Rear Shock Hydraulic Pre-load Adjusters
 

I have mentioned on here a number of times that I often carry a pillion, so adjusting rear pre-load is a regular occurrence. I am now the proud owner of a ZX-10R shock to improve things on the rear end, but the pre-load adjuster is them pesky threaded rings, which makes adjusting the pre-load a right PITA.

I've been scouting around to see if anyone does a hydraulic pre-load adjuster unit that can be retro fitted to a ZX-10 shock, to make this job a lot easier when this shock goes in. Only ones I can find are things like WP / Ohlins / Maxton that can be fitted to their own shocks.

Any one of you suspension gurus know if such a thing as an after market hydraulic adjuster exists, or is this a pipe dream?

No sorry not a suspension guru. But in the near future ill hopefully be upgrading to a ZX10/ZX6 Rear shock. Just wondered how easy they were to fit and weather and alterations were needed?

They are available from most of the shock manufacturers (ohlins,wp,hyperpro,nitron etc)from around £120 up
The Ohlins ones would be the hardest to fit to an OE shock due to the locating pins and they all can only be fitted to shocks with a threaded body provided there is enough room above the spring and it is the right dia

See this thread linky. More info, search on 'ZX10 fitting'

Thanks Rob. I found out that these manufacturers do the hydraulic pre-loads already, but it seemed they only fit their own shocks. You say that they can be fitted to any shock of correct diameter?

In that case does the shock need to be rebuilt to fit the added adjuster? Looking at the ZX10 shock, the threaded part is at the top. So if the adjuster needs to slide on to the shock, the spring needs to come off. That does not sound like a DIY job. Is it something I can fit myself?

Looks like this is a pipe dream without spending lots of cash. Going with the 'Buy a decent C-Spanner' option to adjust the preload
