Buell motorcycles has released a racing spec version of its 1125R superbike, dubbed the 1125RR. Built specifically for competition in the AMA’s American Superbike class, the 1125RR MSRP is $39,995 – a full 28K more than its stock sibling.

The Buell 1125RR will be available solely to AMA racers competing in the American Superbike series.

The new 1125RR was actually announced by AMA Pro Road Racing first, reporting this morning that the new Buell was eligible for the upcoming American Superbike races at Mid-Ohio. Now the boys from East Troy, Wisconsin have filled in some of the details with a press release of their own.

The biggest changes to the 1125RR are inside its Rotax-built Helicon Twin. The 1125cc engine, sporting an unchanged 103mm bore x 67.5mm stroke, makes use of “a larger airbox and intake manifold, revised valves and camshafts, a higher compression ratio.”

Weight is shaved via new titanium exhaust system and 6-spoke magnesium wheels, which replace aluminum stock units. The cast aluminum swingarm is machined with an axle adjustment system and a chain drive replaces the stock 1125R’s belt system (though the current 1125R is already being campaigned with such a chain drive).

The new 1125RR also sources a modified rotor for its novel ZTL (Zero Torsional Load) front brake. The suspension remains fully adjustable Showa units, front and rear.

The intention of Buell founder and current Chairman, Eric Buell, is clear: “The 1125RR is designed to give privateer racers a turn-key machine to compete in the American Superbike class in AMA Pro Racing. We want to build on our program that has proven so successful for privateers in the Daytona SportBike class.”

Not that the $40K pricetag would encourage many sales, but regular riders will not be getting their mitts on the 1125RR. Only a small amount will be built with Buell PR saying: “Buell will produce a limited number of 1125RR motorcycles for sale only to licensed professional road racers who will compete in the AMA Pro Racing American Superbike class.” Racers will place their orders through the Buell Race Department.

Given the prior controversy regarding the Buell 1125R’s inclusion into the Daytona SportBike class, the creation of a purpose-built American Superbike racer by the American firm comes at a time when riders and fans alike are growing more and more disenchanted with the DMG-controlled series. (For more information of the DMG situation, read Motorcycle USA’s editorial DMG: Delusional Motorsports Group?)

Privateer Taylor Knapp will campaign an 1125RR for his own Taylor Knapp Racing team this weekend at Mid-Ohio.
