We’ve been getting all sorts of small requests.
Lately, work hasn’t been progressing as smoothly as I’d like… The bike itself is getting older, so some delays are inevitable, but it feels like the whole schedule has gotten thrown off.
I’ll work through what I can, bit by bit. (‘ω’)ノ
I think I’ve mentioned this before? The Tokico rear calipers from ZRX models work perfectly. 43080-5083-DJ — I was a bit surprised to find that Amazon actually sells genuine OEM parts.

Basically, all GSXR-series rear Tokico calipers are compatible.
• Banjo bolt pitch changed to 1.25
• Bleeder nipple hex size changed to 10mm
• Piston cavity now has a plastic insert
• Changed from external dust seals to internal dust seals, which is standard nowadays
Manufacturers have started wrapping everything in seal tape these days.
I peeled it off.
With a thorough air blow at the end, there won’t be any leaks whatsoever.
Looking at the shape, you can see that fluid residue remains above the taper at the tip, which causes weeping. Fluid residue means rust, so thorough cleaning is essential.
Most parts tend to be standard specifications. There might be some minor spec changes here and there, but without that kind of versatility, part costs would skyrocket.
It’s tricky and there’s a risk of failure, but when you find these kinds of cross-application tricks, it feels like discovering a new shortcut and it’s exciting.
When it’s new, I remove the seal, clean it, and apply MR20 Metal Rubber.
With grease-type lubricants on brake calipers, corrosion seems to progress faster… and the movement feels a bit stiff too.
Let’s check the pistons just to be safe.
The brake pads were borderline on remaining thickness, so I replaced them.
Note that the banjo bolt pitch changes to 1.25, so be careful… I wonder if the manufacturer was trying to create a difference?
For now, we’re at the temporary assembly stage. (‘ω’)ノ
