This is a Group Buy to sell off the sets of plates that I have left-over from the first and second runs that I had made. After this lot is gone, that's it for me. I simply don't have the time in my life at present to continue getting these plates made up any more.

Quite a few people dropped out after my extended delays due to family health issues, and for that I both understand people doing so, and offer my apologies.

These plates I have here are already completed, and packaged in envelopes ready to go out the door on a first-come, first-served basis. I've had quite a few people contact me via PM, but what with the delays, I don't even know if half of the guys who PM'ed me even want them any more, so I'm starting afresh.

Okay, so you didn't want to click the above link and still want to know what are they and what will they do for you?

What the replacement plates are

These are drop-in replacements for the pair of triangular shaped rear suspension linkage plates that link the rear swingarm to the rear shock-absorber and the rear suspension "dogbone". Computer simulation and analysis of the stock linkage plates determined that their dimensions were contributing to a less than desirable rising rate suspension action, causing harshness in the ride quality of the bike over bump sequences, and a tendency to pitch the rider out of the seat over larger bumps. The replacement plates were designed to address these issues.

What these replacement plates do

  • Corrects/dramatically improves the harshness of the 675's rear suspension action with the stock rear shock unit, feeling as if the rear shock absorber has been upgraded to an aftermarket unit
  • Rear suspension action is more supple and compliant, allowing for more confident riding over bumpy roads. This also feeds back as better front-end control as well as the rear stops pitching and pushing the front as much.
  • Greatly reduces the tendency of the 675's rear suspension to kick you out of the seat over harsh bumps.
  • Increased rear swinging range, giving greater rear suspension travel. The rear wheel gains about an extra 10mm of top-out (meaning it can extend 10mm further than standard before the rear wheel leaves the road) and around an extra 5mm of travel before full compression (bottoming out).
  • Coupled with a quality aftermarket shock unit, I've personally not experienced a better rear suspension action on any bike.
  • Completely drop-in replacements. In most cases should require no adjustement to the rear shock settings. Ride height (with the rider aboard) will remain the same. In some cases (for hard road riding) increasing the rear rebound damping setting by 1 click will be helpful, and further fine-tuning by adding 1 click to the rear compression setting if required (also for very hard road riding).
  • CNC Machined from 5083-H321 grade aluminium alloy, which is a high strength marine (corrosion resistant) aluminium alloy.
  • Type II hard anodised in a low-gloss black colour
The plates come in a choice of retaining the standard right height, or giving a 10mm, or a 20mm ride height reduction, which may be useful for the height challenged riders amongst us what with the D675's rather tall seat height.

Price

Within Australia:
$68AUD (Australian Dollars) for a pair of plates, plus $4AUD postage + packaging, for an all-up shipped total of $72AUD

Anywhere else in the REST OF WORLD:
$68AUD (Australian Dollars) for a pair of plates, plus $7AUD for postage, packaging, and Paypal fees, for an all-up shipped total of $75AUD

Payment

I'm not a shop-front or store of any kind. This is purely an offering from a fellow riding enthusiast to those interested. Payment via Paypal is typically the best way to get funds to me, or Western Union works equally well. If you're in Australia, a bank direct deposit is the best way to go. If paying by Paypal just select the Australian dollar currency option when sending money and Paypal will perform the conversion and deduct the correct amount of money from your local currency balance. If paying by Western Union, make sure that I'm receiving the correct amount of money at my end in Australian dollar currency.

When I'm ready to receive money (which I won't accept payment UNTIL I actually have something physically packaged and ready to send to you immediately), I'll send out a PM to you requesting payment and re-expressing the details.

Until then the ONLY thing that you need to do is add your name to the following lists. This group buy is open until existing stock runs out.

The plates are available for immediate shipment. When you make payment, they're yours.

I have the following amounts of these plates left. These are hard limit numbers. After this lot, they're all gone.

Group Buyers

Standard Height Plates (19 sets)

10mm Height Reduction Plates* (4 sets)

20mm Height Reduction Plates* (1 set)

40mm Height Reduction Plates* (4 sets)

* Height reduction here means as measured from the rear axle to the ducktail directly above with a ~175lb (80kg) rider + 15lbs (7kg) of full gear seated on the bike. The actual seat height reduction is around 60% of this value. (ie. 10mm height reduction = ~6mm reduction in seat height. 20mm reduction = ~12mm reduction in seat height).

Just quote the list and extend as needed, adding your login name to whatever list you want. You can order multiple plates if you wish and I'll contact you with the final shipping total for such orders.

Looks like i'm too late on this great idea.
If one of the above guys drops out, it's yours.

The actual dimensions are all listed in the original thread (for the standard plates). They are, by far, the most popular, so if someone wanted to grab those dimensions, they can do so. My "plans" basically consist of a hand-drawing with dimensions scribbled all over it, which I handed to some CNC machinists to draw up and make.

These plates are fantastic, [Flux] sorted me out awhile ago with a 40mm reduction height set and they have made life alot easier for me and riding my bike :)

Yeah I think so, probably just busy

I'd get in line for standard height plates should anyone not take theirs :whistle:

I'm about, but have been hiding from the world in general due to several stressful issues.

Just sent you a PM.

I have 3 x 40mm sets left, and 2 x Standard height sets left, for which people had ordered but never paid.

Happy to unload them to whomever reads this.

I don't know if there are any of these left, but I installed them last weekend and they made such a huge difference. The bike is like a completely different animal. It is much smoother and more compliant over the bumps, while still maintaining it ability to hold a line. Big props to FLUX for engineering and producing such a high quality and effective mod :thumbup:

I did run into a small issue with the installation that I thought I would mention because it hasn't been addressed very well from what I can tell. In removing the flex plates, the stock exhaust sits directly in front of 2 of the 3 bolts, partially blocking the heads enough that it blocks their removal. After playing with various possible solutions to this problem, I found that if I disconnected the rear shock by removing the horizontal mounting bolt (not the vertical bolt), it gave me more than enough wriggle room to move the flex plate back and forth to fully remove (and reinstall) all of the bolts. Obviously this is easier with a second set of hands, but I was able to accomplish this easily enough myself.

Cheers!

Thanks for the feedback. Yeah, on both my bikes I have aftermarket exhausts. While it was a bit fiddly with them, I was able to do it without removing the top horizontal bolt by lifting the rear wheel up and down to clear the exhaust pipes.

Simply removing the top horizontal shock mount bolt will make life easier.

hey Flux,

I know I also replied in the other thread....but noticed you still had the 40mm drop plates left. Do they make a big difference in seat height? 40mm equates to about 1.5 - 2 inches. Does it affect handling in any huge way that you could tell? I haven't been to the track yet and mostly just ride public roads and mountains but would love to take the bike to the track sometime in the future.

Just for dimensions sake, and if you have time to help me out, I'm 5'9" 185 lbs.

The 40mm is measured from rear axle to the ducktail directly above. The seat height drop will be around 22-25mm or so (7/8" - 1"). The bike will turn a little more slowly, but this is also countered by the bike's CoM sitting lower, so the effect is not that dramatic. You can bump up the preload though to bring the drop back up to something like 25mm. I have a 20mm drop on my street-fighter 675 and TBH, I vastly prefer the way it handles over the "stock" 675 I have with the standard height plates.

Edit: The one main concern is the side-stand. Drop the bike too low and the side-stand is now too long. Still, starting with the 40mm plates and bumping up preload is a good thing, IMO. It's more or less the approach I'm taking with the new track-based plates I'm working on.
