HO322 NOT available anymore

Gents,

For those of you who were considering purchasing an HO322 in the future - it's out of production. Sad news.

So...before I spring for the 201 - I don't suppose any of the 322 owners out there are considering an upgrade and would be willing to sell me their shock...?

Of course, if anybody knows of a place that might still have them - but I understand nobody stocks these things; they get them built to order, right?

Cheers!

You might try calling LDH at Dan Kyle Racing before throwing in the towel (831)394-1330

I have, thanks. He was actually the first guy my own suspension dude called.

While I've never been able to latch on to a set of damping force curves for the HO322, I have certain sense that they are low speed compression valved for the particulars of the 919. If you can't find one, don't waste your time on anything less than a 3 way that has a low speed compression circuit that can cope with the squat force of a 919. The unlinked rear suspension and flattish swing arm angle really conspire to create the need of lots of low speed compression damping force. Keep in mind that most "custom" shocks out there these days are conceived for linked rears, which see only around 1/2 of the spring energy and squat force at the shock, in other words their normative damping forces are around half of what's needed for a 919 that is being pushed on a track.

MC, as usual, thanks for the detailed and informative response.

Anybody heard of the Daugherty F4 shock upgrade? While I was re-reading some threads here on the forum, hoping to find a supplier for the HO322 - that's when I learned basically nobody keeps these in stock - someone suggested Daugherty, although I believe it was for Penske. Either way - I contacted him, and he suggested, if I was on a budget, his custom-pistoned CBR600F4 shock. 350$. Spring and internals adjusted for 919 and rider weight.

I seem to remember someone here on the forum had one (hondad, I think...?). I know LDH and others might pipe up in here about OEM shocks being crap, but I think these are significantly re-worked internally. Either way, the problem is thus : Now, with the departure of the 600$ Ohlins option, one has two options :

1. 350$ for the Daugherty one, or a bit less for a rebuild of the stock 919 shock;
2. 919$ for the Ohlins one.

Yes, I know I can get a Penske 8900e for 600$-ish - but that's an emulsion shock, and I've been steered away from those by two suspension experts I've talked to, Kyle of Windmill Motorsports and Willie Vass. Would they be better than the heavily-modifed F4 shock? Don't know.

If I take into consideration the Canadian dollar, and how it's absolutely plummeting right now, it turns out that my 919$ Ohlins (no offense to LDH and Dan Kyle - I appreciate this shock at 919$ is still a fantastic deal!) will be closer to 1300$. That's starting to hurt. I'd already sent Windmill 750$ CDN for the HO322 (he'll refund, no worries), but I'm really having a hard time spending a further 550$ on the 201.

I'm sure I'm not the first to think of this, but - is there another Ohlins shock that could be made to work for the 919, that could be more affordable? I know, I know, EVERYTHING could be made to work with enough time and money - I mean, a shock that could be made to work relatively easily, let's say. Or would that be pure heresy?

To be clear, I'm ready, willing and able to spend about 550-600$ U.S.. I already have. =) But that's kind of the max I've got.

275.00 + shipping. He lets you pick the spring rate.

If the F4i shock eye to eye free length is the same as the F4, then run and hid unless the shock can be shortened.
I fished about and found a post elsewhere that looks quite well documented and says the F4i free length is 306 mm.
If it can be shortened, I would not shorten as short as 919 length, but instead leave it longer in order to allow a 10 mm Free Sag with stiff enough spring to get a decent rider sag number while also lifting up the rear to get improved swing arm angle, more ground clearance, and elevated C of G height.
Of course the front would also need to be lifted accordingly.

For what you are clearly out to do, the 8900e is a worse than a waste of money.
Remember too that haste makes waste, and the end of the season is nearing.
Why not use the winter to see what bubbles up re used stuff, then decide by Feb or March which path to follow ?

A bit more elaboration is needed re the above.
The idea of using an adjustable shock length is to :
*Allow use of the most ideal spring rate.
*Be able to set up the top out softer by using light preload.
*Be able to correct for the greater Rider Sag and resultant loss of chassis ride height due to the above 3 elements.
* Elevate the rear ride height for improved swing arm angle to reduce the net squat force.
* Elevate the rear ride height to reposition the C of G higher, to reduce the chassis roll effort required re levering the bike over for a turn.

Agreed on the haste part. What are your reasons for saying 8900e is a waste of money?

Yeah, was starting to lean that way too - wanted it done and complete by end of this season, but that might not work out.

Regarding which modified shock - it can be either F4 or F4i :
