Devol Suspension Dog Bones

I have a set.

They are VERY pretty! ;)

They come WITHOUT required hardware. Well, when I got mine, and last I checked with devol. I tried to get them to INclude the needed parts with their pullrods, cuz getting them sans needed parts stinks. You need a couple of kx250 bolts and washers/shims. PNs can be had from buykawi, or from devol.

The bolts are something like $15/20 each. New nuts (if you choose) are $5/7 or so.

Yes, they noticeably change the handling characteristics. Seat height is about 3/8" lower when the pullrods are installed in the 'longer' configuration. The rear suspension gets a bit more 'linear' due to geometry changes of the unitrack.

Don't forget to reset your sag after install.

If you're on the edge of needing a 5.2kg/mm shock spring, the pullrods installed in the 'longer' configuration will put you over that edge. Likewise for needing a 4.8 and the 'shorter' configuration.

They are quite a bit easier to dis/reassemble during maintenance. The kx250 bolts have a longer shoulder that doesn't have the problems the stamped oem pullrods/oem bolts have.

And....did I mention they sure are purty!!??

I haven't checked their website for months. They may have resolved the 'no hardware' issue by now.

Yep. Stock nuts fit. I wanted the stickiness of new nylon, so I got new fasteners.

Haven't looked, but a decent hardware store would probably have such locking nuts of a metric nature.

I used the shims just to keep the pieces pretty. A lot of people looking on the inside surface of your pull rods, yanno? ;) That and seemed they might help out the grease seals.

I don't recall devol saying they were necessary. Don't recall they said they were NOT, either.

I installed them in the '+' length. I was looking for a bit lower seat height.

The '+' will increase the lever length, thus increase the pressure applied to the spring. So an input of 'x' force will result in increased shock travel.

Hence the 'more linear' comment. Obviously 11" of wheel travel doesn't relate quite to 11" of shock travel in stock trim.

Oppositely on the '-' (shorter) setting.

That's why the longer setting may take a stronger spring. If you're anywhere in the ballpark springwise, I wouldn't worry about it.

Funny they haven't resolved the bolt issue yet. I got mine a couple years ago.....wasn't too happy to 'find out' the rods wouldn't fit with the stock hardware. On the phone, they said they were considering making a 'kit' out of it. Obviously the cost would be higher.....probably not $40 higher considering the over-the-counter cost of the bolts from kawi.

At least you'll have the parts on-hand when you get the suspension apart.

Did I mention they surely are pretty?

so do they improve handleing?

I'm missing something. Re: beneficial/detrimental, I think I'm addressing the question. I am not purposely being obtuse.

Describing the effect was intended to allow one to draw their own conclusions. Opinions are nice, facts are better.

I think the DFII is such a huge advantage over any other reed system. There is no comparison. Others think differently.

I think the XR spring is far superior to any other aftermarket spring. Others think differently.

I think the electrex lighting coil is an engine performance addition. Haven't seen any thinking about that at all in spite of my baiting the issue.

I think a more linear reaction by the shock is an improvement. It becomes more pliant, more compliant to the ground. Devol describes it as a 'smoother ride'. I agree. Consider the whole idea of increased moment arm length and subsequent application of force differences for similar effect and you may agree also.

...but then...I never quite latched onto fissicks too good.

Maybe it's all in my head. ;)
