Testimonials
“ The new YSS shocks are fully adjustable in both compression and rebound and can even be revalved or repaired if required. The YSS shocks have made an enormous difference. With the original Mean Streak standard shocks, the bike would jar the back if set too hard or cause the bike to wallow on undulating roads, especially two up. They had no rebound adjustment. The new YSS shocks have made a great ride, even better. "
“ I got the RG 366 TRCL and had my dealer set them up for me. I was at least 2-3 seconds faster at the track yesterday than I had been before and my ground clearance was MUCH better. I would scrape foot and pegs before and have a hard time getting my knee down smoothly through the turns. I went 10mm higher on my ride height and that combined with stiffer springs gave me a much better angle/position on the bike. Another nice thing is that they look so much better than the Ohlins wannabe's that are OEM. Plus the silver/red of the YSS matches the red. "
“ Do a search here for YSS shocks - they are brilliant - a very good product without the $$$ of ohlins. "
“ The Ikon shock for the GT is a gas shock with pre-load and 4 position rebound damping adjustment and more expensive than the YSS Z-302 TRL Twin shock, which is a gas shock with pre-load and 80 click rebound damping and costing less. The less expensive YSS gas shock has much finer control of the damping adjustment. "

Philosophy
“ It's unwise paying too much, but worse paying too little. By paying too much, you lose a little money. By paying too little, you could lose everything, because what you've bought would be incapable of doing what it was bought for. The law of business balance prohibits paying a little and getting a lot. If you deal with the lowest bidder, it's wise to add a bit for the risk you run and if you do that, you can pay for something better. "
That said and with this in mind, the Suspension Shop is servicing the motorcycle community in Australia and overseas as well as furthering the research, manufacture and development of top quality world class shock absorbers for racing purposes and casual driving without breaking the bank.
“ Installed YSS fork valves and progressive springs last week and tried them out on a ride yesterday (Saturday). Unbelievable difference. Gone is the bottoming out on sharp bumps and they instill confidence on turn in as dive is reduced. Cost was $630.00 supplied and installed. "

“ Just thought I'd let you know Walter the new YSS's on the 490 were great on those rough NSW cow tracks, could even actually walk after Lakes meeting. "
Legend, Newcastle NSW
“ Woooo Hooo. :-) :-) They arrived today. They fitted perfectly with NO mucking around, look fantastic. Overall finish is very pleasing and nicely put together. Feel great when bounching on the bike. Damn, I got this thing rego'd. :-) "

Technical Support Guide for Adjusting, Fitting and Removing Your Motorcycle Shock Absorbers in Your Workshop
Adjustment of Your Shock Absorber

YSS Shock Absorber Adjustment Sketch
On your new shock are a wide range of adjustment possibilities that affect the shock in various ways. Now we will explain to you the ins and outs and above all, how it affects the handling of your motorcycle. Prior to delivery, the shock was adjusted to your personal requirements (that's why we needed information from you - for your shock.) The questions asked about your body weight were not based on curiosity, but to determine the load carrying capacity. For determining the spring rate, we asked about the targeted application of your bike (i.e. Touring with or without luggage or pillion, racing or just everyday use).
We then manufactured an individual shock for you, from the information you provided us. We now ask you to note these basic adjustments we have given you, so that you can then fine-tune the shock yourself. You can however, adjust the spring rate with the C-spanner or with the optional hydraulic spring pre-load tensioner. As with most YSS shocks, a hydraulic spring tensioner can be fitted, to make spring tension adjustment child's play.
Default YSS Shock Adjustments
| Your YSS shock has the following basic adjustments | |
|---|---|
| Basic Adjustment | Clicks |
| Rebound | 60 clicks |
| Compression low-speed | 20 clicks |
| Compression high-speed | 20 clicks |
| The spring rate has been YSS pre-adjusted | |
Rebound dampening
A red adjustment wheel at the base of the shock is there to adjust the suspension and rebound rate. The rebound dampening is adjusted through 60 clicks (You can feel and hear them). The maximum rebound dampening is reached by turning the wheel to the right. So, if you turn the wheel to the left, you are slowing the rebound.
Compression dampening operates in a similar way. The compression adjustment is there to adjust the spring speed.
The Compression Phase Absorption
| The compression phase absorption is divided into two ranges | |
|---|---|
| Compression Phase Absorption Range | Adjuster |
| 1. Compression phase low-speed | Titanium Adjuster |
| 2. Compression phase high-speed | Black Adjuster |
| Both are found on the reservoir. Use a good fitting screw driver to adjust. | |
The Compression Phase Function
| The compression phase functions as follows | |
|---|---|
| Compression Phase Function | Spring Speed |
| In low-speed | up to 0.5m/sec spring speed |
| In high-speed | from 0.5 to 4.5m/sec spring speed |
| This partitioning into these two ranges increases and extends the function of ride travel and safety. | |
Tips When Making Changes
| In order to make changes, first note the basic adjustment to give you a basis to work and test from. Under these conditions you should complete your test run. |

Examine Spring Stress and Native Spring Travel
| Please examine the initial stress in the spring and the native spring travel according to the SKETCH on top of this page. |
|---|
| A = total spring travel-rear wheel of the ground: A = 100% negative spring travel or static sag, motorcycle weight without rider or luggage with correct spring rate: |
| B = A minus loaded sag motorcycle weight plus rider and luggage with correct spring rate: |
| C = A minus 1/3 from max, spring travel measurement from loaded sag = Suspension Travel. |
The Rule of Thumb
| Rule of Thumb for Static Sag | |
|---|---|
| Riding Style | Static Sag |
| Road | Front 20 - 30mm, Rear 5 - 10mm |
| Road Racing | Front 15 - 28mm, Rear 3 - 10mm |
| Off Road | Front 28 - 35mm, Rear 15 - 30mm |
| These values are reference points and they can vary up or down. | |
Fitting Your Shock Absorber
Adjusting | Removing | Suspension Set-Up | Technical Terms | Frequently Asked Questions | How To Choose The Right Shock
All work on a motorcycle should be carefully thought about and the work to be planned prior to starting. For a start you should obtain the necessary tools and have a good workspace.
The removal of the old shock and the fitting of the new shocks are feasible for everyone without special technical knowledge or talents. There are no special tools required.
Another point of importance to be taken into account is interference: Check that the belt and chain drive are tensioned correctly and that the swing arm can move freely through its entire arc. Check the operation and clearance of brake lines, cables and/or shaft.
Removal of The Original Shock Absorber
Fitting | Removing | Suspension Set-Up | Technical Terms | Frequently Asked Questions | How To Choose The Right Shock
In most cases it is necessary to remove the seat and tailpiece. Position the motorcycle on a workshop stand or on the center stand so that the back wheel is off the ground. Removal of the rear wheel is not necessary in most cases.
Loosen the bolts on the top and the bottom of the shock and remove it. If the shock absorber works on a lever system then it may be necessary to loosen or remove the lever system in order to remove the shock.
After the removal of the old shock, compare it to the new one (maybe the new one has a remote reservoir or a hydraulic spring tensioner). If it does not look like the old one, do not despair. You may have to find mounting points for the remote reservoir or hydraulic spring tensioner. Places may generally be found on the sub frame. You may also have to turn or rotate the new shock into its new position making sure to be careful. Once the new shock is in place make sure it does not touch any part of the bike that it shouldn't. Re-tension all the bolts to the manufacturers recommended settings.
When fitting the remote reservoir or hydraulic spring tensioner either in the original place or new one, use the new clips and rubber mounts. If a new position is to be used try to make sure it is not on the same side as the chain. Also, make sure that the hose is not stressed and does not rub on anything (i.e. Tyre). Ensure that the remote reservoir or hydraulic spring tensioner do not interfere with the movement of the suspension on full travel.
Last but not least, make sure you check all the nuts and bolts. And please, do not make any adjustments to the shock before a test ride. See: Adjusting your Shock Absorber.
We hope you have a problem free shock absorber installation and with it a completely new and better riding experience.
