Buell_1190RR.jpgAfter being canned by Harley, Erik Buell is back with the fastest motorcycle he's ever made. The Erik Buell Racing 1190RR develops 185bhp at the rear wheel thanks to a larger, 1190cc version of the rotax v-twin. It's also 8lbs lighter than even the cheater 1125RR thanks to higher quality chassis components. The worst part? This probably would have been a street legal model if Harley didn't have its head so far up its ass.

Update: Dyno comparison between 1125RR and 1190RR below.

Here's what Erik Buell Racing has to say:



The 1190RR is the first new motorcycle from Erik Buell Racing. Based
on the 1125R and 1125RR, the 1190RR brings engine displacement close to
the AMA American Superbike (ASB) class limit for twins and the WSB limit
overall. Although it is not currently approved for AMA ASB class
racing, this bike can be raced in many classes around the world and
should add new excitement racing against other premium street-based twin
roadracers. The 1190RR models are constructed at our shop from new
1125Rs with a complete kit of Superbike level components. Engines are
completely disassembled and blueprinted, with top-shelf internal parts
added to deliver reliable performance at the extreme rev ranges required
for a twin-cylinder bike to compete at these power levels.



The chassis is completely updated with the finest components, as
well as all the details for adjustability and comfort requested by the
top test riders who have been involved over its development. Test riding
of the 1125RR by Alex Barros, Jeremy McWilliams, Chris Ulrich, Taylor
Knapp, Cory West, and more - plus the 1190 motor and a winter of further
engine and CFD development - means we can finally deliver an exotic
American racing motorcycle that will deliver world-class track
performance and excitement for sponsors and fans.
