You do have all those pics of R&D with different parts etc..... Did you ever get to keep any of those parts? Or buy a few to keep as your standard setup?

Seriously though....after reading the info, I knew what I was getting into and had very low expectations. I've modded other bikes in the past and have also ruined them in the process.

The more I do to the 919......the better it gets.....waaaaay, beyond my expectations.

I think it has more to do with weight reduction.....

Different bars, no pair crap, no mirrors w/crgs, different light weight rotors, single titanium exhaust, chopped tail, no grab bar, sato rear sets...... Am even thinking about a light weight battery & lighter seat pan/foam.....(if only they had some lighter weight wheels)

Take this lighter weight platform, and throw on some good suspension..... I think it will be a better bike than very few have ever experienced on the 919.
It's an excellent platform to build on, as long as your final expectation is consistent with what the core of the build is, and not what it is not. I think the suspension upgrades will be more beneficial than the weight reduction.
What weight reduction will not alleviate is the fact that rear swingarm is unlinked and has a flattish angle. You can tune your way around that to a certain extent but the back of the back will never be able to make work like a linked rear with a decent swing arm angle. I'm happy with mine, still playing with the rear end, front is fine as is (full build).

LDH I have not fitted a Brembo RCS specifically to a 919.

I have installed and used them as replacements on various other bikes with smaller master cylinders and have had no problems whatsoever as long as they were used with 2 caliper - 4 piston set-ups.

They do not work well with single caliper set-ups like on a super-motard where we prefer to use the RCS 15
10-01-2010 01:00 PM
robtharalson A question for LDH: if the Brembo master cylinder is an 18 / 20, which I assume is an expression of the equivalent piston diameter range, is it an acceptable replacement for a 14mm Nissin master fitted to the 919 stock? Have you actually fitted one to a 919, or are you assuming it will work? The reason I ask is in my 30 years of working on motorcycle braking systems one of the most common mistakes is fitting a "trick" master off a sportbike to a system with considerably smaller pistons in the calipers. The hydraulic ratio is so altered it takes a really high lever effort to get the same results as the stock unit, and despite the customer's insistence that since the master is for a high performance system it will improve feel and decrease effort it usually doesn't work out very well. Is there enough adjustability built in to make the Brembo unit work on a 919?

Just asking....

g00gl3it Got my G&J lines put on last night. Man, that sux doing it without a vacuum. First time I've ever done it, too, so that probably didn't help. Finally figured it out, though. Osiris, thanks for your help.

Front brake is TONS better. Can't say so much about the rear, although I'm going to bleed it more tonight just to make sure.

Heading out tomorrow on a Teton/Jackson hole run with Osiris! Anybody near us can meet up somewhere along the 500+ mile route!

Your information is pretty much spot-on here.

For the record unless you custom order the banjo bolts (which we sometimes do) the Spiegler lines come with aluminum fittings, but also re-use the OEM steel banjo bolts with the supplied aluminum crush washers.

Brake lines are pretty much brake lines. I mean in a blind test you wouldn't even be able to tell me if they were Spec -2 versus -3 lines and most riders wouldn't even know OEM lines versus aftermarket if they weren't looking at them with their own eyes. Don't get me wrong aftermarket lines do their job of alleviating the expansion that OEM rubber lines have under harsh use, but few street riders ever truly experience that. Just like with aftermarket air filters that actually harm the performance of the bike, but the owners swear that their new $100 filter is giving them more performance the placebo effect can be a strong manipulator.

Basically what I am saying is that all braided brake lines accomplish the same thing to the same degree of function. I have never had any brand of brake line I have installed on one of my bikes (Galfer, Russell, Goodridge or Spiegler) fail nor have any of the hundreds of lines I have installed on customers bikes ever failed. I have seen them end up looking like crap once the covering on the braided material starts to fade or the anodizing on the fittings fades etc...

The reason I prefer to sell & use the Spieglers is because they hold up better and keep their aesthetic value longer than any other brand I have tried and their swivel fittings means you always get a perfect fit.

AllanB I've a question re the banjos - should alloy concern me at all? I'd have thought stainless would be the preferred metal for the banjo.

I've been on the look and notice the likes of HEL lines only use stainless and are quite anti alloy.

LDH Just use a pair of channel lock pliers on the plastic blocks. Works like a charm with very little effort

They are a bitch to turn tho. I destroyed several of the plastic blocks they provide trying to hold the crimp neck while I rotated the fitting. I finally got it, but sure wish I knew an easier, more effective way. Got any tricks for that one?

Of course, I had it in my vice.

That's another reason why we have started selling Spiegler lines now. Their anodizing process is the best in the industry more more faded aluminum fittings that are so prominent with other brands. I can't ever recall an aluminum fitting actually corroding without something else as a catalyst like using high alkaline cleaners etc

If a new master cylinder and brake lines are more of an improvement than calipers and pads, then I'll go that route. I'm not a racer by any means, but I do have the money and time to make my bike a better ride, and braking, to me, is the most important system, followed by suspension (but I can't afford that one quite, yet, lol).

I do like tactile and precise feedback in brakes; mostly for the accuracy obtained in riding, but also for safety, as I commute a lot.
09-28-2010 10:07 AM
arctic954 Ive installed speigler steel lines on 2 of my bikes..... Have been extremely happy with them. Fit, finish, and installation instructions are always top notch.

Works great with the OEM calipers and brake lines although if you are going to the expense & time to install an performance aftermarket master cylinder it would be in your best interest to have braided lines as well (I sell the Spiegler brand which are all DOT approved & I stock the 919 lines in black with black fittings although some of the members here have bought some custom colored ones for their 919 from me as well)



I recently did some custom ones for myself in purple & white too



I know quite a few trackday riders whose only mods on their bikes are front & rear suspension, rear sets, brake lines & Master Cylinder. That's pretty much the basics of being able to ride quickly.

Suspension keeps the bike compliant and gives you traction with limited tire wear & the brakes slow you down without fade during aggressive use and give you more precision and feedback when trailbraking.

LDH Yes I sell Brembo products. You will have to call or PM me though as I can't advertise or sell them online for the kind of pricing I sell them to Wristtwisters members for.

You'll have to devise a method of mounting up a Reservoir cup, but that isn't to hard. I have actual kits for most sportbikes with clip-ons, but with wide handlebars like the 919 I sell these aluminum bendy brackets to use as mounts.

Here are a few different ways I have mounted them up

Can someone please explain what is it exactly that a radial master cylinder does, to make it different and better as compared to the classic style.
I know zero on this point.
My GSX-R750 has an OEM radial on it, but I can't compare it to the my 919 set up because there is no way of isolating the master cylinder so all I can feel are the overall braking "system" differences.
I have no clue as to how much of the braking differences I feel are from rotor size, caliper design, bike weight, pad material, let alone the master cylinder.

The question is will it "slap" in. Or do you need some special motorcycle mechanic mojo?
