povol.....YOu are not entirely correct. The Harleys they drag race do NOT use a Harley motor.....There is actually very little on it that comes from Harley (if anything at all). All the motors start out as S&S motors. They are then rebuilt from there.

Buell Motorcycle Company officials today announced at Road America they have built a new sportbike, the 1125R, which is powered by a water-cooled engine, a first for the American company.
The 1125R is powered by a fuel-injected, liquid-cooled, 1125cc, 72º V-Twin “Helicon” engine that is built by BRP-Rotax. Bore and stroke is 103 x 67.5mm, compression ratio is 12.3:1 and the engine is fed by dual 61mm down draft throttle bodies.
It is rated at 146 peak horsepower at 9800 rpm and 82 lbs.-ft. of torque @ 8000 rpm and has a redline of 10,500 rpm. The engine is cooled by twin, side-mount radiators and is backed by a six-speed transmission that is equipped with a Hydraulic Vacuum-Assist Slipper-Action Clutch. Final drive will still be via belt, but it will be moved to the left side of the motorcycle.
The new machine has a twin-spar aluminum frame that doubles as the fuel tank but with more capacity than in the past, 5.6 gallons. The fully-adjustable Showa forks measure 47mm, but no rake and trail numbers were released. Showa also supplies the fully-adjustable, piggyback style rear shock, which works without a linkage between the frame and the cast aluminum swingarm. Wheelbase is 54.6 inches, 2.6 inches longer than previous Buell XB models. Dry weight is claimed to be 375 pounds.
The 1125R gets an evolutionary version of the Zero Torsional Load braking system, essentially the eight-piston inverted caliper from the XBRR production racebike. Cast aluminum wheels measure 3.50 x 17.0 inches front and 5.50 x 17.0 inches rear, and the new Buell comes wearing Pirelli Diablo Corsa III sport radials.

NEW BUELL 1125R REDEFINES THE SPORTBIKE RIDING EXPERIENCE
Liquid-Cooled V-Twin Wraps 146-hp in Patented Buell Technology
EAST TROY, Wis. (July 8, 2007) – The Buell Motorcycle Company is set to break the convention of the superbike category with the Buell 1125R, an all-new, liter-class motorcycle that delivers an artful balance of street and track performance. Rooted in the core design principles and character that have defined Buell motorcycles for 25 years, the 1125R offers power, handling and agility that will take its owner to a new level of riding experience. The Buell 1125R joins the XB and Blast as a third and distinct Buell motorcycle platform. The Buell 1125R is expected to arrive in Buell dealerships in late 2007.
"We designed the 1125R from the rider down," said Erik Buell, chairman and chief technical officer at Buell Motorcycle Company. "The 1125R takes Buell to a new level of performance, while continuing to embrace the fundamental Buell principals of motorcycle design and offering a great motorcycle riding experience."
The Buell 1125R riding experience derives not just from its power, but from a carefully considered combination of engine performance, precise-and-agile handling, advanced aerodynamics, and superior rider environment and control, all packaged with distinctive styling that leaves many of the motorcycle's mechanical components exposed.
New V-Twin Muscle
The Buell 1125R Helicon engine is a new 1125cc DOHC V-Twin, the first liquid-cooled engine to power a street-legal Buell motorcycle. This compact, 72-degree engine is the result of a collaboration between Buell and BRP-Rotax, a leader in the development and manufacture of advanced engines for recreational products. The Helicon engine was designed to Buell specifications and is exclusive to Buell. It will be manufactured in Austria by BRP-Rotax. The most-powerful street-legal engine ever offered by Buell, the Helicon engine is rated at 146 crankshaft horsepower, and is designed to deliver optimized usable power, with a broad powerband across its 10500 rpm range. Its V-Twin design retains the styling and character that has always defined the Buell riding experience.
The engine is cradled in a new Buell Intuitive Response Chassis (IRC) with massive, rigid aluminum spars that double as the fuel reservoir. The new 1125R sticks to the three tenants of the Buell Trilogy of Technology – chassis rigidity, low unsprung weight and mass centralization – to deliver race-inspired agility and handling. The all-new front fairing and radiator cowling was developed using the latest computational fluid dynamics (CFD) models to provide superior aerodynamics, rider comfort, and efficient air flow to longitudinal radiators and a ram-air intake system.
The front wheel is supported by 47 mm inverted forks. A new Buell ZTL2 front brake features an eight-piston caliper based on the brake developed for the Buell XBRR racing motorcycle. A smooth-shifting six-speed transmission is mated to a new HVA (Hydraulic Vacuum Assist) Slipper Action clutch that uses engine vacuum to boost clutch-lever action and to provide a "slipper" effect when the engine is down-shifted at speed. A new underslung muffler has dual brushed stainless steel outlets.
The Buell 1125R offers an athletic riding position. Quiet Zone aerodynamics are achieved by managing air flow around the rider for enhanced performance and comfort. The toe levers on both the brake and shift foot controls are adjustable to match rider foot size. The instrument cluster features a large analog tachometer and a digital speedometer, plus an Onboard Diagnostic Information System (O.D.I.S.) screen and other interactive features. The fairing shape is inspired by the Buell XBRR and features six-bulb headlamps. LED turn signals are integrated into the mirror housings.
The Buell 1125R is available with Midnight Black bodywork, Diamond Blue wheels, Diamond Blue frame and swingarm, and Fusion Bronze engine trim.

2008 BUELL LINE FEATURES NEW LIQUID-COOLED 1125R SPORTBIKE
Company Marks 25 Years of Building American Sport Motorcycles
EAST TROY, Wis. (July 8, 2007) – Two major milestones will mark the 2008 model year for the Buell Motorcycle Company. As Buell celebrates its 25th year of building innovative American sport motorcycles, it also makes a significant move into a new category with the introduction of the Buell 1125R, an all-new high-performance sportbike powered by an 1125cc liquid-cooled V-Twin engine.
The Buell 1125R is the first model on an all-new Buell platform, and is one of nine models in a 2008 Buell line-up that also includes five bikes in the Lightning streetfighter series, the original sportfighter XB12R Firebolt, the XB12X Ulysses adventure-sportbike, and the single-cylinder Buell Blast.
"In 1983, I set out to build a world-class American racing motorcycle," said Erik Buell, chairman and chief technical officer at Buell Motorcycle Company. "That project turned out to be the first step on a journey of many exciting twists and turns for the Company and our riders. It's really perfect timing to be able to celebrate a significant anniversary in a year when we launch the Buell 1125R, a motorcycle that applies all of the lessons we've learned over a quarter-century, and rolls out new ideas and innovation. I think the Buell 1125R delivers a combination of performance, intuitive handling and athleticism that will redefine the superbike riding experience."

25 Years of American Sport Motorcycles
To note the 25th anniversary of Erik Buell's founding of the Buell Motorcycle Company in 1983, all 2008 Buell models except the Blast will carry a commemorative badge featuring Erik's signature.
Introducing the Buell 1125R
An all-new model set to break the convention of the superbike category, the Buell 1125R is powered by the Buell 1125R Helicon engine, an 1125cc DOHC liquid-cooled V-Twin cradled in a Buell Intuitive Response Chassis. The Helicon was specified by Buell and designed in partnership with BRP-Rotax, one of the premier recreational engine manufacturers in the world. Utilizing the Buell Trilogy of Tech principles and computer-modeled aerodynamics, the 1125R is designed to deliver the precise handling that has defined Buell for 25 years with a new level of engine performance. Buell developed this powertrain to meet a customer experience specification. It delivers the power of a superbike with the abundant torque characteristics of a V-Twin for outstanding overall performance and tractability. The Buell 1125R is expected to arrive in Buell dealerships in late 2007.
Thunderstorm V-Twin Updates
Buell advances the performance of its air/oil/fan-cooled Thunderstorm V-Twin engine series with a larger crank pin, an improved oiling system, and a new electronic timing system and ECM that controls an all new DDFI 3 fuel injection system. Combined, these changes improve drivability and performance, and reduce service maintenance costs. The Thunderstorm V-Twin engine powers all models in the Buell XB platform.
New Front End on XB12X Ulysses
The XB12X Ulysses adventure sportbike has new off-set 47 mm inverted front forks and robust off-set triple clamps that reduce fork flex under hard braking. Steering sweep is increased from 54 to 74 degrees for improved low-speed off-road maneuverability, and the Ulysses now comes with standard heated hand grips.
