Why not buy it from them since they answered your question?
Woohoohoohoo! Two personal records! For breath holding and number of sharks shot in the face.

Very good question... Maybe, they don't sell direct?
Well I got my hands on both masters from a 749, got em for $150.00[both], now I need to get the levers... No hurry here, first, need front suspension...

Spiegler USA certainly sells direct.

You said it... Spiegler USA
At times, European companies, don't sell direct to customers, they prefer to do it via 'distribuitors' or 'authorized resellers'... Just ask Rizoma, they wont sell direct.

I'm confused, they may ship international...

Think he's in Portugal... For Germany and German companies, that's not international any more...

The ISR master cylinder is the best I've ever used... I like it better than the billet radials from Brembo!

My current setup.

Switches integrated into clutch...


Brake master...


Rider's view (I took the second switch button out since I wasn't using it)...


And a shot of the mono bloc calipers for good measure...

It's above the two buttons. That's also how the power to the bike is turned on. No key or anything else.

I've never quite understood the need for a billet or aftermarket clutch MC.  Anthony, does it make a difference on the track?  Cuz while I'm sure it helps with clutch feel, but I've never been a good enough rider to need such precise clutch control (other than during race starts, which I suck at).  

BTW, aren't those 6 pistons overkill on a 675?
Occasionally AFM #702  My stuff:  The M1000SS, a mashed r6, Vino 125, the Blonde, some rugrats, yuppie cage, child molester van, bourbon.

The clutch is just a cable clutch perch with adjustable lever (about $160 so it's not like buying a hydraulic duc lever). This thing is 10x as precise as the original cable clutch so it does help in the fact that there is no sloppy clutch work, but it doesn't make me any faster. The brake is a different story though!

For Ducati the ISR hydraulic clutch it does help incredibly as it reduces the pull by 25% or more depending where you adjust the leverage point (that is on the 14mm version). To me that is a big help... and if you subtract the price of a slave cylinder and adjustable lever you are paying very little for a billet master cylinder that is tremendously more precise and adjustable than the stock setup.

The 6 piston calipers are over a pound lighter than stock ON EACH SIDE! That is a huge loss of unsprung mass. The stopping power is outrageous as well (which is what I like). The stock setup from Triumph is weak in my opinion.

So are these things necessary? No... but I do enjoy them as they make me more comfortable when I ride and when I'm comfortable I'm smooth and when I'm smooth I'm fast (relatively speaking).

1 1b each side of unsprung weight?  Holy crap!  I was asking more about the need for 6 piston v. a 4 piston set-up, but that weight loss is just awesome. 

Interesting pt re the billet clutch master for a Duc's hydraulic system and the associated cost.  I never thought of it as a substitute for a slave cylinder and adjustable lever, but that's a good way of looking at it (and justifying adding more bling.   ;D) 

BTW, this is OT, but I love the 1098R build.   [thumbsup]

Hi Folks,

Yes, in Europe almost each country have a representative.
Only a few sell direct parts to final customer.

I get the MC, is the 20mm  [thumbsup]


Now, I will need some time to mount it in my M696 pjfa Edition  [coffee]

@ Desmoworks - nice piece of Art, a real sculpture you've got there  [thumbsup]
