DR650 Suspension & Height - Lowered???
« on: April 12, 2013, 04:52:00 pm »
Can anyone tell me if these are the stock dog bones or if they are lowering links?

My DR feels low and I would like to put her back up.

The link looked like the OEM one.

I quickly ran down to my garage to measure the link. The 114 mm is the original link length. :thumleft:

I noticed the "spacers" underneath" the sidestand. Did you buy a DR that was lowered before? ???

The shock bottom mount is correct, in the lower/high seat position. The bottom spring collar appears the right way around.

I also measured the distance from the bottom of the collar to the centre of the open bottom shock mount hole. 45 mm.

Has the pre-load been cranked up again, if it was lowered?  Have you measured the sag on the rear suspension? Let the bike stand upright, and lift the tail with your hand, and measure the difference. How much is it?

If the bike was pre-owned, the suspension could also be damaged.

If it was lowered before, the internals of the front forks might also have been altered! The DR has beeen design like this. :thumleft:

You're welcome to ring me. LeCap is the real expert on DRs. I have had a few DRs, including 2 DR 650s, 2 DR 200s and a DR 250 Djebel. I have the  manual for the DR 650.

Oh awesome. This is an inappropriate hour to call so for now I will type away...

The DR was previously owned twice. Making me the 3rd owner.  ;D Only natural that there are a few complications.

My reasoning to thinking it was lowered was because of the suspension...

So I'm still in contact with the previous owner who said that he already did stiffen up the rear suspension, but it still feels super soft. Like really too soft.
I'm trying to figure out why. I weigh only around 70kg so I shouldn't really have to complain about suspension being too soft.

 I would fiddle a bit more with the suspension myself but I don't have proper tools or know-how to do something without clear instruction.Not sure if it has been lowered or adjusted; have no experience or other bikes to compare it to.

Anyway so I did what you said, and measured the distance from the bottom of the collar to the centre of the bottom shock mount hole. You got 45mm, I got somewhere around 55mm. Which would actually mean mine would be taller  ??? So I'm thinking that I measured the wrong thing so I attatched this pic:



Is that the bit you were talking about? It looks stock to me, so might you have misread the 45 instead of 55? I double checked mine. If they are different then that is worrying.

Anyway I also tried to measure the sag and..... there's none of it. If I try lift the tail there is absolutely no give/sag before the entire swingarm and wheel rise off the ground.

This could all mean that it HASN'T been lowered, which I wouldn't know because I have never sat on another DR. It just feels low because of the soft suspension.

You are welcome to bring it round - and I will have a look at it...

Oh thanks! Where would that be?

The measurement could differ because the bottom collar of the shock can be installed the other way round. That will change the initial pre-load of the spring.
The fact that there is no static sag has nothing to do with the bike being lowered or not.

Awesome that Superfoxi has offered to help you! :thumleft:

He's a suspension specialist, and knowledgable on Suzukis too! :thumleft:

Both me and you measured correctly! You measured to the bottom hole (with the bolt in) and I measured to the top hole (open hole). I am Afrikaans, and might not have expressed myself correctly. My apolagies.  :thumleft:

The collar is therefore the correct way around, and your bike set up for the high seat position. :thumleft:

I ride a '99 DR 650, and my wife had a '08 previously. I had the shock part overhauled, and re-valved for my 95 kgs, and I serviced the front shocks, and replaced the front springs with progressives. My rear pre-load has been turned up quite a bit, with still a bit of sag. My bike has an aggresive/high stance, and feels slightly stiff. Perfect for me.

I reckon the rear spring is designed for a Japanese rider. Is should therfore be perfect for you. Maybe there is a non-standard/soft spring installed, or the spring might be buggered?

With no sag, it seems that the pre-load is already on maximum.

You can still phone tomorrow afternoon from about 13:00, only to do a few measurements for interest sake.

Go and speak to Superfoxi ASAP! :thumleft:

The measurement could differ because the bottom collar of the shock can be installed the other way round. That will change the initial pre-load of the spring the maximal travel of the shock by moving the end stop bumper closer to the damper housing.
(This is necessary when lowering the bike else your brake caliper will bottom out against the silencer or your rear wheel will disassemble the inner wheel cover - not sure which comes first).
The fact that there is no static sag has nothing to do with the bike being lowered or not.

;D

The bike not having static sag does not necessarily mean anything.

How far does it sag when you're sitting on it? (it should sag some 6 - 8cm)

Thanks Superfoxi and chopperpilot. I don't have my license yet, but will try and make the trip when I do.

Hi lecap,

If I sit on it - it does sag about 5cm. Since I am fairly light I guess that is right? (70kg)

How would one raise the height of the bike? Are there recommended measurements or settings? Should one get shorter links?

Don't raise it. You're going to open a can of worms. For your height the bike should be more than tall enough unless you're a toothpick. The OEM rear spring should be absolutely perfect too. Better front springs I have in stock :D

Agree fully with lecap's advise! :thumleft:

The DR is fine for my 95 kgs! :thumleft:

I have the progressive front springs from lecap! :thumleft:

Hey R,
the only adjustment I made to the rear suspension was to turn up the preload. When we got the bike. out was turned right down and would sag almost to the point of falling over if it was not on level ground.
I turned it up till it didn't sag anymore.
if I recall correctly there is still a bit more to go, not sure how much more one should go but I think the more preload the stiffer their the ride. Just getting rid of the sag made a massive difference.
Life ....  when I was younger I had all these cool brave quotes and tag lines .... then life happened  ... and I have no socialialy acceptable  words 😶

Please note the spring must NOT be preloaded to the full length of the adjustment thread as this is way beyond the point where the spring will go coil bound when bottomed out. Should the spring go coil bound before the damper bottoms out chances are good that you destroy your shock. The max. allowed preload of the spring is given in the workshop manual. (Thinks it's 238mm, tbc.)

The more preload the less negative travel. The ride does not get much "stiffer" (beyond the influence of the progressive linkage operating at slightly different angles).

Too little negative travel / too much spring preload will result in poor traction and poor directional precision if cornered hard.

Lecap is correct

Mine is on its stiffest setting
