2009 1125R Overview

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.

New for 2009 on the 1125R and 1125CR models 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.

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. Production of the 2009 1125R is scheduled to begin in late September 2008.

2009 1125CR Overview

Naked styling and clubman-style handlebar give a respectful nod to the nostalgic era of café racers. A 146-hp liquid-cooled V-Twin engine is geared for acceleration. Sinister styling.

Sophisticated technology. The 1125CR, Erik Buell’s 21st century interpretation of the classic café racer, is a new motorcycle that defies convention and expands the streetfigher category in the direction of superbike performance.

Positioned behind the black-anodized, tapered aluminum clubman-style handlebar and streamlined headlight and flyscreen, the rider has a wide-open view forward that intensifies the sensation of speed. With a dry weight of 375 pounds, the 1125CR is the lightest liter-class streetfighter on the market, and combined with 146 horsepower, it offers the best weight-to-horsepower ratio in the category.

The Buell 1125CR offers liquid-cooled technology and responsive handling from a proven platform based on the Buell Trilogy of Tech principles. The Buell Helicon 1125 powertrain provides the foundation for this riding experience. This 1125cc DOHC V-Twin engine features a compact, 72-degree design and is rated at 146 crankshaft horsepower and 82 ft. lbs. of peak torque. Buell DDFI3 closed-loop EFI produces throttle operation with a quick, smooth response.

New for 2009 on the 1125R and 1125CR models are targeted fuel injectors, relocated O2 sensors, and updated engine spark and fuel maps. The combination of these features offers improved drivability below 6000rpm, 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 ram-air system pressurizes the 12-liter air box for a gain in peak performance. Twin side mounted radiators within aerodynamic cowlings lower the center of gravity (cg) and centralize mass. The exhaust system features an underslung muffler mounted below the engine to optimize cg location and mass centralization. An HVA (Hydraulic Vacuum Assist) Slipper Action clutch features hydraulic actuation from the hand control with assistance from engine vacuum for lighter clutch effort and reduced engine braking. Low 76/27 (2.815:1) final-drive gearing produces outstanding acceleration.

The engine is rigid-mounted as a structural component of the Buell Intuitive Response Chassis (IRC) that has outstanding torsional stiffness, yet is compliant in the planes required to help absorb mid-corner bumps, and doubles as a 5.3-gallon fuel reservoir. Showa 47 mm inverted forks and a Showa rear shock absorber are both fully adjustable. Positive braking performance is provided by the Buell ZTL2 front brake system. The rear brake caliper is mounted directly to the inner surface of the swing arm and weighs 1.5 pounds less than a typical rear-brake design.

All this performance is packaged in a motorcycle that is visually stunning. A narrow headlight pod incorporates a clipped flyscreen, while a removable cowl covers the passenger seat section. The blacked-out frame and chassis components contrast with red highlights on the front brake caliper, wheel rims, rear shock spring and damping adjusters atop the fork tubes. The Buell 1125CR will be offered with Racing Red or Midnight Black bodywork. Production of the 2009 1125CR is scheduled to begin in August 2008.
