GSXR Master Cylinder - need confirmation please

[dr_erni]

Hi all,

I just picked up some 06/07 GSXR 600 front calipers and a master cylinder from the same bike... however looking at it, something doesn't quite seem right.

- I see a 3/4 stamp on the bottom
- Looks like the banjo bolt is on the bottom side of the cylinder

Pictures of the M/C are below, could someone please confirm this is the right one?

What you have shown in the pictures is indeed a 3/4" (19.05 mm) radial master cylinder that comes stock on many newer model japanese sportbikes, including the 06/07 GSXR 600. The banjo bolt is on the bottom of the master cylinder on all radial master cylinders as far as I know. I just put one from an 06 GSXR 750 on my Sprint ST to replace the 14 mm master cylinder.

Thanks wizz-o!

I just wanted to make sure, because threads I read mentioned a 5/8 MC. So, I guess this one would be... firmer?

Either way, sounds like the MC above should be fine to use?

Here is that GSXR M/C on my TL - I have the same one on my Triumph, just this image is clearer than anything I have for the Daytona.
Radial master has the piston/cylinder perpendicular to the bar, whereas the conventional M/C is parallel to the bar.
Note that you will need new lever for it also.
And ideally get the res bracket from the later S3 Part # T2021004

I really appreciate the help SO glad this was the right part! I picked up the matching Tokico calipers as well. As for the levers, I'll see if I can get a matching set (GSXR brake / Triumph clutch) from a supplier.


Also wondering about new lines. Did you guys make your own, order a custom set or used existing ones from another model?

I'm going down this road too. I have everything I need now (apart from time!) - new calipers, levers, master cylinder, hose, reservoir, bolts etc. etc.

I'm following the gospel according to Bohdan, see the chapter and verse here:

I was going to document my progress in a dedicated thread. I'd be happy to compare notes, or answer any questions you might have.

Cheers!

That's awesome! I'm just assembling the parts right now. We'll definitely compare notes come install time!

Where did you get your lines from and how long are they with which fittings?

Actually have an opportunity to grab a set of 04-ish R1 Monoblocks... Would anyone know if those would be a better choice then the Tokicos???

I have Galfer lines, got them through Cycle Brakes - I'll look for spec on them tomorrow on the lengths

This is what the GSXR guys used to use as an upgrade. So probably yes.

But the Tokicos are also many steps better than the 1050 Nissins, so either brand will be a big upgrade on a Triumph. I had the (GSXR1000 2005) Tokicos on my old 1050 and was very happy with the performance.

I have the Tokicos and they perform well
The Monobloks are lighter & probably better looking
You need some spacers with them though ..........
