Changing rear shock DIY

Saw this video and I think it looks easy enough to do.

My ordered YSS GZA rear shock will arrive tomorrow and I have nothing much better to do over this weekend.

I'm not sure if I'm right, but it looks so simple.

1. Remove the underseat box
2. Remove the air filter box
3. Remove some of the exhaust screws to get more space

What size wrenches should I be needing? I see 12, 8?

I also have a torque wrench and the torque values from the service manual.

In reality, this will only cost me a few bucks if I visit any garage here in Thailand, but there is something satisfying about manual labor and fixing or messing things up with your own hands.

I will have the front shock upgrade next week done by a mechanic. I think that one is a little bit complicated for me so...

I'll let you know if I mess it up or something

It looks like it is much easier (in some ways) on the newer bikes than on ones like my 2013 model. You still have to take the underseat storage bin out, but on the 2013 model you have a bit of plastic to remove. I certainly didn't have to take as many screws and bolts off, but that guy has figured out how to do it without taking very many plastics off. Keep in mind that he has been doing this for awhile, so it looks easier than it is.

[alx123]

I agree that it looks easier than it's actually is.

I just realized that in the 2016 model I don't even need to touch the exhaust and the air filter box since the lower rear shock's bolts are already unobstructed.

My shocks arrived today so I will try to install them tomorrow...

So I did it today and it's not as difficult as I thought it will be.

It took me approximately 1 1/2 hour as I decided to proceed slowly and carefully.

Here are the steps, jusyt like in the video above.

1.Remove the Givi Box, the plate, and its bracket.

2. Remove the rear cover using a screw driver

3. remove the handrails bolts using 12mm wrench

4. Remove all the bolts and screw holding the storage box (10mm bolts)

5. In my case I didn't even remove the storage box entirely, just lift it a little bit and then you will have enough space to remove the nuts on the top of the shocks.

6. Remove nuts (14mm) on top of both shocks, as well as the bolts (12mm) holding the suspensions below. (no need to remove air filter box in 2014-2017 model)

7. Install both the new YSS shocks. Should be easy.

8. You need to remove the bolts (14mm) holding the muffler as it's not possible to re-insert the rear shock bottom bolt of the YSS shock. No trouble reinstalling on the left side though.

9. Once all bolts and nuts of the shocks are tightened, you can now slowly reassemble the scoot in the reverse order.
Tighten muffler > reinstall storage box > handrails > back cover > givi bracket and plate > givi box

Notes:

Rear shock top nuts torque (25 NM)
Rear shock bottom bolts (16NM)
Muffler bolts torque (30NM)

Done! and I'm glad I didn't mess up

[GeorgeSK]

Nice clean write up - thanks. I'll be very interested in your evaluation after a few rides.

[Mel46]

There have been a few inquiries on this forum about those types of YSS shocks with the canisters. It seems that they have become hard to find. I am glad that you have located some. As I understand it those are really comfortable. Let us know how you like them.

[alx123]

Initial impression seem to be that this shock is stiffer than the OEM. I can feel all the road imperfections, which I'm not sure if I really prefer. On the other hand, I feel like the tires are gripping much better,esp on curves.

Riding alone, and as a light guy at 65kgs (144lbs), I like the OEM better because it is smoother. Riding with a back rider though, this shock works perfectly.

I'm gonna give it more time and give my feedback here again. But I guess, for non-Asians who are weighing more than me, this shock should be perfect. I adjusted the shock to its minimum preload setting but still it feels like a little stiffer.

not an option, im on my ideal weight and don't want to be sluggish on the mat

After 30 kms of riding today, I can say that I'm starting to like the new YSS shocks. It gave the scoot a different feel when riding;It feels more sturdy and with better road feedback.

My initial impression on it's stiffness is based on the fact that I can feel the road surface imperfections more now. But on bigger humps and bumps, the YSS gives a much cushioned bounce than the OEM shock. When riding with a passenger, it's perfect.

Now I'm thinking of upgrading the front forks next, as I can feel its inferior performance more now.

The YSS front fork upgrade kit is more expensive than my YSS rear shock though.

The new shocks in red really look great with your white PCX.

[Jge64]

ive had two sets yss's- one resevoir and one regular..

both sets felt much better once broken in at 50-100 miles.....

the preload settings do a lot, try messing with a few diff settings....

[Old Grinner]

The shocks look good . . ..

The pics show close-up detail of what you had to do to swap them out.

Now you can dial in the ride a little better.

I believe it added a bit of red variation to the rather boring all black and white.

Yeah, it feels that the shock feels different the more miles tat I'm using it. Or it could be my butt getting used to it too

I'm using the minimum preload for now, as I'm guessing this will give me the smoothest ride as this shock is a little stiff? But I will soon try diff settings to see how diff preload feels.

Right on, it feels like a diff ride for now. I will try to upgrade the front suspension as well and maybe this will delay my itch to upgrade to a bigger scoot maybe by a year or two.

[RobV]

I want some! Where did you get the shocks from?

[Mel46]

I am going to guess that they cost a bit over $250. I know the ones with the canisters are not cheap. Remember, alx123 lives in Thailand. I am sure they cost less there.

You could probably find them on Bikerzbits.com
