Thumbs up The Suspension Thread!!!

I'm going to take the time to start a thread with as much information about Hyperstrada suspension as possible. With as much focus on upgrades as I can find. If anyone has reviews or more info to share on stuff place post it up or let me know and I'll do my best to get it added to this thread if it survives.

Forks
The right fork leg is where all the "magic" happens. The left fork leg is pretty much a decoration, meaning it it totally empty. As we all know they are static, meaning not adjustable. The stock forks are 43mm upsides down units with 150mm of travel (Hypermotard 170mm/Hyper SP 50mm USD with 185mm of travel). Bellow are your options for upgrade.

Fork Upgrades
First would be changing oil weight and air gap.

Second is going further with new springs and new valving.
Race-tech -Race Tech Suspension -
-Zippy49's thread on Race-Tech upgrades- Fork upgrade for Hyperstrada

Third would be getting cartridges. Currently avalible cartridge kits are:
Andreani - Fast Bike Industries :: Ohlins #1 Service Center - Dave
-NurseDaddy's install of Andreani fork carts- The Andreani Install: How it went.
-NurseDaddy's review- Andreani Fork Upgrade: The Review
Traxxion Dynamics - Motorcycle Suspension by Traxxion Dynamics - Dan
Mupo http://www.motoracingshop.com/produc...05&language=en (Thanks Veggisville)

Lastly swapping out the whole works!!

Rear Shock
I find the rear shock to be fairly decent for an OEM unit. The shock is made by Sachs. On the Strada the shock has a hydraulic preload adjuster near the frame on the left side and a rebound adjuster at the bottom on the shock near the swing arm. Rebound is adjusted with a flat head screwdriver or the like. There is a remote fluid reservoir as well. The Hypermotard does not have remote preload adjuster or reservoir. The Hypermotard SP appears the have the shock mounted upside down with a piggyback reservoir and 175mm of travel. It is adjustable manually for preload (as is the standard Hyper) compression and rebound. This is an Ohlins unit.

The stock shock adjustment is
Preload 17 clicks
Rebound -- turns

According to the parts fiche the 2014 "low" model has a different part number then the "standard" Strada. The "standard" shock seems to be the original one as I don't see any changes. What the specific difference is between both shocks I don't know yet.

36521241A Standard height Strada (150mm travel)
36521251A Low height Strada

Rear Shock Upgrades
Revalve and spring:
Race-tech - Race Tech Suspension -

Swap from another bike

Aftermarket . Aftermarket suppliers are as follows so far as I know:
Ohlins Fast Bike Industries :: Ohlins #1 Service Center - Dave
Wilbers - Beemershop Home Page - Ted
Mupo
Matris (rumored)

Lastly if anyone has anything to add please let me know. As the time goes on more and more parts will come out and more people will have reviews of stuff to share!!!

Thanks for the list.

Just one thought her: I don't think one fork is doing nothing: one is dealing with compression and the other rebound. At least that's typical with this design.

It's sad but true. The reviews I have linked to prove it. I'm hoping to have both ends done thus winter so I will post up then. I'm glad people are seeing this thread, I hoped we could pool our knowledge and experiences together and make the ultra thread!!!

then how come zippy showed us two sets of spring systems when he gutted his forks? he said damping is on the RH side, so perhaps compression is on the LH side. not exactly empty

Stock forks: One fork has a full-length cartridge with a fork spring on it, secured by a bolt at the bottom inside the axle clamp. The other fork has no cartridge but a small piston of some sort, all of ~8" in length that looked like it didn't do all that much. As such, there is no bolt hole in the bottom inside the left axle clamp. Memory fails me as to whether there was even a spring in the left fork. Not sure if there was. I'll look in the garage to see if it's with the parts I took out.
UPDATE: there's a spring inside both legs, only damping in one leg.

The Andreani install puts two cartridges in, with rebound in the left and compression in the right, and preload on both.

Was there a spring in the other fork leg?

Here's a fact: There are absolutely ZERO damping related parts in that LH fork assembly. It is exactly as I posted, and I saw those innards with my own eyes. There's a compression (main) spring, the rebound ("top out") spring and preload assembly, and a plastic spacer. The RH has a two-way damping assembly, the small round thing to the right of center in my pic. That's the "Gold Valve," and it's a Z1000 piece modified to fit this installation. The mounting stud is a different thread and diameter, took some machine work. Each pic is of the container with each fork's internals, please look again.

I will ask RT if they can revalve the rear shock. They can certainly change the spring, although I don't need that. The tech who did my forks said that the shock was not rebuildable, but he might have been talking about the HYM unit. I can ride down there next week to show them mine and ask. But I agree that it's not that bad - not nearly as awful as the forks were.

And thanks for the summary, Strider. Not sure why you are booing it, though...
