Erik Buell Racing 1190RR: 185hp AMA/WSBK Spec’d

02/26/2010 @ 3:01 pm, by Jensen Beeler22 COMMENTS

Erik Buell Racing has just updated its website, and releasd the first real clear shot of what the EBR 1190RR will look like it in its racing form. With 185hp being made at the rear-wheel (according to the optimistic DynoJet dynamometer), the EBR 1190RR sits at the top of the Buell totem poll. Erik Buell Racing has spec’d the machine to be legal in both the AMA and WSBK, but the 1190RR is not homologated for neither the AMA American Superbike class (yet?), nor for WSBK (even bigger question mark).

Based off the 1125R chassis, the 1190RR is virtually anorexic, dropping 30lbs off the AMA Daytona Superbike racing machine, while still bumping up displacement by 65cc’s. With 93lb•ft of torque on hand at 9,500 RPM, the EBR 1190RR is sure to sling your eye balls into the back of your head…if you can find a racing series to race it in. Full technical specifications after the jump.

  • RT @Asphalt_Rubber: Holy Crap! The EBR 1190RR is 30lbs lighter and 45hp stronger than the EBR 1125R DSB race bike –

  • Oh, yeah… Daddy like.

  • Erik Buell Racing 1190RR: 185hp AMA/WSBK Spec'd

  • Nice! Now. Build one for the street! :-) Otherwise, where will the bike fit into “production based” racing?

  • If one was buit for the road it would have smaller hp specafications .
    like 85 hp and gearring that forest gump made .but veary good idear to make it for the street .Bring back two stroke 1000cc gp with less rider aid .like traction control ect ect.Buell are cool bikes Rotex are aircraft motors less weight more hp.
    300hp + motorcycle is not hypothetical any more..
    there are so many limits factorys have becoues of reliblity..

    If the 1125R looked this good Buell might still be in business!!

  • RT @ducatiparts: Erik Buell Racing 1190RR: 185hp AMA/WSBK Spec'd <– Great news!

  • RT @Asphalt_Rubber: Holy Crap! The EBR 1190RR is 30lbs lighter and 45hp stronger than the EBR 1125R DSB race bike – #motorcycle #buell #ama

  • Agree with MikeD. I really like (liked) Buells, but yeah, I did get tripped up on the looks.

  • meatspin

    i need more views. This Buell actually looks good. The fairing on the other EBR models looked like an afterthought after looking at this profile. Still, no homologation route, so whats the point? I’m sure the AMA will get this in the series somehow, but thats it.

  • Erik Buell Racing 1190RR: 185hp AMA/WSBK Spec'd: Based off the 1125R chassis, the 1190RR shaves 8lbs off the AMA D…

  • “Still, no homologation route…” With Roger E out of AMA racing and logic returning to the series, I’ll betcha they won’t qualify the 1190RR. It’s not a production bike, how could they?

    this bike is spec’d for WSB, not AMA. There is an AMA spec bike available in stock displacement.

    Just in the nick of time, those pesky 600’s are getting away with murder!
