New Buell Engine?
Some foreign guys have been coming into my work alot lately and last night we talked to one of the guys. He said he was from Austria. He said him and the other guys designed a new liquid cooled engine for Buell and they were here implementing it and making sure everything goes okay. Could have been talking about the 1125R but that has been out for a bit. So maybe they are rolling out another one. Anyone heard anything?

The 1125R has been out for a while. It does feature an Aprillia motor. I would guess they are working on something completely new, since the 1125R has been out for a while.
Whether or not it's a liquid cooled motor is still up in the air.

I figured it was something new, just curious if anyone heard anything. He did say it was liquid cooled though. He made it seem like it wasn't going so smooth though.

RE: New Buell Engine?
Rotax builds none of their own engines. They assemble Buell and many other manufactures engines. The 1125R is a proprietary engine, exclusive to Buell and designed by Harley engineers at the PDC inMilwaukee. It features a 72 degree v-twin that produces 146 horsepower an 82 pounds foot of torque and revs to 10,500 rpm. Bore x stroke is 4.055"x2.658" or 68.7 cubic inches with 12.3:1 compression. It has liquid cooled cylinder heads only (09 baggers ?). DOHC 4 valve per cylinder, dual 61mm throttle bodies usinga similarflawless DDFI used on the XB's. The clutch has a unique vacuum assisted, slipper action clutch. Very cool. First one rolled out of KC 30 Oct 07.

The Liquid-cooled 1125cc HeliconÂŽ V-Twin developed by BRP/Rotax is based on the same technology used my Aprilia motors. It may be proprietary to Buell, but it started with the same technology as the ones used by Aprilia.
