BellissiMoto's Custom Monster S4RS - The beginning!

[BellissiMoto]

are they casted for forged? i always thought thye were milled.

They offer both what they call forged (but are basically cast), and CNC milled.

Lets just say these were close to free, especially when compared to the cost of CNC monoblocks.

Yeah - the M4 100 that is on the 1098/1198/SF/evo, etc - I call that "cast".   M4 108 is the same thing, but 108 instead of 100

cant wait to see this thing all bolted together . . .

Amazing!  Giving me a couple of ideas with mine!

I know, I can't wait to ride it!

Good news guys,

The tank has arrived at the dealer and is being installed on Saturday.

The new Handlebars have arrived, and the CNC Racing fork collars for the oversize Marzocchi forks should be here early next week.

Still to come:

Carbon Fiber Headlight Surround,

Black anodizing of the chrome headlight ring,

Comp Werkes Exhaust cans,

Carbon Rear Fender,

Carbon Radiator Side Guards,

Carbon Fiber Folding Levers,

Racing Chain,

AEM Factory Magnesium sprocket carrier and sprockets,

Titanium Cush Drives,

and more and more and more...

killin me man.  new rule, no updates without pics!!!!

All motorcycle parts whether they be called "billet," "cast," or "forged" will have machining done to them, there's no other way to get the critical tolerances that are required for moving parts or for motorcycle assemblies other than to machine them. There's really only a few basic ways in which most motorcycle parts can be formed: stamping, extrusion, casting, forged.

I'm not exactly sure how something can be said to be ""forged" but basically be cast". Forging is a process in which metal is repeatedly pressed into shape and results in a much stronger part because the orientation of the molecules is tighter than it would be if it were cast and more irregular with no porosity (or very little). After a part is forged it will need to be machined to achieve the critical geometries. Casting is a process where a metal is heated to it's liquid state and then poured into a mold. This results in small pores within the hardened part and also results in the material hardening with more aligned grain structure, which means it can "crack" more easily. A forged aluminum wheel is lighter than a cast wheel because the material is stronger so the forged wheel can be made with less material than it's cast counterpart.

Parts that are called "billet" such as rear sets, clip-ons, etc, are parts that are CNC machined from solid chunks of metal, usually extruded rods or sheet. Extrusion is a continuous process where a raw metal is pushed through a die creating a new shape, such as a rod or sheet. The effect is similar to forging in that the extruded material will have minimal porosity.

There's two basic types of brakes, mono-blocks and non-mono-blocks or two part brakes. Monoblocks have two forms, those that are forged and then have the critical cavities and geometries machined into them, and those that are machined from solid billet. The latter being more expensive because there's a lot more machining involved. Two part brakes are easiest and cheapest because there's no complicated and time consuming machining to do. You machine the critical tolerances in from one side then bolt these two halves together. This results in a weaker brake structurally though.

Anyway, just figured I'd mention some details about this, even though no one asked

Of course re: machining parts in some fashion!

And Yes, the m4's are called 'forged' - but it is basically the equivalent of having a 1-piece 'casting', with piston holes created later through machining - if you were categorizing it as either "the race stuff" or the current version of the latest "OEM common parts" - it would certainly be the latter.  While these calipers are called "forged", I would be interested to see what type of forging process they are put through, or if this nomenclature is coming from the marketing department.  They are not the billet monoblocks that Brembo makes under the Brembo "Race" or Brembo "HP" line. (Brembo also makes 2-piece billet calipers under the HP and Race lines as well - all rear calipers from Brembo are 2 piece - the OEM, the HP, and the Race lines). 

ISR's calipers are billet monoblocks, and after much petitioning (from ... me), some work is being done on coming up with rear caliper designs (billet monoblocks) for the 3 euro mounts common on Ducati (84mm normal, 64mm "Brembo Race", and 60mm old-world race - for mounts similar to those on the 851/888 race bikes and the Supermono)

[BellissiMoto]

Brembo calls them forged, but if you press them for an answer as to how they are forged, you will find that they are "gravity forgings" which basically means that they found a way to describe the process of pouring the molten metal into the casting mold from a pot a foot above it as some part of a forging process.

The reality is I don't buy into it, but truth be told, it doesn't really matter one bit. I've used these brakes in the past and they perform beautifully, so I have no qualms about using them now.

Though a set of Hard Nickel Plated Beringer Calipers is tempting....

Amen to both - bad ass brakes for sure - especially at the current price they can be purchased brand new - but a bit of a shame that advertising gets in the way imo.    I do wish they came with better pads from the factory on the bikes - something that will eventually wear!  I did something as simple as the EBC HH's in there and thought it an improvement over the brembo pads.   I'm sure something like SRAC's or XRAC's are even more 'brake', but didn't have any handy at the time.

I would love to have some nickel plated calipers, and I hear the Beringer monoblocks aren't too far down the line, but are still currently not available (from my last communications with the N.A. representative - much like how he hinted-at/alluded-to additional 4D applications in the near future)

[Drunken Monkey]

And just to muddy the waters, increasingly you see parts that are "vacuum cast" (or 'vacural vacuum die cast') like the cases on the newer Ducatis.

In theory this gives you the strength of a billet piece with the cost closer to regular casting process.

As usual, Kevin Cameron explains it very well.

And I will add that this thread is, in fact, useless without pics

We had a set of the Beringer hard nickel plated billet calipers in here last week, problem was they were already sold to a customer, and I (for some unknown reason) am starting to feel slightly budget conscious.

If you need a set, we can hook you up with a great price and get them here in probably 2-2.5 weeks.

I've also been pestering Beringer to re-invent the 4D system for use on Radial brake applications for a couple years now and it sounds like we may finally be getting somewhere...
