Title: YSS or Hagon rear shocks
Post by: DTTW on Sunday, 09 June 2024, 06:47 PM
Found out that the right rear shock had seized and it soon started to leak on my K5 (60k). Tried to fix the thing with instructions found here, but with no luck. First it seemed to hold, but soon started to leak during a track day. :facepalm:

Read the forum and decided that instead of sending the shocks for an overhaul, maybe a pair of new shocks might be the better choice.

I'm tempted to go for the YSS YSS (https://www.wrs.it/en/shock-absorbers/149091-shock-absorbers-couple-yss-suzuki-gsx-1400-02-07-8858803460512.html) due to better quality (?) but also as they are adjustable.

Any arguments to go for the cheaper Hagons Hagon (https://www.wrs.it/en/shock-absorbers/78774-hagon-rear-shock-absorbers-suzuki-1400-gsx1400-js1bn-2001-2010.html) other than the price? I do mostly solo riding with some luggage and track days maybe once a year. I weigh around 80 kilos if that makes any difference.

Ikon would be my choice. Koni. Made in Australia. Even with freight to north very cost affective. Just another choice. https://www.ikonsuspension.com/product/7610-1636/ They are good to talk to, rebuildable,i dont need replacements, my stockers been rebuilt. Just an option over stupid other brand prices.

@DTTW Depends which YSS Shocks you are looking at, as they do a range compared to the Nitro's. Both are good shocks for sure, and the Nitro is a tried and tested shock with many owners, however, the YSS G-Series gets excellent reviews and look much more "standard" as well. Mind you, a few more pennies to purchase.

At the end of the day I think it comes down to how deep your pockets are, there's really not much between Hagon and YSS IMO. I suppose with Hagon you can custom order them for length and your weight so they are suited to you personally.

Before you do anything though, have a word with the guys at FTR - these are suspension specialists and their service is bar none - they cover a range of shocks including Öhlins, K-tech, WP, Showa, KYB, Nitron, TracTive and Andreani.

Cheers gents. I've contacted both Ikon and FTR. Good comment re the freight costs Grog. Also fast delivery would be bonus, as I'm heading for a trip on 24th. If it proves to be too tight schedule, I'll probably gonna give the shock some.. err shock treatment to make it hold for some 2000k's.

Dave, nice to see you still active here. :hat: It seems I've created a habit to be more or less active here only during the "driving season", so thru May to September.

I see that I manage to hid some links in my original post. The YSS that I was considering are either RZ362-335TRL-07-88 or the RG362-335TRCL-07. Hagons model is 33048TTSA.

I'm not looking for high performance shocks, but rather good quality and reliability. Probably the G series are bit too expensive, given that they do got the looks though.

I do like the all chrome look it's a little old school.
If I ever replace my original ones (serviced regularly) I'd go with those.

I have been looking at Hagon's but those shiny one's look more like the higher end of their range being SN stainless steel.
Title: Re: YSS or Hagon rear shocks
Post by: DTTW on Thursday, 13 June 2024, 06:52 PM
As to update this I got a quotations from both FTR and Ikon. FTF offered YSS in my price range, 500£ for the Z series, I believe, they didn't mention the model, and 700£ for the G's. Ikon's really are a cheap option, even delivered to Finland, AUD$740, or 455€.

To further make things more complicated I called today to a workshop, specialized in shocks. They quoted 300-400€ for an overhaul. I'm starting to feel that overhauling the OEM ones is an option after all. I do like the look's of the OEM shocks (imma sucker for piggybags), and the price is not that bad. They said they can get the overhaul kit's for these KYB shocks. My only concern is that whether they'll perform good, or if they gonna fail after few years. I'm driving K5 so the rear shocks were of better design vs. what found in the earlier years?

So, probably gonna give the OEM's a chance after all. Unless the YSS RG362 are worth the money, around 700-800€? Compared to OEM'S. :whatever:

I can't fault the originals when working, so my preference would be to stick with those. I've not tried the other makes to compare, but I've never felt the originals needed improvement.

It's interesting somewhere can still rebuild them, the places that used to in the UK have stopped. They say they can't source a particular O-ring for the internals, I assume it's a strange size or profile.

DTTW, i had mine rebuilt, never a problem before or after really. I dont mess with forks or shocks even though im a mechanic, i just pay the suspension shop, works for me.Just not interested in those jobs. I know my choice, rebuild stockers. IMO only.

I only bought the Hagon's to lower the bike for my short legs - 29inch inside leg - getting too old and stiff to refit the originals so they will stay in a box in MY GARAGE until I give up the 14

I paid 525€ for the "RG362-335TRCL-07" in 2021. Found one offer today for £559.96 (ebay UK (https://www.ebay.co.uk/itm/185662747098)

It pays to search.

I had the originals (K2) rebuild - including repair of preload adjuster for 450€ (2017?). The top o-ring for the preload adjuster was not replaced - presumably not able to source them. Same work today 520+€. They failed in 2020. Hadn't played with preload till then, so may have failed way before then. Nitrogen was also gone.

Was an easy decision for the RG362 as I can service and rebuild them now myself. Tech-support (Center in the Netherlands) is great. Parts readily available from different sources.

K5 shocks preload adjusters are much better in respect to preload adjuster fail (as per guy on german forum who repaired many of all years).

If only I could find pair of RG's for around that 700€, that's probably something I could live with.

Andre, eBay must know I'm in a desperate position since they are asking £671.95 through that link. Or is it an affiliate link from which you get your cut from?  :lol:

Also I found out today from my father-in-law that we might have a local guy here where I live, who could also repair these. This town is quite small, so I would be happily surprised if that would be the case. Anyway I'm checking with him tomorrow if his up for the task.
Title: Re: YSS or Hagon rear shocks
Post by: Andre on Friday, 14 June 2024, 05:01 AM
No idea why it shows you another price. Was also only intended to show that a bit of (re)search and some patience may save some £$€. As you live in Finnland, total costs depend on where you order from. Maybe my screenshot shows no VAT as customs would add German VAT and customs.  ???  duties

Gotcha. Don't know either why the price is showing differently... Back in the days I managed to get a good price for the full Akra, with some patience and good luck.

I fiddled with the settings in ebay and managed to find pair of RG's just under 700€. That's more like it, but I think I can't quite justify the difference between repair and new shocks. As said, I'll be wiser tomorrow re the capabilities of the local workshop.

Andre, when you said you can rebuild the RG's, do you also fill the nitrogen by yourself?

I wonder how I always end up down the rabbit hole. I've been calling quite many places, and got some good information meanwhile in regards the rear shocks.

There were few who said nothing can't be done to the shocks, few were doubting nothing could be done, but after a googling they said it's probably possible to do, where as one quoted me the job as we spoke.

So, it seems they can be rebuilt afterall. One mech said he'll make them serviceable, not sure what he meant. Probably has something to do with the piggybag. I think the best advice was from this nice bloke who said I should try and do quick and dirty fix first: take the spring away, test whether the shock itself functions ok, if it is, change the o-ring in the preload chamber. He even gave me the contact info for the retailer who could probably find me the correct o-ring, I just need to know the size first. He said if I encounter any issues during the maintenance, just give him a call and he'll help me out. Geez, there is some humanity left in this world after all.

So, tha's the plan ATM. After the trip around Finland I'm gonna take the shocks apart, check the functionalty of the same, and try to change the o-ring. See what happens and take it from there. If no luck then going to send them to a specialist for a rebuild, was quoted 80€ per shock + service parts, not too shabby.

Anyone has any info what's the size of the said precham. o-ring might be? :whistling: Cheers

From a doc someone made.

These "o-rings" are L-shaped!

The earlier version (II) of shocks has white rings, the last version (III) of shocks has black ones. The dimensions differ!

(II) upper part 46x2.0, lower part 45x2.5 mm
(III) upper part 50x2mm, lower part 45x2mm

I'll keep this post updated.  :clapping:

That explains why they are so hard to get hold of! I never knew they were that shape.

Should show a bit of the shape (version II). As well as the crud (which destroys the ring and then some) that collects because of inadequate design.

Somewhere on here or old org. Someone made threaded adjusters to replace the hydraulic one. All dimensions etc were posted. Ive searched but cant find it. VICI maybe it was??

Would like to know more about this, what needs to be done, what parts are required to resources etc. The stock preload seems bit of a gimmicky to me.

Except for mono-shocks, where it might be difficult to reach, imo the hydraulic adjusters are all gimmicky. :stir:

I'd start by taking the gimmick off and taking measurements. All the needed parts might be available online. Otherwise find someone with a lathe who is willing to do the threaded part.

UK based but these may be worth a try for the seals & O Rings, I used to use them when working in the Hydraulic industry, strip a Hydraulic Cylinder/motor pop all the seals in the post to them and a week or so later a full set of seals would arrive for very little money
