Ok, I love my 48 but just couldn't get past the 150 rear tire. After a lot of measuring and investigating I came up with a combo that works. 2013 dyna fat bob rear wheel and a 180/55/17 Scorcher 11 tire, you'll also need a rim band and a tube. At this moment I have it all mocked up and aside from some minor trimming on "through fender" bolts everything seems to be fitting very well.
Stock wheel is 16x3.5 and the dyna wheel is 17x4.5 however both hubs are the same. Stock rear tire "in use" dimensions are 6.5 wide and 26.06 diameter and the new tire is 7.48 wide and 25.35 diameter. Although the stock rear is a Scorcher 31 and the 180 diameter would have been much closer I chose the Scorcher 11 180 because it was a touch narrower then the 31.
If I can help anyone with part number, measurements etc.. Just let me know

 

Very cool bro, nice work, need some side view pics!

 

nice! no mods to the belt or pullies?

 

Side view pics coming soon. So far with the mock up I've done the pulley and belt clear, there was .75 Clearance between the 150 tire and the belt. The 180 is an inch wider then the 150 ( .50 per side) which leave .25 between the belt and tire

 

Looking forward to the finished product....

 

Hi
Looking good. This is exactly what I want to do on my 48.
Would greatly appreciate your letting us have all details part numbers etc. Really looking forward to seeing pics of the final build. If its easier for you you can send me private MSG on here or I can let you have my email address.
Cheers

 

Awesome. Stoked for the finished product.

 

I as well am interested in the part numbers, the only hold back I have had with doing something like this is an earlier post that siad you must change from belt to chain and I didn't want to do that..

 

That looks killer and can't wait to see it all done.

 

So your saying with this tyre the stock swing arms fine, the inside of the fender arms are ok and don't need trimming, and both brake and drive belt line up? Do you have pics of the drive belt side?
Cheers
