Rear paddock stand - Bobbins

[Nasher]

Been having a good look over the M900 I picked up from Blah Blah today and realised it doesn't fit on my paddock stand as it doesn't have any bobbins on the swing arm.
I don't like using the cups as I find bikes slide about on them.

It appears to have to welded in bushes with blind holes of 8mm dia, which I assume I'm going to have to drill out a bit before tapping them to M10.

I'll be machining up my own bobbins in my lathe, but am surprised the swing arm isn't set up from the factory to take bobbins, or am I missing something?

Thanks

Nasher.

Looks like bobbins in this pic

What you can see is just the bosses, they are too narrow with a very thin lip on them that's not really strong enough in my opinion.

Unless of course that's what everyone uses as bobbins, I am completely new to Monsters and Ducati, so am here to be corrected.

Yeah, I'm pretty sure that's what a bobbin is on a monster. They were welded to the swing arm from the factory. Haven't got one on mine as it's a steel arm but my spare ally one has integral bobbins

Yep, that's what I have.

I think I'll stick with Plan A and turn up some bigger ones that will be easier to get the stand under.

Thanks for your help Dirty.

Probably a good idea Nasher, it will save the paint on the swinging arm if nothing else.

Assuming that you are only going to bolt your big bobbins on for lifting and not ride with them?

I've got a hollow rear axle on my SS, the same as many of the monsters. I dint want to drill or damage the swing arm so I bought some steel bar to go through and cut it to length, threaded the ends and fitted bobbins on to each end.

Looks like this

In a similar manner, I turned up a couple of shouldered pegs which fit inside the hollow spindle and stick out enough to get a stand underneath.
Actually, I don't use a stand at all, but a pair of ancient screw jacks, which makes it a simple, one man job to lift the rear of the bike with absolutely no worry of it falling in the process.
But obviously, the problem with this is that you can't remove the rear wheel.

I've still got a conventional stand with adapters which fit under the swing arm, and an Abba stand. The stand in my pic can only use bobbins though and I like it as it has wheels on to move the bike around.

I've done a similar thing to Gilps on my race bike but it has a solid rear axle and so I drilled and tapped an M6 thread to take a pair of bobbins for ease of use trackside but I still need the under footrest lift to take the back wheel out though.

On my 900 Monster I have the same welded bobbins to the alloy swing arm and they work perfectly with the original Ducati paddock stand and once the spacing is set there is no marking of the swing arm itself.

Is a bog standard 851/888/Monster alloy swing arm those bobbins are perfectly adequate for the job in the 27 years since they started to produce that arm I have never heard of any breaking from use with a paddock stand, that is what the factory put them there for!!!!

The same arm with same bobbins on my bike have been in constant use since 1997 and are still going strong, absolutely no need to modify in any way..........unless of course you just fancy a change :)

Nothing can be simpler than a proper paddock stand,and if used correctly there is no danger at all of it falling at all.

Thanks guys.

I think I'll still put some small additional bobbins on there to make it easier to locate the stand.

Although I might have to have a rethink altogether as I've realised tonight that the uprights on my 'universal' paddock stand are going to sit right under the exhausts, and I'm in danger of the two coming together if the dangly hooks are too long.

[Nasher]

Well that's that idea :cens:

If I leave the bobbins in place, even small ones they will clout the exhaust when I go over bigger bumps.

If I put them on just to lift the bike, and fit 'dangly hooks' to the stand, the stand itself touches the exhausts.

So I'll have to cut and weld my stand, and/or use the existing bosses on the arm.

For the time being I've lined the cups currently fitted to the stand with rubber and am using it as is.

I use a rear stand on the small bobbins on my M900 Sie with no problems . One thing to watch for if you intend to extend them is clearance for the exhausts when the suspension compresses . I have carbon Termies and there's very little clearance . Good luck and have fun....
