Last year I sold my motorcycle lift table and bought an Abba SkyLift, seen here:

It lifts by the swing arm pivots, left...

... and right.

It was an excellent choice for my one and only bike... and then I bought a K75. Abba doesn't make adapters for it - their official response is "our records indicate the bike does not have an accessible swing-arm pivot & the single sided Arm is on the wrong side for the lift."

What the K75 does have, though, two beefy m10, 8.8 grade rear engine mounting bolts located in the same plane.

Assuming I could make adapters, which would look something like this:

I could lift the bike that way. Theoretically.

I am not a mechanical engineer. Anyone want to chime in on whether it's safe to lift the bike by those bolts?

I'm not an engineer either, but your proposal looks marginal to me.

If you do use those mounts, you can't remove the gearbox for rear main seal or clutch replacement....

I took a long look at these when BobT showed me his as they are great space savers but I came to that conclusion also, that you couldn't do a rear main seal or gearbox job with the sky lift. Hence my conventional bench lift was bought.

I've been looking at this, I have a skylift and a newly acquired K100, I was thinking of machining up something for the front engine mount bolts and use the front lift arm kit they do but backwards so it holds the front of the bike down keeping the back up

Failing that I was looking at getting the cruiser lift attachment.

That's an approach I hadn't considered... very interesting. I also had not considered the cruiser lift... though it is awfully pricey.

Do you think the engine bolts would take the strain?

you can buy the cradle separately, still expensive for what it is could probably make one myself.

I will nock something up this week if I have some bar stock in and trial it on my Superbike stand see if it falls over if it does its not that far to fall. 

I reckon the bolts will be fine although the adaptors I'm thinking of making will go over the bolt head rather then sit in the Allen key bit.

I had some success making adapters out of 8mm hex sockets I found online. I did have to trim them down and shim them with heat shrink to fit... lawd, I wish I had a lathe so I could make something with a better fit.

It's certainly good enough to get the back raised, which will make working on it a lot easier. And once it's up on boards, I can disengage and remove the lift.

I bought this collapsible steel sawhorse at Lowe's for $20 about 15 years ago and I use it through the middle of the frame to do all of my spline lubes. It takes up very little storage space (it collapses to the size of a 40" long 2x4) and supports a K bike very well. (Rated capacity is 1,200 lbs.)

Could you not use the Abba swingarm kit on the footrest hanger bolts? This is how I lift my NS400 Honda - admittedly a much lighter bike - but works a treat. I have pics of it in use if any help?

This is how the swing arm kit fits to my NS - I can use either of the hanger bolts.

Thanks doc! I had not seen them up close before. I asked Abba about them and they said the swing arm kit is only suitable for lifting the rear end... it's reasonably priced for what it does. I haven't checked if the K75 has the right sizes bolts for the swing arm kit.

No worries.... the 'bobbins' take an 8mm allen bolt, but I reckon you could open up to 10mm if required.

After trying the approach with hex sockets I think you are spot on - it's much simpler to make adapters that go over the bolt heads. I don't have a lathe but I have an uncle who does - it'll be a pleasure to work on this with him. Here's my design:

You will have to be very careful if you engaging with the outside of the head of the allen bolt - what are they - 10mm deep? It wouldn't take much to slip off... std abba adaptors are 20mm plus giving a much better engagement with the stand/lift

Agreed. But I am confident that the tension applied with the screw on the right hand bar will keep things secure.
