fully adjustable suspension linkage

Post by Spike16 »

Ok im thinking of making myself one and was wondering if anyone else would be interested in them?

these would either be made for left and right threaded female rose joints on a threaded bar with lock nuts or if i can get enough orders I could get some turnbuckle linkages made up to the right length with male rose joint ends meaning you could just turn the machined turn buckle to make the linkage longer or shorter

Just incase anyone was wondering these would mean you can adjust your rear ride up and down to suit, lower for shorter riders and raising to get faster turn-in to corners and better handling. these will be full adjustable and easy to adjust without haveing to remove anything from your bike to do so

I had a little look and in my local ducati dealership they sell them for duc's and there £275!!! from looking at costs mine would be around £40-50 (cheeper the more orders i get and weather I can have the turnbuckles machine up)

Who's intrested?

yeh iv seen chris's and if it would be made from female rose joints then thats pritty much what they would look like although his has to be removed from the bike to adjust it

if i can get turnbuckles make up then it should look a bit nicer, this is a turnbuckle and it would basicly look like two of these in parrallel with a turned town ally tube joining them. at one end

Certainly a great idea, but not something I'd fit. If it was as easy for Honda/Yamaha/Kawasaki/Suzuki etc to do this instead of the standard issue dog-bones I'm sure it would have been done by now. Even lowering/jack-up kits are solid steel. My biggest fear would be the stripping of threads due to abuse and where would that leave you. As the manufacturer you would be liable for claims against you and should the worst happen where would that leave you. The instructions are available to make your own so I'd let those know what they need to buy and do so that they can do it themselves.

Good point, well the kit would be sold as componants and not for road use etc and the original link is just made from pressed steel welded to a tube, so strength wont be a problem considering the turnbuckles as machined steel but i apreciate your concern and tbh i hadnt thought of it

I made a set of these, from what was a Rick Oliver lowering kit (two female rose joints and treaded bar X2 and a alloy spacer). a great kit, but only good for lowering your bike, when raising the rear clearance issues with the exhaust pipes come into play. Because of that I modified the kit, so that it's basicly a plate welded to a treaded bar (M10 bolt) that connects to the triangel, this leaves me with the same clearance as the original linkage which allows the ride height to be increased.

If anyone wants a pic or maybe a drawing, please say so..

side notes:
changing this link, ie; shortening it, not only raises ride height, but also changes the rising rate of the rear suspension.

As many know already, the RVF link is 5mm shorter than the VFR link, making it ideal to regain lost ride height when swapping to a 17" wheel. A secondary gain is the increased progressive effect of the rear suspension.
(the rvf link will add 15mm of ride height to the VFR)

Having had a wonderfully set up VFR and then switched to a RVF, I was bummed that the rear simply wouldn't work right, even with the shock from the VFR on it.
It was suggested to me to try modding the pull rod ( link in question) to paralell waht was done to the VFR.
I had the hole welded up and redrilled it 2mm shorter (108mm c-c is stock).
I gained 6mm of ride height, which I didnt need (adjustable length shock), but WOW! The rear end came to life! It settles out right away and is gives a lot more feedback.

Point of all this is just to let people know that there's more effect happening than just changing the ride height....
