhow I've got one fitted to my CB750F1 and it stops in the rain unlike the OE Honda one...


Edit.
I've just measured the offset on the old OE Honda disc I removed and it's also 14mm, so the EBC MD1062LS should fit OK.

F Models have a 5 bolt hub the earlier models were 6. Hopefully the offset is the same across all front discs

Steve,

well noticed, the fitting list on that EBC link I provided earlier must be incorrect.

"F Models have a 5 bolt hub the earlier models were 6. Hopefully the offset is the same across all front discs"

Sorry and I hope I've not misled anyone...
