can you use SF2 spoke wheels on 3CL/Jota bike

Hello, Mingh.
Gerald changed to spoke wheels on his 3CL.
He used a SF2 front-wheel, but on the rear he
used another solution with Suzuki parts.
The rear hub for spokes in combination with
a disc is very hard to get, imho the rarest 750 hub.
See Gerald's illustrated description on JLO's website:

Doing that right now.
First thing I noticed was the front wheel spacers are different.
Second thing I found was that the rear caliper carrier/spacer was all wrong for the 3CL swingarm when the wire wheel/disc was in place.
Seems you need to fabricate an underslung carrier for the caliper and use a caliper from the other side (RHS vs LHS or vice versa)to make it all fit properly.
This is where I am at currently as I am busying myself on more immediate Laverda restorations.

No. Nothing to see yet, just cobbled together with spacers to allow me to move the bike. 
Once I get round to it I will give it some more thought.
Pretty sure I could get the original carrier/spacer to work with a bit of huffing and puffing (and a big bastard file), but we'll see.
3 other bikes to be attended to before this one.

The spoked rear hub "commonly" available for these conversions is slighly different concerning disc spacing. The original bracket as used with the cast wheels will not fit and due to the proximity of the rear shock, there is not enough space to fit the caliper atop the swingarm. Moto Witt supplied special brackets to mount an opposite-sided caliper under the swingarm, not sure if todays' suppliers of these hubs do that or if you're on your own.
An alternative would be a hub from a 80s jap bike, Honda 750F1, Z1000, GS750/1000 spring to mind.
Am currently looking into making a DR650 hub fit....

Is there an alternative spoked front wheel hub other than the SF2.
I'd imagine the SF2 is difficult to get hold of and expensive.....
Would the hub from an early 70's CB750 fit or GS750 fit..........

I don't know if you've looked at them but Andy Wagner does sell a f/r pair of spoked wheels designed to bolt straight on with the Laverda discs and calipers. I haven't seen them myself but afaik nobody's said anything negative about them.
Although coming from Andy they will be expensive, it depends on how much machinist time you have to put in (or pay for, if you're like me). Just about any 18" wheel can be made to work if you're prepared to put the time in. Something else to bear in mind is that you might want to consider wider rims designed for tubeless radial tyres, hard to do with spoked wheels but not impossible.

For ease of installation, I'd stay with the Laverda front hub.
The speedo drive can be taken from the cast wheel, means the speedo will work correctly, axle and discs fit without messing around. And easier to replace should something stupid happen...
I use as many Lav parts as I can in my conversions. If using items form other bikes, I try to keep things as simple as possible in order to be able to replicate/repair quickly and cheaply. If you build yourself a complete one-off, it's going to cost, and if it is damaged, a simple shunt can be enough, you're going to start all over again.
One-offs are quite OK for bikes that reside in a glass display case, but our bikes are meant to be ridden, aren't they??
Ken,
AfaIk, the Wagner kits are copies of the old Witt kits. The space problem at the rear can only be solved if the base width of the spoke flanges is reduced, giving the disc space to be located closer to the centre axis of the bike. The spokes in these wheels are already on the long side, and narrowing the flange base width will compromise the overall strength of the wheel.
After experiencing spoke durability problems at the front as well as bearing spacer and spoke problems at the rear of my 3C, I replaced the SFC 1000 spoked wheels with the considerably lighter and stronger GSXR rims. The spoked wheels are quite OK for sedate touring or tootling around the countryside, but for serious hooning they just don't cut it for me! What's more, the looks of the Suzuki wheels has grown on me and I no longer really miss the spokes.

Here is my spare rear disc hub,just waiting for the swingarm to rot through so its easier to remove these front hubs might modify for thr front.

Excellent hanging basket . I think the chains must be Andy's quality as they haven't rotted off yet as for the basket when its empty I was thinking of wearing it as a helmet when riding our ex wd Norton 16h.
