Radial front master cylinder

[Agemax]

Looking at converting to a radial front master cylinder on my latest GS project. I could just get a 2nd hand one from a late model sports bike, GSXR/ZX/CBR etc. but thinking of buying new. Cant afford top notch Brembo quality but have found these which look pretty good quality at a reasonable price.

Being an American company i am wondering if any of you guys on here have bought one, or had any dealings with the 2FastMoto company and the quality of the parts they sell?

TIA.

I have seen allot of the 2FASTMOTO stuff around here lately and the item I looked at were made in China. I think they are just importing it and putting their names on it. I could be wrong tho.

** I looked at the manufacture location on the item you posted and it lists Taiwan- which is usually better than China ***

The biggest problem you may have is finding one with the correct bore. Most of the late model sport bike ones are too big to properly match up to your GS brake calipers. You most likely will need a 5/8" bore master cylinder and the late model ones are more like 19-20mm. The one you linked to is a 20mm bore, which is way too big.

Edit - I went back to the link and looked at their other options. They seem to have a fair number with 16mm bores, which will work with the GS brakes.

i am not using stock GS calipers, i have Kawasaki ZX9R forks, with 6 pot calipers. 20mm bore is correct for these calipers.

I have been flirting with that for a while. Yes it's probably (okay definitely) a knock-off. But here's my thinking. A master cylinder is a simple piece of kit to manufacture. I have a massive amount of experience accumulated with Chinese manufacturing of items like this and have never seen one fail.

You are good to go then. I just didn't want you to buy something and then discover it worked like garbage because of the wrong bore size.

got myself a radial front m/c from a 2009 ZX10R, should do the job nicely and much easier for spare parts if needed than an aftermarket item.
