Front caliper needs a serious service. I'm after the full seal set (£58 on Wemoto). I realise the caliper is common to a few bikes, will the seal set from a ZX9 be the same?

I also hear they're poor calipers.

Tokico 6 pots (90mm spacing) are often replaced with 4 pot nissins off of a slingshot gsxr and variois other bikes.

Reasons being:
*easier to bleed
*cheaper for seal replacement
*less prone to chew up dust seals, if you rebuild your tokicos the state of the dust seals and seal seats will be in terrible condition
*cheap to buy, so sell your tokicos after to make your cash back
*good braking power

Had a set on my 7r to replace my 6 pots and wouldn't ever go back

As above, look at fitting a set of 4 pot nissins. The 6 pots are poor in comparison.

Give these guys a call and see if they have any refurbed 4 pots in stock.

I have used them before, they know what they are talking about and they are helpful. I got them to refurb the calipers on my ZX7R just because I didn't have the time to do them myself.

Has anyone got any brake test info or measured stopping distances tests for the same bike when fitted with Tokico 6pots and then Nissin 4pot calipers.

I found that if the Tokico calipers are well looked after and bled correctly, then with decent pads they are a very strong front brake. Not as strong as Summitomo monoblocks, but still very good. I've used Nissin 4pots on some Honda's and found them no better at best and sometimes worse than the Tokico's, but this could have been down to pad choice etc.

I don't know, I'm in the same possition my self at the moment, but I won't change the calipers. There is a reason why Kawasaki and others picked those 6 pots. Japs are not stupid, they even used tokico 6 pots in SBK. Rolling Eyes

If new callipers cost the same or more than new set of seals, then I'd keep those six pots where they are. Thumbs Up

I think that it was Performance Bike magazine who modified a GSXR1000K1 or K2 with some 4 pots from a GSXR750 and found them to be lighter and stronger than the OEM calipers.
My brother fitted some Aeroquip hoses and a Brembo master cylinder to his 1000K1 and found a worthwhile differance once he had fitted some better pads.
A TL1000R owning friend had problems with his 6 pot calipers and once we had stripped and cleaned both with new pads,the feel and power was not bettered until the fitting of a Brembo master cylinder.Not sure what pads were fitted though,which can make a massive differance in feel,feedback and braking power.

I fitted some Sumitomo 6 pots to my Exup 1000,replacing the standard 4 pots.The OEM calipers were okay,but there was a clearance problem between the pistons and the caliper body.This caused the pads to drag,causing premature wear and the speed to drop when they got hot.Once I found out that the calipers from the YZF750R bolted straight on,there was no brakes dragging,more power and feel as well as an increase in speed.

I like 6-pot Tokicos. Very good brakes imho Thumbs Up

I had no problems with bleeding them.. a bleeding kit for 6 quid from ebay made it so easy.

They are fantastic brakes when they work, after a full service they are great. The next morning they will be fucked.

Junk them.

No they don't.

Been like that for a while, hence why most of the guys will be using Brembo or Nissin calipers. Thumbs Up

Note radial Brembos. Homologated bike was running Tokico six potters IIRC.

Aye....standard brakes not needed but, interestingly enough, they're introducing a price cap on the brakes for 2014 Very Happy


Can't find detail on the actual price cap. Suffice to say Brembo/Nissin etc. will just make their price whatever the upper limit of cap is. So little will really change.

From what I remember one of the issues with the 6 potters aside from their incredible ability to bind when used in conditions other than hot and dry, was a lack of lever pressure from the OE master cylinder.

Upgrade the master cylinder and that should give you better feel and power.

Instead they'll pay 40,00 euro for a mechanic, whose only job will be to set up brakes. Razz

Aye. there's ways around it no doubt but punishments for breaking homologation regs can be pretty severe I think, and you know what scrutineers are like.
Check the link I added above.


It's the team's job to find loopholes in these things. Competition for you.

And duely noted. It's an extract from the technical regs anyway. Thumbs Up

I haven't read the EVO rules, they should be interesting. I guess they're basically BSB rules.

I was just wondering, are there any callipers that would fit with no mods? Thinking
New seals are about 55 pounds and I think, I could get used calipers for about 65-70 pounds, with some work, of course, it'd be a bit more. My mate's got OEM Nissins on his '98 Fireblade, never touched the seals.

Have to agree with this, had a J1 ZX6R with them on. Didnt change the master cylinder but did service it (this was with braided hoses and new seals all round). Never had a problem with this set up and the brakes were exceptional for my level/needs.

The homologation N model used Nissin 6 pots.....which are awesome....but expensive.

I also stuck 4 pots on any Tokico 6pot fitted bike ive owned.

I still run with the Tokico 6pots on my ZX9. After a rebuild with new HH pads they are awesome.

5 minutes later they need rebuilt again. If you're at a crossroads with the 6pots and the Nissin 4pots - it's a no brainer. Go for the 4 pots. I've sank far too much cash into my 6pots to give up now.
