Does anybody know why in the Ohlins setup Dynamic Sag is 72mm and the standard is 54mm in the owners manual, is this predominately for off Road and do you think splitting the difference would be more advisable,

Losing 40% of your travel just sitting on the bike is very wrong in my opinion. Ohlins always specs and sells far too soft springs in almost every application I have ever seen. Personally I think they are trying to justify their too soft springs by suggesting excessively large sag numbers.
A little more or less than 54mm will be fine, but 30% of suspension travel should be your objective. I would not split the difference.

Was this an "off the shelf " rear shock or was this set up specifically for you ? I have full Ohlins custom for me and how I ride, I dont see anything like this...... The only time I have "excessive" sag is when I have an extra 100Lbs of gear in the bags...... Over the years I have a "set up" for this and I turn in some preload on the spring and maybe add a click or two of compression and rebound. It takes me about 30 seconds to "fix" the rear end / sag / ride quality.........

If your Ohlins was not set up for you and your 'needs'............ They certainly CAN do this, maybe it just needs to be set up properly by them, for you........

Hi all

The recommendations came with the manual sent which accompanies the Shock, have had the spring upgraded from 130nm to 150nm meaning the Dynamic Sag is now 60mm with 8 full turns to fully loaded, spoke to a specialist and he said a 160nm spring would be to harsh without luggage, this shock will probably need full preload with luggage, if you look at the manual which is on line for the Tenere 1200 Ohlins shock you can see the setup, can’t see the reasoning behind there setup

I have heard that comment that a stiffer spring will be more harsh and that is a bullshit comment IMO.
I don't know what you weigh but you should look for a spring that gets you proper sag with zero turns on the hydraulic adjuster when loaded as you would normally ride. That way you have the entire 8-10mm of preload available for when you load the bike up for travel or if you decide to carry a passenger.

I don't know what you weigh but for an example I am 220 without gear. My after market shock originally had a 160N spring and it was ok, but I had to put more installed preload than desired to get proper sag. I changed it out for a 170N, was able to reduce the installed preload and the ride was much better and less harsh. If I hadn't sold the bike I would have gone up to 180N and I know it would have been even better.

For example 220lbs with out gear, 170N spring, bike setup for solo riding with a top box, side racks but no cases installed. When I fit the side cases, fill them with gear and strap another top bag on the rear I only had to add 1.5-2 mm of preload to correct for the extra weight.

The nice thing about most aftermarket shocks is you can usually move the hydraulic preload adjuster up or down the shock body. So if you wanted to run a really heavy spring you could move the preload adjuster up the shock and reduce the preload on the spring. This way to can set almost any spring you choose to have proper sag with the adjuster set to zero preload setting. Haven't seen the Ohlins shock up close so I can't say how they come shipped, but if they have a threaded locking ring above the hydraulic unit they can be moved up/down.

I think the ohlins comes stock with a 200mm long spring. If you had an issue getting a proper rate spring 200mm(8 inch) spring you could get a 7inch spring and move the hydraulic unit down the body to compensate.

Don't be afraid of a stiffer spring, it will better than a softer one I guarantee. Too bad you were not closer, because I think I have a 160N sitting on my shelf collecting dust at the moment.

Thanks for the reply, I go about 187 llbs so really looking at a 160 nm spring I believe as 150nm spring rate maybe on the limit,
