Cool Motorcycles reviews Buell Sport 1125R


Designed for the rider, the Buell® 1125R® model combines performance you would expect in a sportbike – power, precision and agility – with the character, attitude and exotic styling to stand out from the pack. With its V-twin engine architecture, it delivers raw one-of-a-kind sound and performance, offering customers liquid-cooling technology and proven world-class handling in an exciting innovative package.


Buell Intuitive Response Chassis (IRC)

The Buell chassis is the stiffest ever offered by Buell and its rigidity is aided by the engine, which is a stressed member of the frame.

Frame assembly is 10 pounds lighter than previous designs.

5.3-gallon fuel capacity, fuel-in-the-frame

Inside frame construction includes air flow channels for heat dispersion and efficient airflow.

Cast aluminum swingarm has been tuned for stiffness and placed with an optimal pivot point.

The swingarm features slider-bobbins for increased protection and easy use of a rear stand.

47 mm inverted fork tubes are secured in rigid triple clamps to complete the package.

Front Suspension

The fully adjustable 43 mm Showa® inverted fork features a high performance damping cartridge that lets you adjust the setup for any situation. Whether it’s at the track or the ride home, you can optimise the suspension for excellent feedback and razor sharp handling.

Rear Suspension

Fully adjustable, piggyback-style Showa® monoshock lets you fine tune the ride for your weight and riding style.

ZTL-2™ Front Brake


Proven through multiple wins in AMA Pro Racing, the Buell Zero Torsional Load (ZTL-2™) front brake utilizes a 4-pad, 8-piston caliper and single 375 mm rotor. The caliper casting was optimized for clamp stiffness, yielding a more progressive and connected braking feel to the rider. New for 2010, the flycut ZTL-2™ logo adds a trick look to the caliper.

The rim-mounted design eliminates the need for load-bearing spokes or even a second disc, resulting in a front-end assembly that is significantly lighter than competitive designs.

Pirelli® Diablo Corsa III tires feature a three-zone compound for optimum street and track use.

Instrument Cluster with ODIS


Compact yet easy to read, the instrument cluster is next-generation technology for Buell. Featuring ODIS (On-board Diagnostic Information System), it is cradled in a lightweight, magnesium module and features:

Gear position display as a scroll-to function.

Buell® 1125 cc Helicon™ Engine

Development of the Helicon™ engine was driven solely by our desire to achieve the perfect power delivery, regardless of displacement. 1125 cc presented itself as the solution to achieving this. Working with BRP Powertrain GmbH Co. KG, a premier manufacturer of high-performance engines, the result is a lightweight, fast-revving, big-bore, short-stroke engine with broad and seamless power, hitting 146 hp just before the 10,500 rpm redline.

But what makes this engine so addictive is the torque curve. It’s virtually flat, topping out at a stunning 82 ft./lbs. And with only 8 ft./lbs. of variation along the entire powerband, you’ll find that you’re almost always in the right gear.
