What is this hole for?
« on: September 16, 2015, 05:30:27 AM »
77 cb750k. Does anyone know what this hole is for? Same on both sides of bike looks to be the same size as the shock mount holes. Seems to me you could attach the shocks there and lower the seat height. Anyone know?

Interesting. That's not stock. Looks like a modified swingarm to lower the bike.

Yeah, I didn't think it was stock but cant see any difference other than the extra mounting points.

Permanent lowering block. I have removable ones that I took off mine.

I've never seen anything like that. Seems a lot easier than putting a 16" rim on!
