E-series rear caliper piston size

Post by Duper80 »

Hi guys, I recently disassembled my rear caliper to clean and rebuild it but somehow lost the caliper piston :doh:, does anyone know for sure if/what other bikes use the same rear piston? Or know the dimensions of it? The oem piston is like $80-$85 canadian with shipping so I'd like to find an aftermarket option, I'm thinking it's around 25mm diameter and 25mm-30mm long?

I think I would just buy a used caliper or check on the price. I know CA dollars don't go as far on dirt bike parts, though.

I've already cleaned and rebuilt my caliper so it's ready to go back on just need the piston, if I have to I'll bite the $80 bullet and buy the oem piston but it would be awesome if I could find another bike that uses the same piston so I can buy an aftermarket piston for $20-$30

Yeah that's where I buy most of my oem parts, I'm just trying to avoid paying $80 for just a caliper piston so I'm hoping someone can help with the exact dimensions/size of the piston so I can check if another bike uses the same one, but after doing so much research I'm almost positive it's an e-series specific part because it's not showing up in any of my cross reference searches :hmm:

Yeah, I saw one on eBay that said it was for RM and 1995+ KDX. Sorry to not be of more help. Maybe you will find yours.
