Default Ohlins blackline....

Anyone running the standard stx36s wish they'd sprung for the piggybacks? I'm looking to improve ride quality and cornering, but can't decide which version to get. I don't mind spending the xtra coin for the remote reservoir variety but I've heard the difference isn't that great for street riding. I'm lookin at the 14.25" and the price difference is substantial. Opinions?

Ive done a bit of forum searching now, and the consensus I've come to is that piggyback shocks are basically overkill on a Harley, and simply going with taller quality shocks is all that's needed to improve handling.

If there IS an actual real-world benefit to installing the pricier piggyback variety on a cruiser I'd certainly like to know.

Default Here you go

The purpose of a shock is to keep your wheel on the ground for traction.

The Ohlins have a compression valve with adjustable shim pack so you can change the characteristics of the compression to suit your needs. You look up your interactive dyno graph table and choose what you want to do with the shock.


Removing a compression valve & adjuster ****

Compression valve

Shim stacks for just the compression valve

Removing the rebound with the main piston

The separator piston is below the pressurizing nitrogen (on top of the piston) when up side down being serviced.

In place of the piston being on top of the main piston such as in an internal reservoir, the "Dog Bone" is integrated on the upper mounting end-eye so it holds the reservoir and the I-Beam cools the hot oil and the main body can allow the piston to travel full length so a longer stroke can be achieved. The gold ressy (off of a HD-357 / #6 ) & the black ressy shares the same separator piston and works the same on both shocks. The separator & ressy are used to eliminating misting, shock fade than shock failure which happens on emulsified (non separated) shocks. Look at the OhlinsUSA demo and wait until the end of the movie when the pressurized air is removed from the top of the ressy piston (on the bottom).

Piston before rebuild, notice the dirt & scorched oil.
This is the rebound adjuster and rebound shim pack.

To the answer to your question,

No, not true The shock can make the road disappear when properly set up or adjust it so you can feel the road ank know what your bike is doing and know when it will loose traction. If you Badbastard wish to know these answers ask someone who can answer intelligently. Whoever you are asking is the wrong person.

I am with Howard on this, you definitely get what you pay for. High end Ohlins are adjustable for any condition you want. My Dyna will never ride as smooth as my Street Glide, the other side of the coin is the SG will never handle like the Dyna. Both have Ohlins and do what they do very well.

Cant compare the piggybacks but I got the adjustable rebound. I used to race sportbikes casually on track and I can tell you no regrets with the non piggy backs. I ride my dyna hard in the canyons and in the city it absorbs the bumps very well. Is it worth to get piggy backs? I've always been a firm believer of you gotta pay to play lol, but def no regrets not getting the non piggybacks.

One thing to note on Piggyback is that the oil flow through the compression valve is greatly reduced compared to a single body separated or emulsion shock. That ends up reducing compression damping which give a better road feel. I do think that some of the single body shocks have too much compression damping giving a rough ride. Another advantage of reservoir shocks is that the travel can be longer per given length.

I've got a set of non-adjustable custom Blacklines from Howard and I was perfectly happy with them until I had him (Howard) upgrade the front to Ohlins Nix cartridges. Now the rears "need" upgraded to double adjustables. LOL!

Just waiting for the time and money.
