Anyone here had much to do with suspension-linkage "dog bones"? I've never had anything to do with them but I'd been under the impression they'd be cast unobtanium with nitride-infused micro-peened diamond-coated surfaces and I was just looking through some forums and I saw a bloke just saying you could knock up some custom-sized ones with some bits of steel, a drill and an angle-grinder. Anyone made their own (or know any tales of doom from people who have?) Cheers ..... Clem

A guy in the UK makes them for the SV from high grade stainless steel.

The ones on the FZ1 look like 3mm steel - they must be a tension member cos they look mighty flimsy to take much compression without buckling
You would get a good idea of the material by scratching it - probably mild steel, unlikely to be hardened as that would increase the risk of fatigue failure???

The only dealings I have ever had with dogbone links are Kouba lowering links. They are pretty light and don't look particularly exotic. According to some blurb I found they're made from 6061-T6 Aluminium alloy. Wikipedia says this stuff has a tensile strength of at least 42,000PSI.

Christ no; I know as much about metallurgy as I know about making women happy! I'm VERY impressed by the story though; it sounds like an excellent example of a jury-rig and, coming from a long line of people who'd do almost ANYTHING to keep going rather than admit defeat, my hat is most-definitely doffed in his direction! -- Clem

I have made up similar items on a CNC Machining Centre.

Loads of them on american ebay for just about everything. Stick in lowering links in the search box.

I think you'll find it's aluminium for lightness rather than strength - I can't say as I've ever read anything to indicate they need to be super strong, obviously as a suspension member it needs to be reasonably robust, but none I've ever seen have been super big or made of unobtainium AFAIK

...and come up with motorcycling's equivalent of low-profile 4WD tyres. That so many outfits offer such abominations is testament to how simple they are to make.
The ones Kawasaki and Suzuki tend to use are literally just a pair of lengths of 3mm steel with M8 clearance holes at each end. Could knock them up on a mill in a matter of minutes.
The single chunky dogbone Yamaha, Honda and Triumph tend to use is more elaborate; alloy (on both my R1's they have been, at least) with pressed-in bearings. Bit of machining involved there, but still doable.
All operate in tension, so there aren't too many demands on the metal...
On 2009-11-03, GB (aka Bruce) was almost, but not quite, entirely unlike tea:

Pssst. We have a $100,000 washing machine at work that no one uses. One of the guys threatened to buy a dryer, and the operations manager nearly had a breakdown over that and then resigned.
All the workshop guys did their 3 days training on it, and now no one wants to use it.

I looked at such things for the NOrge but was told they would make the centrestand unusable.

At some point it would be unusable
It is guaranteed to be harder to get the bike up on it as you would be starting with the stand more horizontal and moving further vertically
A bit of triggernometry and a tape measure would tell you if it will work
