OV-10A with an OVER frame and air-cooled Ducati engine. There are various other jobs to do, but first we’ll check the campaign disc.

We’d like to upgrade the front, but… it’s really, really big…
Foreign bikes sure are different. Maybe we should machine it… but then again.

We found a box that fits perfectly★ That worked out great!

Out came some crumbly machined material that ignores removal efficiency. It’s got quite the distinctive custom feel to it.

We expected a lot of this stuff to come out, but it appeared pretty quickly… It’s quite a sharp build.
I wonder if the wheel center is okay…

Either way works, but let’s check both to be sure…
We checked the mounting center bore, PCD, offset, number of holes, mounting diameter, disc thickness… and they matched Yamaha and Ducati specs.
