does anyone know if there is a single sided swing arm that will fit the daytona?

OK, first off I would not recommend fitting a Triumph SSSA on a 675 unless you just ride go kart tracks!!

From memory the OEM SSSA is C to C 490mm, give or take chain adjustment each way, the 675 is 560mm C to C. Again you have chain adjustment so this a ball park measurement.

The 675 has a seriously long swingarm, that's good for suspension tuning everything is more controllable with a longer swingarm. The early 916 had a short arm and would high side at will, this was fixed by extending the arm and it reduced the effect somewhat, made it more controllable. The wheel base was also made longer as a result of the longer arm but it didn't alter the handling on tight twisty track at all.

I have had an S4R swingarm for ages but because it's too long for the OEM SSSA model bikes I've left it sat on the shelf until now. You could also look at 1098 and MV swingarms. They are the same bolt pattern and are interchangeable with each other.

They are the only off the shelf swingarms that's up to the job length wise, the other problem is the swingarm bearings on the S4R, on the Ducati S4R bearings are in the crankcases. So the swingarm will need to be modified to take a needle roller bearing and a ball type bearing to do the job. It can be done though.

Same deal with the shocker, if you are to use the Ducati linkage you will need to fabricate a new mounting boss on the top of the frame.

Pros and cons.

Pros: SSSA bikes look awesome and you would have a unique looking bike, plus the door is open to all the lightweight Ducati parts.

Cons: Not easy to do, costly.
