XBRR motor??

[Kid1620]

Anyone know where I might be able to find one and how one would cost??

Saw an rr go on ebay for over 13000. That was the whole bike though.

I remember seeing someone selling one on one of the other forums. I believe it was just the engine and can't remember which forum it was

This is in one of my buell catalogues.

Wow $18,000 looks like that's out of the question lol. Would be ridiculous to have that on the street o well on to the next idea.

forgive me but I'm not familiar with the engine, is it the same architecture as an xb engine? info?

I dont think that motor would last very long on the street. The "pork chop" flywheel would rattle every filling out of your teeth at a stop light. The motors didnt have a very good survival rate at the track even. But one good thing that came out of that motor program was the updated oil pump that the 08+ bikes got a similar version of.

It's the race motor with bigger and lighter valve. Stronger push rods, special built crack, cams, head, connecting rods and pistons. Has 150hp, dual throttle bodies, down draft injection with the injectors as close to the intake valve as possible. Basically it's the badest motor you could put on an XB.

wow 150hp out of a sportster casing? That's impressive...

Back in the day, the claim was that the XBRR motor used melted sportster cases poured into different molds.
