I have scoured the web looking for an 09 and newer swingarm for a wide tire conversion. Does anyone have any ideas where I might find one?

 

h. had a tread yesterday on that.you can go to 07-08 swing arms screaming eagle up to 180 mm.or check for tread from ..recycled.. from ontario.i explain whom to modify your..mrfuji

 

I never studied what it would take to adapt an '09 swingarm to an earlier frame in order to get a wider tire mounted but thought about it a bit.
I decided to widen my stock swingarm instead. Read about it here:https://www.hdforums.com/forum/touri...-a-how-to.html
It was a lot cheaper than sourcing another swingarm would be, I think.

Edit: After seeing your signature line, I can see you will be taking a different route than I did. In the thread I linked there is a post by JohnCA58 who went wider and also converted to a chain drive and did an awesome job. He might be a good guy to talk with. Good Luck!

 

I am thinking about the 09 and newer because I need the 25mm rear axle to fit my wheel of choice, a 2004 Ducati 999 17 x 5.5 Marchesini unit with Cush drive.

 

It looks like I can use the 08 standard swingarm, as the Ducati swingarm is 9.424" wide at the axle, while the 08 standard arm is 9 5/8". I will have to have a 25 mm axle made to fit.

My Custom Valley rear fender arrives any day.

 

'02 to '08 swingarms all have an inside measurement of 9 5/8" at the axle so if you get a 1" axle for cheap along with a swingarm, you can turn it down on the lathe to 25mm if you have access to one, then cut the appropriate width spacers that will enable it all to fit. The wheel must be reasonably centered within the frame, the rotor must be centered in the caliper and then you have to ensure you have adequate clearances for the drive pulley or sprocket, depending on what drive system you are going with. Swingarm length will also have to be considered. It can be a balancing act for sure. Post lots of pics, it sounds like an interesting project. Good luck.

 

I am going with a chain final drive, so I will likely have to modify the swingarm to get more axle adjustment. Have a full machine shop at work, so everything should go smoothly ( in theory).

 

I'm not really interested in selling any of these parts but it occurred to me that I have an '07 swingarm, 1" rear axle and 25mm spacer stock all sitting in my shop if you need measurements or pics of anything.
