The Buell 1125R enters on a road with no return. This is a bike that follows a continuous ascendant trend on the sales charts, looks original and performs as such. Furthermore, Buell even launched a special Superbike racing version to show the great potential laying in the notorious model and we reckon this is only the beginning.

2009 Buell 1125R

Buell Sportbikes take control of the road in 2009, ready to fuel the passion of the most demanding sportbike riders on the road or track.

Buell sportbikes feature an athletic motorcycle riding position, which allows the rider to fully enjoy the handling advantages of the Buell Trilogy of Technology: chassis rigidity, mass centralization, and low unsprung weight. Designed to respond intuitively to rider commands, Buell sportbikes combine real-world street performance with race-proven design. With incomparable styling, the Buell 1125R blends innovative technology with premium components to create an extraordinary riding experience.

The motorcycle that redefines the superbike category the 2009 Buell 1125R is powered by the 1125 cc liquid-cooled 72-degree V-Twin Helicon engine generating 146 crank hp and 82 ft. lbs. of peak torque. With a foundation built on the core Buell Trilogy of Technology creating optimum performance, the 1125R remains true to Buell’s original sense of sportbike style and design.

2009 Buell 1125R

New for 2009 on the 1125R model are targeted fuel injectors, relocated O2 sensors, and updated engine spark and fuel maps. The combination of these features offers improved drivability below 6000 rpm, even crisper throttle response, improved heat management, and significantly improved fuel economy. The updated engine spark and fuel maps will also be made available for 2008 1125R models.

A new gear position readout is added to the digital display on the instrument panel as a scroll-to feature. A high-output alternator has increased capacity for accessory use. Slider bobbins have been added to the swingarm for protection and easy use of a rear stand.

The front wheel rides on fully adjustable Showa 47 mm upside-down forks, while the Buell ZTL2 front brake has an eight-piston caliper. A smooth-shifting six-speed transmission works with a HVA (Hydraulic Vacuum Assist) slipper-action clutch that uses engine vacuum for easy clutch-lever action and reduced engine braking during downshifts.


Given the fact that this is only a two-cylinder engine powering a light, aggressive and very competitive motorcycle, you might tend to believe that, with it, Buell goes against middleweight superbike models such as the high performing Japanese ones, but they’re in fact competing with the very best there is out there. Indeed, motorcycles such as the 2009 Honda CBR1000RR, Yamaha R1, Suzuki GSX-R1000 and Kawasaki ZX-10R now have a faster contender, while the new BMW S1000RR and Aprilia RSV4 European ones are found in the same tricky situations.

Also, Buell recently announced their entry in the AMA American Superbike Class, which proves this fact once again.

2009 Buell 1125R

The 2009 Buell 1125R stands out in the sportbike field with exotic styling and technical innovation, including the performance of a 146-hp, liquid-cooled 72-degree V-Twin engine. Designed from the rider down, each Buell sportbike combines V-Twin power with unmatched precision and agility.

Quiet Zone aerodynamics optimize air flow around the rider for enhanced race performance and rider comfort. The fairing shape was developed using Computational Fluid Dynamics (CFD) analysis, and features six-bulb headlamps, while LED turn signals are integrated into the mirror housings.

The 1125R is restyled for 2009 with new blacked-out chassis components, and is offered in Midnight Black and new Racing Red with Phantom Metallic (Black) wheels, and Arctic White with Hero Blue translucent wheels.

2009 Buell 1125R

Our first meet with the 2009 Buell 1125R was definitely one that started our interest simply because the bike is out of our idea of a superbike or, better said, a “classic” superbike. It does fit the category and even manages to shake things up a little bike. It seems to us that the planets lined up perfectly for this motorcycle and we can’t wait for our test ride.
