Buell did not break the mold when it made the 1125CR racing bike. Instead, it washed the mold away—to create a sturdier body.
The frames of other motorcycles are formed by pouring molten metal into a mold of sand and clay. Buell engineers instead developed a water-soluble bonding agent to use in place of clay. The new formulation allows them to start rinsing the mold away right after the aluminum is poured, rather than waiting for the cast to solidify and then breaking the mold. Water cools the alloy faster and in a controlled manner, preventing cavities from forming, which can weaken the structure. Buell used the method to produce a stronger rear frame that requires one less pound of metal.
It’s even possible to cast the entire frame that way, using water cooling to fine-tune the metal’s strength and rigidity for different components.

Beautiful bike, agresive style. But, a 2006 Yamaha R1 makes it bite de the dust. Have a 180Hp and a top speed more than 180mph.
2 out of 41 people found this comment helpfulVery true about the Yamaha, however, he R1 is an entirely different kind of bike. Buell has almost created an entirely new category with the CR. Toss a leg over one and you'll see...

As for material stiffness (modulus of elasticity), cast or wrought are both similar.
The benefit of casting is that the frame section properties and thicknesses can be exactly tailored to meet the design loads. So the frame weight can theoretically be kept low. The drawback of casting is that cast material alloy composition must be compromised, usually with regards to strength, in order to make it castable. So more material must be used to get a strong enough part.
The approach used by most sport bike manufacturers, employing extruded high-strength alloy perimeter spars welded to cast fittings, is actually a very good design compromise.

I have a ZX6R that's 600cc's and tops out at 164 (speedohealer checked)...
not impressed.

Apples & oranges... I also own an '05 636 6R and again, as with the Yamaha comparison above, the ZX6R is in a different bike category altogether...
Also, you're not topping 160 on a stock 636cc bike without a sprocket gearing change...

who cares if other bikes are faster? it looks cool, and i bet its fun to ride

I still fail to grasp why when ANY story comes out about a Buell, the first comment is about how a metric bike is better because it will go faster.
EVERYBODY knows that a metric will beat a Buell on a straight away. These bikes, or any other Buell, is not designed to go fast in a straight line.
If you want to go fast and have the same bike everyone else has... Please, by all means, go get a Jap bike.
We ride Buells because they are fun, and they are far more unique.

Because the whole point of these sport bikes is agility and speed. Their making an 1125cc bike that's slower and less agile than virtually all of its competition and selling it for what? 13,000? The jap bikes are 9k, Daytona too for that matter.
This thing has the price of a Ducati and the performance of the jap models basic 600 classes (not the supersports or literbikes obviously).
Sure they might be fun, but you're wasting money on an under performing bike that isn't up to facing its competition except maybe with vanity.

It's an 08. 599, no 636 though I definitely like the 05's better.
You'll get over 160 just fine without the sprocket on the 08 if you do the jumper mod--I also have a different exhaust but I haven't touched the sprocket yet though I need to since this things bottom end leaves something to be desired.
