It will depend on the year too.

The first 4rt had the same yokes as the later 315 monts. They are all 7/8 bars. They are much thicker where the steering stem comes through the yoke. I have converted these to take fat bars but you need motox clamps and to be handy with a TIG welder and a milling machine.

The later yokes are all fitted with fat bars, and are much thinner in the steering stem area. But to my mind the bars are mounted too far back. These are much easier to convert by using renthal bolt on fatbar clamps, you can move the bars much further forward. You still need to have a TIG Welder and a milling machine.
