Ninja front brake caliper

[andym]

Just a quick (probably dumb) question....

Will the front brake caliper from a C1/C2 fit on an E1/E2 ZX9R? Looking on ebay and there is loads listed for the C1/C2 model and apart from the colour they look exactly the same.

I think I may have scratched a piston when I was replacing the seals as the front brake lever will come back almost to the grip when the bike has been left, pull the lever a few times and the brakes firm up..... for about 10 seconds then the lever feels soft again.

They take the same brake pads according to wemoto. If the dimensions of the caliper look the same and the bolt-holes look in the right place, I'd go go for it.

What about rebuilding your calipers with new pistons?

Yes, it's the same 6 pot caliper. I'd go with Nissin 4 pots, but I am biased. Less cleaning/rebuilding, more riding.

Also the pistons are around £25 each for the large and about £20 for the small but a second hand caliper is between £30-£75

The same Tokico 6 pots were also used on other Kawasaki and Suzuki motorcycles from that time period. ZX-R, ZRX, GSX-R, Bandit, TL/R...

I've never gotten my set of Tokico 6 pots to work, after 3 cleanings and one rebuild I just sold the bastards for about £30. I lost the front brake in front of a corner and then mid-corner the pots wouldn't just retrieve back into the calipers, so the brake was binding, nah, feck it I said and sold the 6 pots the very next day. I got a nice set of Nissin 4 pots for about £35 with alright pads. It was a direct swap. I cleaned them only once, never had a problem ever since. The bleeding is also nice and quick.

I don't want to rant the Tokico 6 pots here, I might have been just unlucky.

Many motorcycles had those Nissin 4 pots (Tokico 4 pots would also fit, but those are quite rare, used mostly on TL and GSXR 600/750/1000 SRAD later on, instead of the Tokico 6 pots). The Nissin 4 pots were used on Suzuki motorcycles, my set came from a RF900, but you can find them on GSXR 750/1100, Bandits, and other motorcycles, even on Triumphs (if you don't mind the Triumph branding on them)...

90mm between the bolts that hold the caliper on the fork is pretty much all that matters.

NOTE I: Although Yamaha blue spot calipers seem to be like a great fit, they are not, those are 100mm between the bolts. In other words, the only motorcycles you're gonna find the Nissin 4 pots on are made by Suzuki (and Triumph). Honda, Kawasaki and Yamaha never used them. There are also Nissin 6 pot calipers, which are supposed to be the top notch stuff, but I never got a pair around.

NOTE II: Keep the bolts from the Tokico 6 pots. If you get the Nissin 4 pots from a GSXR for instance, the Suzuki bolts might be short (my were). The bolts that hold the hoses in the calipers are also not the same as those you have on your Kawasaki. Use the bolts that come with the calipers, the thread is different.

NOTE III: Just type ''Nissin 4 pot'' into ebay/google or where ever you buy stuff from. Some people even sell them as a replacement for the Tokico 6 pots.

The difference between Tokico and Nissin 4 pot calipers (both are a perfect fit):

Having just rebuilt a set of tokico 6 pots, I'd also say replace. The were a bastard to bleed!

I've got tokico 4 pots and they're lovely

What's the caliper mount spacing on yours?

Just a quick update to this, I found a caliper on ebay for just over £50, it arrived a couple of days ago and I got round to fitting it this morning (even though if things had gone tits up I'd have been walking to work), anyway I had 45 minutes to clean it, fit it and bleed the system.

25 minutes later the job was finished, the brake lever was definitely much firmer and stayed that way. The brakes have definitely improved a lot and I imagine if I tried hard enough then I could do a stoppie or go over the handlebars, they just don't seem as sharp as my other bikes
