I had mounted this caliper to my CRF450 some time ago and just loved it. Radial mount, four piston caliper. Way more efficient than a floating caliper. Hung on to the caliper when I sold that bike and finally got around to mounting it to the Showa conventionals I had swapped to my KTM 200. https://www.vitalmx.com/forums/Tech-Help-Race-Shop,42/49mm-Showa-conventionals-conversion,1387998

Mounting the caliper to the Showa conventionals was more complicated then on the CRF. With the CRF all I had to do was whip up a simple bracket and rotor spacer and I was good to go. https://www.vitalmx.com/forums/Tech-Help-Race-Shop,42/Monster-front-brake-set-up,1315296

With the Showa conventionals, despite numerous attempts to fabricate a bracket to bolt to the fork lug, I could just never get the caliper to sit properly. Because of the caliper bracket shape and dimensions, it was always too low or whatever. So eventually I just had to go full ham and modify the lug itself.

This was a little bit out of my comfort zone so I definitely took my time and kept things surgically clean. I machined some lugs to act as receivers for the caliper. Cut the fork lug and then carefully tacked everything into place. I also went with a slightly bigger rotor. Not that the caliper needed any more power, and now it is in complete overkill territory, but so that the caliper is moved a little further away from the center and therefore further away from the spokes. As it is, I had to machine a spacer to move the rotor out from the hub about 6 mm.

The thing is definitely powerful! Definitely a one finger setup. I freaking love this. I think if someone really had their shit together, they would make a smaller 4-piston caliper that would not require spacing out the rotor and then offer it with various brackets to fit the OEM fork lugs. Floating calipers are just so freaking archaic!

Spacer to move the rotor out 6mm.
I use Dykem in excess because it just seems so machinist-like. hahahha
But actually, I have just found that the smaller, more precise and tightly I mark things, the
better my results. I know some people can nail .001" with a felt tip marker, but that ain't me.
I'll take all the help I can get.

Surgically clean, preheat, welded with Zen like focus, build up, shape, finish.

Very happy with how this came out!!!!

Looks factory. What holds the lugs on the lower tubes?

Powerband in every gear !

Thanks!

These lugs are threaded on like normal but don't have the usual set screw. Just lots of Loctite.
Took a lot of heat to get it off! Used red on the re-install.
