A masterpiece? The Suzuki OEM caliper support 69721-35F00 has also been discontinued.
If you want to go 220φ with a swingarm torque rod setup, this is it!
The GSX-R750/1100 series comes with oil seals and bushings and other obstructive parts installed.
This one is extremely simple.

To tell you the ideal form… 69721-18G00
Using this and welding a rail to the swingarm side gives you a rigid 220φ setup.
Since the rear is also 28φ, well, that’s completely up to you.
This one will probably be discontinued soon too…..
By the way, the calipers that work are

43080-0040-DJ ¥21,760 (¥19,782) The ZZR1400 has an aluminum piston.

This MOS also seems to have a 94 mm pitch? Still unconfirmed though…
A privilege granted only to the Inazuma… MOS calipers trending?
Repurposing OEM parts is so much fun!
