Swing Arm K2 vs K6 - Is K6 swing arm really stronger?
« on: June 28, 2013, 01:15:49 AM »
.... have searched but could not find a comparison where the differences are visible.
I have read on the CB750 timeline that 1976 got a stronger swing arm.

- Is K2 Swing arm really weaker than std K6-1976 swing arm?


My original swing arm has no brackets for chain cover and is degraded in general with need of new paint etc. I have found a restored swing arm, powder coated with new bearings, but it is a K2 swing arm.
(I have a "Dresda" but it is too narrow 220mm instead of 240mm where the wheel should be fitted, otherwise OK. Back to OEM then)
