Rear Shocks

[vamootsman]

Who has installed, and can give feedback on aftermarket shocks? Not lowering shocks, replacement shocks (that are supposed to improve ride and handling). Do they have pre-adjust? compression adjust? rebound adjust? Do the adjustment actually have an effect?

[Reaper]

I bought a Ohlins kit in Thailand, compression and spring preload adjustable, the price was 16500 baht = around $500 for two Ohlins shocks, $250 per one Very good price for Ohlins, the no.1 shocks in the world .
Firstly I wanted to buy YSS G-euro shocks, they are much cheaper, around $150, and they are best bang for the buck no quastion about it imho. YSS also offer pcx shocks for $50-70 and they say they are great!
I did a test ride on those YSS G-Euro shocks, and I felt that rear wheel sticks to the ground much better, the ride seemed for me much controllable and sporty, specially in the corners. But they felt a bit
harsh for cruising. Most people buy rear shocks because they ride with the passenger, and OE shocks are weak for this, the OE rears sags too much. If you ride alone, you can stick to OE shocks.
If you want more from your bike - there are many shocks on the market to go with. I decided to go with the best. Still didn't try Ohlins, now I repair my damaged engine
All the adjustments have the effect, I am sure, you have to get a proper spring rate on your shocks first.

I meant to say "pre-load" adjust.

I fitted the YSS G Euro shocks, and found the ride better than the standard shocks. It's a slightly harsher ride over bumps, but the bike definitely sticks to the road better. I'm much more confident cornering on these, just wish I could buy Michelin City Grips to complete the handling package.

Then again, it might be all inside my head

I know that you are more interested in the regular shocks instead of the lowering shocks, but oth of our bikes have the Takegawa lowering shocks and they provide much better ride comfort than the oem shocks do. They don't have all of the adjustments that the YSS or Ohlins do, but they do have some adjustability. With them set at their middle setting the ride is very comfortable, even though we do not ride 2 up. The point is that any adjustable shock set will do better than the oem shocks, so you don't have to spent $500 to get ride comfort on these scooters.

I ride loaded with a Top box and sometimes carry a passenger.

[vamootsman]

So I need adjustable preload and compression damping at minimum, would prefer to have rebound damping too.

[Reaper]

If you want all-adjustable shocks, they will be pricey and special order, if you do racing on your bike! All the models on the market today are not all-adjustable. Most of them got only the spring preload adjustment, Ohlins comes with the compression adjustment. PCX is not a racing bike, simply no need to mess with these things. I advice you to try YSS G-euro series shocks, it comes with different spring rates: L 70kgs, XL 70-90kgs, XXL 90-110 kgs. Powerbypcx, kdprojectracing, etc they all sell them and do ship overseas.

[vamootsman]

I have been looking at the YSS G-euro, it's probably what I will go with. I'm used to being able to fine tune suspension on my race bikes, but their mountain bikes. My old Honda Night Hawk S had Preload and Compression adjustment which was great for adjusting between one up and two up riding. When their are 2 of us on the PCX we come in at about 300lbs, So about 136kgs. Me alone, is 81kkgs With full clothing and gear. You think the XL will be the best of both worlds? Afraid that XXL will be to stiff for me solo.

[Reaper]

I am 105kgs and xxl felt stiff to me, i didnt try XL so can not advice. There is another yss g-euro plus shock, it is "upside down", the tank is on the upper side of the shock. But these g-euro plus are coming with just one spring rate, not sure but i suppose between L and XL. For me g-euro plus are better shocks.

[vamootsman]

The info I can find doesn't say anything about the Plus version, and on The PowerbyPcx site the review says it only has Spring Preload. I'm actually little afraid to order as I have no idea if I'll be getting what I want.

[Reaper]

Actually all the YSS shock kits for pcx come just with the spring preload adjustment. But, YSS do a huge range of shocks, they even are in superbike championship series, so they can offer you any shock you want to, just contact your local YSS dealer.

Talked to Klaus at YSS USA today. He is looking into it for me. Thanks Reaper

[BenChiew]

The reported improvements are at higher speeds?

Talked to Klaus again today. He says the G Euro is new old stock being sold and that it has been replaced. In the US the replacement with piggy back res. is around $450 a pair. Non res. model is about $360.

He thinks he can put a pair together with a res. and compression damping control with proper spring rate for between $600-$700. Supposed to confirm that later this week or next.

Rode 2 up and the ride quality difference on the stock shocks is a ton better. Am now convince that adjustable spring rate ant minimum would be a huge bonus. How much to spend is another matter.

[vamootsman]

Broke down and ordered a set of YSS G-Euros on Bikerbitz. If they don't live up to the expectations will have to have Klaus build me a pair. May have him do it anyway, just so I can get exactly what I want.

I have just received my YSS G-Euros from Bikerbitz. I decided to order a pair because of the weight I am packing and I understand it should improve the ride. Not sure if I really needed them, but my trip was so cheap I decided to treat myself. I hope to get them installed this weekend and give you all an update on my feelings about them.

What are both of you doing to the front end to avoid a mismatch?

Never understood fiddling with the rear suspension. It's the front end that that does all the work and is the most easily improved. Fork oil and 2ps

[GeorgeSK]

IDK - it is when my rear wheel hits that I most get my teeth rattled (especially with the Admiral on the back). I have better success with evasive maneuvers with the front wheel,but the back will often hit when the front is a miss. I expect for control the front does more of the work, but for ride comfort, I too would probably start with the rears.

From the prices mentioned in this thread, however, it does seem an expensive experiment.

The rear gives much more jarring hits on my bike than the fork, so starting there. I haven't seen any negative comments from on performance of aftermarket shocks, other than from members who haven't tried them telling others they're a waste. I'll spend my money and If I'm wrong, I'll just have cool looking rear end.

As far as the fork, changing the oil visc. could improve things if possible, but everything I've read on this forum says the the forks are non adjustable, so not sure what you mean by 2ps. psi? If so, how do you do that on a fork with no air valve?
