I’m looking at improving the power & feel of my Buell X1’s front brake set up.

At present it’s all stock and in perfect working order, new fluid, good quality pads etc.

In comparison to the Jap and European bikes I’ve owned in the past there’s a fair bit of effort required and not much feel/feedback from the stock set up.

I initially thought about a twin disc set up but are thinking of shelving that idea for the following:

Replace the stock master cylinder with a Nissin radial, sized to suit the Buell tube framed 6 pot calipers.

Has anyone every replaced their stock MC with a radial set up, and if so what did you replace it with and did you notice any differences.

American Sport Bike have some advertised in their XB section but nothing in the tube framed. They’re supposed to be a direct fit for the early XBs.

Does anyone know whether the American Sport Bike Nissin radial MC for the XB would be a direct fit for the X1 or are the brake switches different.

I don’t need a MC with a mirror perch as I have bar end mirrors.

And lastly……

Has anyone every replaced their OEM stainless steel front brake rotor with a higher friction steel rotor such as the EBC race brake rotor on the American Sport Bike website or something similar, and if so did you notice any differences to the stock setup.

Cheers

I've tried both the Braking wave rotor and now have the EBC rotor fitted. With Lyndall gold pads from American Sport Bike and rebuilt caliper/master cylinder it has better feel and more progression than the stock setup or the wave rotor. Don't waste your money on a new M/C.

+1 on the Lyndalls. It was night and day between them and the EBCs on the stock rotor. I'll spend the extra money on the Lyndalls from now on.

I like the Lyndall Gold pads on my otherwise stock system. Improved feel and it doesn't develop the warped feeling the stock pads do when they glaze up a bit.

I think A.S.B. used to stock a radial mc for the tubers but stopped carrying them due to low demand. It was also a Nissin part.

No idea if the XB part is interchangeable, Al could probably tell you though.

My brakes are decent for my regular commuting, canyon riding and occasional track day. But if I wanted more from them I'd probably attempt to go with a radial mc too (actually I considered it several years ago, but held off). Compared to my XB's stock system my M2 could stand some improvement. sooo actually, if Al is willing to order radial mc's for tubers I'd be interested in getting one too.

I asked Al the following questions:

Is the Nissin 17mm radial master cylinder for sale in your XB section suitable for an 2001 X1 and will the brake light switch plug straight in on an X1? Your site states that you get increased feel and stopping power from the radial MC and this is what I’m after. I’m also considering EBC front race brake rotor for my X1. This steel rotor has a higher friction coefficient. Which is the best mod to do when searching for more feel and better stopping power over the stock X1 set up. Is doing both mods overkill or will it transform the brakes of the X1.

and got the following much appreciated response from Al:

MC should bolt right on, but I haven’t installed one on an X1. Should give a similar feel as the change on the XB since both use the same ½” bore stock MC.

Whatever gain you get from the steel rotor is probably offset by losses from rust impregnation in the pad on a street bike if it is used on the street in rain, etc. And since you shouldn’t use Sintered pads on the steel rotor, but can use sintered with the stainless rotor, you probably have a net LOSS of braking power over a stainless rotor with HH rated sintered pads.

There is a reason why most sport bikes come with stainless instead of steel rotors.

Al

So with the above advice in mind I'm now thinking that the radial MC combined with the Lyndall pads and the stock single disc set up is the best and simplest option to go with as opposed to building a dual disc set up.

Any thoughts or differing views?

I didn't know the part was interchangeable.

Al's a smart guy, I tend to trust his advice on my projects, he's advised me several times and I've always been pleased with the results.

This is probably the least expensive option too, unless you found an extremely cheap front end from another sport bike that you can swap over to get the dual brake set up.

That's just my $.02

Hmmmm. So at two and a quarter I'd need to sell the traction grips I've been hanging on to, and a few other items, to off-set the cost...


...still...


...now you've got me thinking about this again

Here's the part for others who may be following this discussion:

Tuber riders will need to change the plug ends. Just went down to the garage to check, my '07XB has an actual plug where the M2 uses spade type connections.
