I've replace my std MC28 calipers for the CBR ones. I'd highly reccomend it. My original NSR calipers were seized after years of road salt etc. I checking into getting new Honda seals,.....I think the cost came to over £45.

Saw a mint set of CBR ones on eBay for £20, they'd done about 1000miles they were cheaper than a set of new seals, not to mention the hastle of striping, cleaning and re assembling. Whilst I was on the case, I picked up a GSXR radial m/cylinder for £35.

It was a great combination and a cheap way to get almost new brakes. I'd have difficulty holding on, they were that good. Well worth it......for the right price of course.
