Most motorcycle problems are caused by the nut that connects the handlebars to the saddle.

Damper Rod Bolt Empty Damper Rod Bolt

Hi there,

I want to upgrade the suspension on my wife's 125, (Sachs Roadster 125), and needs better damper rod. I was thinking to fit one from a CB 500, and upgrade the rear shocks too with some YSS.
Anyway, don't have any stock CB500 forks around the house, cause my CB has a hornet front end on it, and I can;t measure if it fits.

Any of you got a disassembled fork around to check the length, width, thread and pitch of the Damper Rod Bolt?


Thanks.

I'm getting ready to change my fork seals (1994 CB500) so have a couple of bolts to hand. Measurements as best I can make them:

Honda part no. 90116-KV3-701
(Item no. 20 on https://www.bike-parts-honda.com/pieces-honda-detail-1091-13MY5R41-CB500R-1994-F__0800-CB+500.html)
thread major diameter: 7.8mm*
thread lengh: 18.1mm
thread pitch: looks about 1.25mm*

* - Thread appears to be standard M8, I tried a nut on one.

head diameter: 13mm
head length: 5.9mm

Hope that helps.
