Yamaha, now makes

Pianos, motorcycles, ebike motors, electronics, and tunes engines for Auto manufacturers. That's certainly diversified manufacturing. 

 

Edited to add, Guitars and boat motors.

Not just boat motors but whole watercraft - WaveRunners.

I went from an off the shelf ( but correct ) tune on a RS super deluxe coil with hbo

To a push 11.6 custom tuned, gen 1 so without HBO

100% this handles everything better with a 25lbs lighter spring 

Even the rare bottom outs 

So I think it’s quality over features here

I don't doubt that, the 11.6 is one of the most expensive shocks on the market. And we're both just providing single anecdotal evidence of our own experiences, on one bike. But I'd wager you wouldn't be upset if the 11.6 had HBO and it's a wonderful feature on more affordable and non-custom tuned shocks.

I'm with you though on quality, I had a CC DB coil that was excellent w/o HBO. But again, it would've been even better with it lol, this argument goes around in circles.

The o-ring will never go past last few mm of stanchion on a Vivid air.  The full stroke is still there though.  You can verify by letting all the air out and removing the valve core.  Same thing happens on forks, but on some of them there's a line showing what max travel is.

Strange, my caliper shows 60.something mm where the o-ring is then 5.something mm on the other side of the o-ring to the stop, unweighted rear to measure. It is a 65mm stroke in the trailhead app, double checked in case maybe it was mislabeled. Coming up on service time so maybe I'll see something amiss when its apart.

It does have a slightly different compression tune than what the bike mfg would have shipped, c37 vs c34 but I don't think that's the cause.

Thanks for the info though, good to know it won't bottom at the stop.

And without opening the article, I am sure Yamaha did not buy Brose. If anything, the ebike division/segment/technology. 

Brose is a multi billion dollar company, a tier 1 supplier of the biggest automotive brands for all aspects of building a car, interior, exterior, powertrain, you name it.

Fun fact, the owner/heir/whatever is the guy who ordered the new Lancia Stratos made from a cut up Ferrari F430 and had a production run of 20 units planned until Ferrari said no to cutting up their cars.

That's the playing field of Brose. And I bet 90 % of people pronounce the name of the company wrong. Hint, it's not Bros 😉

If you've really got 5mm to the o-ring, you've got something weird going on.  There should be roughly a 1.5-2 o-ring's width between the end of the stanchion and the o-ring.  Like, the equivalent of 5% sag on the markings.IMG 6656.JPG?VersionId=Ww3ESb2M4LJ9eux

One guess is that maybe someone installed travel reducers in your shock after it was manufactured.  See the service manual page 51:  https://www.sram.com/globalassets/document-hierarchy/service-manuals/rockshox/rear-suspension/2024-vivid-service-manual.pdf  There are 2 possible travel reducer locations, the air can one is pretty obvious and easy to check and remove if needed.  It looks like you can check if the eyelet travel reducer is like 1 more step to check if it's present, but basically requires a full rebuild to remove.

My Vivid has HBO but no matter the settings,  nor how big the huck to flat that almost explode my ankles, the last 5mm is complete unobtainium. 

I wouldn't think its the HBO, but I can hit the same spot at 29% sag and 40% sag plus max to least compression set. HBO also set to max and min too.

A SDU without HBO and a X2 could use all 65mm stroke though, so the only thing I can guess is it's the HBO.

what bike is it on? Its my understanding after talking to EXT is that HBO is mostly needed on dual short link bikes like Giant and some DW/VPP designs where you get an initial falling rate, but at the end of the stroke you get a very quickly rising rate, exaggerating harsh bottom outs. Short links inherently are going to have a less flat compression curve.

Short links inherently are going to have a less flat compression curve.  

To give some credit where credit's due, since air shocks have gotten much better, it's been a while since any short link bikes had a significant regressive hump at the end of their travel; the most recent one I can think of is the Ibis Ripmo. In fact, many short link bikes get more progressive at the end for increased bottom-out resistance.

At the end of the day, my two cents about HBO is that it shouldn't be a dealbreaker. It's highly dependent on your personal preferences, bike kinematics, and bike setup. I don't think it'll ever be (or should be) something bike / suspension companies demand as a mandatory feature.

Seeing the new Propain, anyone heard about the new TQ motor? Hoping it’s the same mounting and electrical connections and can be a drop-in upgrade for the HPR50. But I’m probably dreamin’

Good point on the travel reducer, I'll give that a check. I pulled out the factory installed volume spacer but didn't look for a travel reducer.

This is the max the o-ring can hit:

20250331 152311

Hamncheez, the bike is an Ari La Sal that has the crab-link suspension. Its possible the c37 tune plus the progressive suspension is causing this but not very likely from my thinking, especially if adding more compression doesn't impact how much travel is used. 

If I can't see anything glaringly obvious when I service it then I'll check with RS, especially since others don't appear to be experiencing this. 

Thanks!

Some shocks may not go all the way to the end. Have you measured how far from the dust wiper to the o-ring is?

Measured the o-ring at around 60mm travel with a little over 5mm left at the end. This shock was for a SB160, but aside from the unneeded hardware and slightly different compression tune nothing else seemed unique. Sold as 230x65, unless a travel reducer was installed without mention - which is possible

And with that, last post on this until I pull it apart. 

Apologies for the hijack.

They have a ~5mm tall rubber bumper which will be very hard to compress the whole way, especially by hand

Likely.

 

(Properly) changing a Vivid's travel is no trivial task, it's doubtful unless it's been through a shop.

 

Anyway, go to MTBR for susp tech support.

If you want actual help I would personally recommend a suspension service centre

I heard a rumor that this new ebike from Specialized can toggle between class 1 and class 3. If true, this blatant disregard for land and recreation managers from one of the United States' biggest sellers is pretty sh*tty.

And yet entirely in keeping with the overall industry ethos.  My biggest initial reservation on ebikes was around their potential implications for access.  Rules vary a lot and in their quest for sales I can't recall any company providing any sort of guidance on potential "ethics".   I recall one manufacturer taking a fleet of Ebikes on a dealer demo past a "no motors" sign in Whistler.....

The implication that users will self police themselves is naive at best and disingenuous at worst...

Any rumors on a new Propain Tyee? Surely it’s going to get frame storage like the Spindrift is and they’re blowing them out right now.

The tyre is new, it’s got to pay for the molds first, the next one up is the Hugene to be renewed

Love the paint colors, and the frame looks very svelte even with their in-frame storage. Hoping the geo is better in the larger sizes, especially the stack to reach ratio 🤞🏽
