Ohlins FGR 254

Spooky you wouldn't have a set of these in your office? I'm curious what the valving looks like versus the standard cartridges. You can buy a cartridge kit for $1200 or $2400. Wish they'd actually show the internal parts. Only thing they say is that the cartridge shaft has a smaller diameter.

There’s a guy named John Chen out here that has a direct line to the Ohlins in house engineers, so Ohlin custom spec’d the valving and spring rates on my TTX GP rear shock and my carts. Taking into account weight, pace, and my extended swingarm and linear shock link…they got exact dimensions on both the latter.

Then RoadRacerX here at the forum (local to me) put it all together and dialed in my preload, and initial comp and reb, and got the bike turning right for me.

RoadRacer put the FKR into the FGRT?

I’d assume he put the FKR carts into stock forks. But I wouldn’t put it past Steven that he bought FGRT forks and then exchanged the cartridges haha. But the stanchions on his bike look like OEM (at least from far away). And from what his post says, it sounds like John Chen did the cart swap.

No, FKR into my Nix 30’s, my bike had the electronic Nix 30 forks, we replaced the electronic stock internals with Ohlins custom valved FKR 108 carts. Fairly simply swap, you just need the Electronic suspension bypass plugs that you can get from SBU or HSBK
 
The Nix 30 forks by themselves are not substantially different that the FGR 254 Forks, it’s the internals that make the difference. And I wanted to keep my Sicom Rotors and PADS, so I have to stay with the 100mm calipers. So to get the best of both worlds, i.e. keep my Sicoms AND upgrade the front forks, the best option at the time was to put the FKR 108’s into the Nix 30 forks, which drop right into them btw. You cannot put FKR 108’s into Showa forks, but they plug right into the Ohlins Nix 30 forks on the V4S’s.

No John is just a one man registered dealer with Ohlins, and is an engineer by trade, and a VERY fast track day rider, usually sets the fastest lap times of the day every time I’ve been at track with him. He has some inside track to the in house Ohlins engineers so a lot of us that know him personally get our Ohlins stuff from him, because he gets it setup and reviewed by Ohlins directly. Him and a guy named James Chin are sort of our local ‘Know a guy that Knows a guy’ that all the faster riders refer and go back too.

So ordered my rear shock and carts through John Chen, who got them researched and spec’d/valved/sprung directly with Ohlins, and then had RoadRacerX drop the carts into the forks, install the rear shock and set up my bike geometry front and rear and the dampening.

Made a night and day improvement in how well the bike turns in and finishes a corner.
 
My bike came with showa's. They're hanging upside down so the 90 wt developed for Deere harvester gearbox can drain out. I was going to pour ohlins 1309 in them (why waste the fluid) so ultimately punted and bought a set of S forks so I can revalve to suit. Thanks for the cartridge evaluation. Steven not upgrading from his current set up is high praise indeed.

Did you get the manual adjusters to replace the electronic ones?
 
I'll change whatever needed to make them manual. I just bought the forks when they show up I'll pull them apart to look at the shim stacks. I'm guessing the electronic fork uses a standard compression valve and uses the electronic needle to pop open the low speed damping when it sees a pulse. The 108's probably have the barely hanging on by its toenails sort of compression valve. The new cartridges have the sliding bushings which were not present on the earlier forks. From the pictures it appears they are being used to increase the inflow capability on rebound? Anyway I'll take them apart and take pictures.

You’ll need those if you take the electronically adjustable carts out and put in 108’s…mount them away from any heat sources, they are sensitive to heat. Also do not turn the bike on between unplugging the old fork electronics and plugging the bypass in, or it will pop a code that you can only get rid of by plugging the old carts back in, cycling the power on and off, then plugging the bypass’s back in before turning it on again. Doing it that way avoids some annoying juggling lol

Doesn't NIX30 refer to the cartridge, which is gas pressurised vs FKR which is spring pressurised? Putting FKR carts into an FGRT or a Showa fork is a big but expensive upgrade.

As you say, it's all about the internals.

The electronic motors merely turn a damping rod. It’s not a very sophisticated mechanism for sure. Someone makes new top caps which replaces the electronic adjusters for manual ones, I just can’t remember for the life of me who off the top of my head.

ETA: It's a WRS product.

It’s hard to keep the acronyms and various technical references straight.
