interesting. do we know if these fit the RC?

 

[RoninJames]

i mean i see they have a 300mm length shock which is what our stock is. and you can get a 10mm height adjustable version.... will the bolt eyes fit as is or need spacers/shimms?

 

[psych0hans]

I think they give you the attachments as per your ur need, so if you specify what you require that's what they will give you. They have mentioned that the eyelets and spring rates can be customised.

yea i actually researched their site a bit more and when you order you can give them eyelet sizes etc. i am going to put a call in this week and get some more info.
$500 is a great price

 

[psych0hans]

I sent them a mail today, let's see what they say...

 

[RoninJames]

i read a couple reviews online and they have very positive feedback

Bumping this thread.

Figured out I can't run the R6 shock with the lowering link on my bike. Now looking for affordable shock upgrade.

Anyone running the YSS MZ506 300TR 38?

Looks like £290 shipped worldwide.

I spoke with YSS in Thailand and YSS here in the US and the YSS MZ506 300TR 38 has been discontinued. You can still buy the YSS MZ456 300TR 38 and I have about 300 miles on mine. It's 1.5 lbs lighter than stock and I was able to order mine for $375 USD with a black 120Nm spring from the guys below. The shock normally comes with a 100Nm spring which would be good for light riders but I weigh 200lbs wearing all my winter gear so I'm trying a 120Nm spring. Based on travel & sag measurements, I may swap to a 110Nm spring but it's still better than the OEM unit with the stiffer spring.

PS. I told them to change the description on FireFox's Ebay listing but it looks like they're still advertising spec.s for the MZ506 (50mm piston) shock instead of the MZ456 (45mm piston) that they're actually selling.

ah, thanks Brett, didn't realize this was the one you were working with... Impossible to search the forums with YSS as it has too few characters.

Yes, I think this vendor is the best price I've found and I'll purchase it direct off eBay.

Can you confirm spring dimensions? I'll look for other local spring options as well, probably trying out the stock one to start. On off chance you have shock off bike, I'd appreciate a photos of the top mount of the shock to gauge whether I will have issues with my lowering link...

I know what you mean about searching for YSS on the forum Andrew- I had the same problem!

I'll be heading out for another ride in 4 hours if the weather cooperates but I'll take some pictures of it in a couple minutes and will email them to you. Reply to my email with any measurement questions and I'll take care of you ; )

Found what I think is a good price on the MZ506-300TR-38, 281 Euro shipped from Italy.

Hopefully I don't get hammered by customs.

Not sure why the 50mm was discontinued, probably overkill for these bikes. Presumably heavier too actually. Price was right though so I jumped on it. I'll have heat concerns with proximity to pipe so hoping larger 50mm bore is increased oil volume to ostensibly better handle the heat.

Just found this thread. Has anyone used a YSS shock on a 17+ track bike? If so, what are your impressions?

 

[KodakMoment]

Being that there have been good things mentioned about YSS, I think more importantly, if anyone has used this shock over time, how has it stood up?

Edit: just so everyone is aware, these are emulsion shocks we're discussing. So, it's not always a fair comparison to a non-emulsion, more expensive shock.

Because it is an emulsion type, for my uses (racing and track days), I'm not interested. But I thought I'd help move the thread along with these points

 

[CDN Duke]

I've been happy with mine since I installed it in 2017. Several track days and a few thousand kms, trouble free. Very happy with the performance to date.

 

[John390]

so, how does the cost factor out? IE 281 Euros, convert to Canadian, plus shipping from Italy, duty if applicable, tax if applicable?

Once all this is factored in, how close to a JRi or something similar?

It was 281 Euro shipped. I think I only paid 13% HST on the ~252 Euro price before shipping. I am pretty sure I was under C$500 when all was said and done.

 

[John390]

ok, so still cheaper than the next step up.

I am happy with my rear setup, but its good to know one doesn't need to spend $800 or more to get it done.

John -- If we're comparing the functionality of this shock to other emulsion types, then it will be similar in functionality only. But in terms of quality, then it will not be similar.

Also, emulsion shocks are not ideal for track or racing; they heat up quickly and lose their performance. And given the location on this bike with it being so close to the exhaust, that's a concern.

This is not a comparable shock to JRi, Penske, Ohlins, etc. It's an alternative, given the price, but the quality (and adjustability) of the aforementioned brands is much better. I'm sure this shock is much better than the stock shock. But, IMHO just buy the best and buy it once.

 

[John390]

ahh, ok. I'll have to look up the difference in an emulsion type vs non-emulsion? I have never heard of this terminology before.
