GB #2: '06-'08 D675 Rear Suspension Correction and/or Ride Height Plates *CLOSED*

After the unmitigated success and well received reports coming from the first group buy, I'm offering a second group buy for the suspension linkage plates. This time I'll make sure the 10mm drop height plates get machined correctly (sorry about the delay guys) and try to make this effort a little more streamlined.

--------------------------------------------------

Click Here for full details on what these plates are and what they do

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, and until such time that I close it (which will be on Monday 11th May 2009), you can just extend the list with your name and I'll get that amount of plates made up.

It will take around 4-5 weeks from the final closing of the batch until the plates are machined and ready to be shipped.

20mm Height Reduction Plates*

* 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.

Update: The ordering process is now closed and this will likely be the last batch I do. I will have some added spares made up though for late comers. Expect the completed plates to me in my hands and ready to send out to thos on the lists in approx. 5 weeks from now.

Unsure if you're asking me questions that were already answered in the opening post either directly, or through links to the previous GB thread with user's testimonials towards the end of that thread. Perhaps you could be a little more specific with what you want answered if the OP isn't providing the information you seek.
