Good evening,

Did we ever get a definitive answer on what knuckle/linkage to use?

I remember a few peeps trying and suspension was rock hard or solid.....

Answers on usual fag packet please :)

Stock linkage and dogbones, with bespoke bottom mount on the frame works best. Ridden on with shorter dogbones with the linkage in the stock position on the frame; unrideable, and that's putting it mildly. 

There's a few around which make what you need, it's pretty much bolt-on.

Hi! New here! I'm putting a Gen2 Busa extended swingarm into a L model gsxr750 frame. I've heard that it's works better with a custom bolt on lower shock linkage adaptor. I've heard that danm54 makes these. I want to run the stock Gen2 Busa shock and linkage....would this be possible with the said billet adaptor? Cheers. Could someone please put this message his way if he's still on here. Thanks. :)

Use one of these with a k series knuckle.

Dog bones depend on ride height and swing arm length obviously.

Got some anodised matt black as well.

Hi Danm54, 

I had heard of these mysterious Adaptor plates as i was searching for information on fitting a 750K1 arm into my 1100K Slingshot. At the moment I’m going down the route of K1 arm, Standard 1100K knuckle, shock and shorter (130mm) dogbones. Just awaiting some parts to get it all together.

Ive heard conflicting advice that i need this adaptor (but what Knuckle), run with 1100k set up as above but softer spring? So my question is, do you still supply these, which knuckle, and how much please? Tia

Doe anyone know if Dan still makes these as I could probably do with one as well for my WP, Also does anyone have the dimensions of one so I can see if it will fit my WP since they were designed for oil boilers and not water boilers?

Just following up on this as I'm not sure if Dan still makes the adaptor plates, the alternative is a new softer rear spring, so my question is do we have or know of any spring rate charts for standard bikes or easily available "alternative" rear shocks?   I've seen the shock length chart but that doesn't cover spring rates.

Yes Dan can still get these Adapter plates, i ordered one at the weekend for my 1100K with 750K1 arm

I too am aware that you can change the spring to a softer one, i believe MeanBean did this some time ago on his race bike. 

However i hope that fitting the adapter and a knuckle for a 600/750/1000 K1 has got to be simpler than hunting down and trying many springs, then tuning the shock unit to suit?

Good luck on your search for the correct Spring. I had heard that a CBR600 unit worked?

Remember that the damping forces are also influenced by the link ratio, not only the spring rate. Therefore it is important to get the link ratio correct to get the rear end to work in a safe manner :-)

Thanks Guys, I'll chase up DanM and see if one of his adaptors will fit my bike, if not then it's probably time for a custom shock.

A custom shock will not solve the problem. You must sort out the link ratio. Than you can use a rear shock from a gsxr 1000 K5/K6 or GSXR 600 K6-K9.
