We have been running a Suzuki DR650 suspension special with the ADV Rider forum for a while, and it's hugely popular! We like the DR and it's workhorse like nature. Our aim is always maximum performance at minimum cost, so we offer these special prices for the packages below only.
Every option is sprung front and back to suit you and your application. Every shock option is dyno tested on our suspension dyno to ensure it meets our standards. No matter what you use a DR650 for, we will supply a package that works.
*Pricing based on a new or as new bike. If you need consumables, seals, bushes, bumper, shock seal, shock shaft, you need to pay for these consumable parts. The service won't cost you more as we already have the suspension apart.
Pricing does not include freight to and from our workshop. We use AusPost, TNT and Toll. almost anywhere in Australia is $25-35 one way, road freight.

Early model DR650's (1990-1995) used 41mm Forks, while 1996 on DR650's used 43mm Forks, both of them Kayaba Conventional units. There are differences, but both are very similar in terms of the way they work, so they end up getting the same kinds of tuning. And we stock a pretty darn big array of spring rates for both forks.
We also modify the damper rods and fit our V4s valve (our version of a Race Tech Emulator, PD Valve, Travel Control Valve, whatever you want to call it), it gives a speed sensitive dampening character to the damper rod fork. Like many of our parts it's made here in Australia. We have a lot of very happy customers running around OZ on this set-up, it's robust and well priced.
The DR650 shock can't cope with any additional weight over a 75kg rider, the stock spring is really light and the dampening is minimal. The shock is a 40mm KYB unit, compression adjustable only. While it's not the "trickest" shock out there it's a very reliable unit and easy to service and modify.
We have used complete shaft assemblies with pistons, Gold Valves and the like but it adds to the cost and did nothing for the performance we couldnt do with stock parts. After a lot of testing, both in the shop on the shock dyno and with selected customers, we have a shock setting that makes whoops out of Finke manageable, does not beat you up on an 800km day and makes the DR a whole lot more fun to ride. This revalve uses the original piston, and we think it beats the stuffing out of the American Race Tech piston and shaft conversion. We don't make the rebound adjustable as we don't think it's required and just adds to the cost. As the great Laurie Alderton said, "You don't need 40 clicks of adjustment; you only need one, the one that works!" Ours works. No gadgets.
We couple our shock mod up with a spring specially made for the DR650, so no spacer is required and you get plenty of preload adjustment.
Some riders swap out the forks for DRZ400 units, but the triple clamps have to be swapped as well, because the fork size is 49mm. You need to run the 400 wheel too, as the axle is bigger, or make up a custom axle and spacers. After all that, the DRZ's fork springs are only 0.44'skg/mm, far too soft for most people, so you end up spending more money on harder fork springs. The stock 650 disc is bigger than the 400 too.
The DRZ400's shock is better, being a 50mm Showa. It needs quite a lot of reworking to the linkage knuckle on the 650 as it's narrower, requiring milling and a bearing that's not easy to get. Added to this, the spring series is different on the DRZ400 shock, so the stiffest spring we regularly stock is a 6.8kg/mm (20-115-68). Plus the shock needs a revalve to be as good as our modified stock DR650 shock. The advantages are that you have are a rebound adjuster and more oil capacity.
Think very carefully about what you want to achieve before diving in.
