Yes, the Suzuki is a known quantity. Here are my three proven options (1978 Kawasaki Z1000, Triumph 900 Legend, Kawasaki KLR650) - the first two probably hard to source. Mine all run with 17 inch rims, but any wheel builder can accommodate whatever rim you want.

Thanks, that's good info. Interesting place for the calipers, but, hey, it works!
They all look good. Pictures sure help.

Cant see any reasons they wouldn't. I'm thinking set the hub up for the chain run then centre the rim accordingly by having it laced off set if need be. Find a nice 18" ally rim to lace onto the hub. Go for a 3.5" so you can run wider tyres. Think Vince uses a 140 on his wider rim.

I have a 140 rear tyre on my 3inch rim. That's the biggest Borani style rim that's made, you can get different sectioned alloy rims that are made wider but I wanted Borani section type. It's a touch undersised for that tyre but in reality, it measures up 5mm smaller when fitted. I have no handling issues that I have found doing this. Which reminds me, must check my tyres for the coming Snowy Ride. BTW that 140 T31 Bridgestone is the smallest Radial tyre available.

Decided to get this, now to get it to fit.
Well, at least if it doesn't work you have a spare for your DR650. It'll work though. It just takes some nutting out, like my Ducati hubs for my GSX1400, and on my 880SFCK.

Yeah, just might be the excuse I need to justify a bigger lathešŸ˜‰.
I found a top guy nearby that can build spoke wheels if I need him too.
These covid lock downs have some advantages.... if you can't ride, wrench.

Good move.
The 'odd' caliper placement was my underslung reverse linkage suck-it-and-see pro-squat design - worked so well i never needed to change it! Only works with SF swingarms, as they have more width. SFQ has a more conventional underslung parallel torque arm (neutral squat).

Yes, the KLRs have 17 inch rears - mine had a chrome Takasago rim on it (older model than yours i'd say). I had to use a spacer for the rear disc to get enough width for the torque arm to clear the 160x17 inch rear tyre. I've ended up not using that hub yet.

Hopefully the hole pattern for the rim will be fairly easy to replicate in an 18 - might even be able to source a 3 or 3.5 inch alloy rim for the KLR hub ready to lace?

I did all my disc carrier and cush drive machining on my little Emco Compact 8 - only swings about 105mm (max 210mm OD circles) - and that was fine.

If you want any help or advice setting things up for it, just PM me. Out of interest, what width is the rim on the hub you bought?
