Well tonight I bought my first DR, and a brand new one to boot. I've been researching for a bit, and #1 mod on my bikes is suspension, it just is the best place to spend time/money for off road. Anyway, there seems to be a huge number of suspension threads for thd DR out there, and often with great disagreements. Someone might claim 0.70 kg/mm fork springs and stock valving is the best, another says 0.46's and emulators flatten washboard and soak up supercross triples. Often times the posters give no real information to weight, riding style, experience, etc.

So why not try to make an organized thread to bring a lot of this together for reference? If this is out there I sure haven't turned it up.


Rider weight
Bike add-ons (big tank? always carry 70 lbs of gear?)
Riding type (gnarly rocky single track? 100% on road? two track? etc)
Riding background and ability (newbie? street rider transplant? ex supercross pro?)

Forks
Spring rate
Preload
Oil weight
Damping (stock? emulators? intimators?)
What did you try to get where you are at?
What would you do diffetently next time?

Shock
Spring rate
Oil weight
Damping (stock? emulators? intimators? shaft swap? etc)
Sag
What did you try to get where you are at?
What would you do differently next time?




I thank you for your time and effort.

Rider weight: 180 lbs naked, about 200 in gear
Bike add-ons (big tank? always carry 70 lbs of gear?) IMS tank, skid plate. Mostly ride solo, sometimes with my daughter @5´5" and 130 lbs
Riding type (gnarly rocky single track? 100% on road? two track? etc) Mostly road, sometimes gravel roads and light offroad
Riding background and ability (newbie? street rider transplant? ex supercross pro?) Experienced rider, mostly street, some enduro-bikes (KTM 500 GS Rotax, KTM 525 MXC), no racing-background, but frequent MTB-rider

Forks: WP48 front end from a Husaberg 2005
Spring rate: Husaberg stock, shortened travel
Preload
Oil weight: 5W
Damping (stock? emulators? intimators?) fully adjustable
What did you try to get where you are at? I tried firmer springs with 10W fork oil on the stock fork, but the ride was too harsh for my liking. Being in Europe having DDC sent to me including expensive shipment, customs and VAT was no attractive solution.
What would you do diffetently next time? Save the time tuning the stocker and go USD immediately.

Shock
Spring rate: about 8 (German Wirth-part that states "30% firmer than stock")
Oil weight: 7,5W fork oil
Damping (stock? emulators? intimators? shaft swap? etc): stock
Sag: approx. 3", symmetrical with fork
What did you try to get where you are at? I had tried spring-only - no noticeable rebound damping. Then went 10W: too slow; 5W: too fast. 7.5W hits the sweet spot, sufficient rebound and compression is now 2-3 clicks from fully open. A full Cogent rebuild must be a lot better, still, but cost-prohibitive ...
What would you do differently next time? Refill the shock with 7.5W fork oil. I had since done this to friend´s shocks and they all noticed a big improvement.

Great idea everyone!!!
I JUST got my suspension tweaked last weekend too.


Rider weight - 185/200 with gear
Bike add-ons - rack, I usually ride with a 10lb backpack
Riding type - Daily driver in town, forest service roads, superslab to get to riding locations
Riding background and ability - all dual sports TW200, XT22, DR650

Forks - OEM - KYB 43C
Spring rate - 0.47
Preload - less than 1/4 " (two fat washers)
Oil weight - 15
Sag - 2.5"
Damping - emulators will drilled out damping rods (2.5 turns on blue springs with 3 1/8" bleed holes
What did you try to get where you are at? (Everything) the racetech website really threw me for a loop when setting up the suspension. I tried 0.6 springs, yellow, blue and silver emulator springs 7.5, 10 and 15 wt oils
What would you do diffetently next time? Call Procycle for help and set up sag FIRST!

Shock - OEM -KYB 40 mm
Spring rate - 7.5
Oil weight - 3 (shock fluid)
Damping - Gold valve (SMGV 4005) two steps lower than recommended dampening
Sag - 3"
What did you try to get where you are at? Spring with 10wt oil in stock internals
What would you do differently next time? all Procycle for help and set up sag FIRST!


Codgent fork valves we not available when I did the front fork and I didn't have the $$ for a more expensive rear valving option.
I must have taken the front fork apart 5+ times and yanked the springs and emulators at least 20 times. Racetech is still the best low budget option but you really want to talk to a DR650 vendor before ordering stuff blind.

Bike add-ons: 5.5 ish gallon acerbis, soft bags
Riding type: mountain single-double track or jeep roads. also street in SM mode.
Riding background and ability 2nd year on dirt after 14 years of street
Forks
Spring rate .47
Preload: what ever it took to get 70mm of sag
Oil viscosity: 5w
Damping: modified cogent DDC

Shock: Riccor
Spring rate: 7.6
Oil viscosity: factory
Damping: non adjustable but a good match to my front setup (ie firm compression not much rebound)

this setup provides a plush but controled ride that works well in most circumstances.

(updated to show recent changes)

Rider weight 300 lbs ready to ride
Bike add-ons (big tank? always carry 70 lbs of gear?) skid plate; wolf fender pack with tools for trail rides
Riding type (gnarly rocky single track? 100% on road? two track? etc) 60% road, 40% dirt. When on dirt two track and technical single track; wherever the trail takes me
Riding background and ability (newbie? street rider transplant? ex supercross pro?) grew up on dirt doing trail riding on a trials bike +10 years; hill climbs, technical terrain, water crossings. No MX. Road is new to me as of 2013. I spend most riding time standing on the pegs; even on tar. I get weird looks

Forks
Spring rate Racetech k=0.58 kg/mm
Preload 8mm w/Cogent adjustable fork caps
Oil weight 5wt, 130mm
Damping (stock? emulators? intimators?) Cogent DDC
Sag 25%
What did you try to get where you are at? various preloads, 0.70 kg/mm springs post DDC install
What would you do diffetently next time? different oil level maybe

Shock
Spring rate k=8.15 kg/mm
Oil weight Unknown
Damping (stock? emulators? intimators? shaft swap? etc) Cogent Mojave Pro Series: 20 clicks rebound, 7 dots compression
Sag 34%
What did you try to get where you are at? Nothing
What would you do differently next time? I want to try 30% SAG out back; perhaps fine tune the compression damping adjustment more.

For noobs or those considering something, just do the Cogent complete solution (or something); you will not regret it. It's like pulling the snorkle from the air box; you will wonder why you waited to do so...
