EBR 1190 engine info -- squashing some misinformation out there

[Ed / AF1 Racing]

From EBR:

We call the 1190 engine an “ET-V2,” which stands for, “East Troy V-Twin.” It is not a Rotax. EBR purchased the rights for the 1125R engine from Rotax and the engine has been significantly developed beyond the original design. EBR’s proprietary Controlled Swirl Induction (CSI) is an example of a major change that produces major results. Beyond that, pistons, rods, cylinder heads, cams,
cooling system ,virtually everything has been changed from the 1125 design. Components are sourced from around the world, but the engine, like all EBR motorcycles, is completely assembled at EBR’s manufacturing facility in East Troy, Wisconsin. Rotax does not make a single part in the engine.

EBR took an 1125 cc, 135 hp Rotax engine and turned it into an 1190 cc 185 hp EBR engine.

How do you get a 37% increase in power with a 6% increase in displacement? Answer: You completely re-design the engine to make it your own.

It may look like the old Rotax engine, but it's obviously something very different.
