buell.com – There was a time when the sportbike world was defined by a very narrow, very uniform set of rules. Buell ignored all of it with the creation of the Firebolt® XB12R. It redefines what a frame should be, what a front brake should be and what a sporting engine should be. This is a motorcycle for riders who value the light weight and razor sharp agility of a sportbike, but crave the look, sound and feel of an air-cooled, 45-degree V-twin. Its torque-rich powerplant, intuitive handling and proven reliability make it a potent canyon carver. So much for convention.
Buell XB12R Sport Motorcycles
2010 Buell XB12R Features:
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.
6-spoke Cast Aluminum Wheels
The Buell 6-spoke front wheel is extremely light, reducing steering inertia and unsprung weight for better handling on the track or less-than-perfect streets.
Pirelli® Diablo Corsa III Tires
Pirelli® Diablo Corsa III tires feature a three-zone compound for optimum street and track use.
Underslung Exhaust
Exhaust cans are heavy and hot. It doesn’t make sense to hang them up high and off the back of the bike and close to the rider. Our underslung exhaust – a Buell staple since 1985 – concentrates the weight underneath the chassis to provide greater Mass Centralization. The result is a clean, uncluttered look, improved flickability and superior handling. It also features a large-volume muffler tuned to produce a linear horsepower and torque curve.
Buell® Intuitive Response Chassis (IRC)
With its 52-inch wheelbase, the Firebolt® handles with surgical precision. The rigid chassis keeps you stable and confident through the turns, while the 21-degree rake and 3.3-inch trail improves agility.
Frame and Swingarm
Handling is key to everything we do. That’s why our massive frames and swingarms are made of aluminum. Lightweight and extremely rigid, they minimize torsional flex and optimize lateral flex for control in the corners. Incorporating the fuel tank into the frame and the oil reservoir into the swingarm also improves handling. By lowering the placement of the fluids, the center of gravity shifts downward, which explains why a Buell® flicks so effortlessly through corners.
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, with 5.6-inches of travel to soak up every bump and pothole. Whether it’s at the track or the ride home, you can optimize the suspension for excellent feedback and razor-sharp handling
Rear Suspension
A top-shelf Showa® push shock with a fully adjustable damping cartridge allows you to fine-tune the compression, rebound and preload to maximize handling and feedback for any condition.
1203 cc Thunderstorm® Engine
The Thunderstorm® 1203 cc, 45-degree V-twin delivers the iconic look, thunderous sound and power-pulsing feel that only a V-twin engine can offer. Following the style of an American Muscle machine, you can tap into maximum torque in any gear, regardless of where the tach needle is pointing. In fact, you’ll find that over 85 percent of the motor’s torque is available at just 2500 rpm. Performance and dependability are enhanced with a large crank pin, a large-capacity oiling system and an electronic timing system and ECM that control a DDFI 3 fuel injection system. Combined, these features improve drivability and performance while reducing maintenance costs.
Tail Section
The rear section is clean and sleek with a passenger seat hidden under an easily removable cowling.
Immediate Throttle Response Belt Drive
A unique constant-tension pulley eliminates slack in the driveline, resulting in smoother on/off throttle transitions no matter what position the swingarm is in. Clean, quiet and extremely strong, the Goodyear® Hibrex® belt with Flexten® Plus technology never requires adjustments of any kind. It’s extremely light, weighing just 1.06 pounds.
Footpegs
The footpeg placement keeps you in an aggressive riding stance to optimize your ability to quickly shift your weight around the bike while still allowing for a comfortable body position that reduces weight and pressure on your hands.
Convenience Features
Tie-down hooks on the tail section make it easy to secure extra gear.
Battery Tender Plug
New for 2010, a battery tender plug comes standard and is conveniently located underneath the passenger seat for easy access.
12-liter Air Box
The large 12-liter air box is designed to optimize air intake and accommodate a large, easy-to-service air filter.
Handlebars
Clip-on style bars. The riding position helps use your body’s weight to move the bike through turns. Confident and in control, it offers great communication between rider and machine.
Weight
At just 395 pounds dry, the XB12R is extremely lightweight. It feels quick and nimble, and makes cornering transitions effortless.
Fairing
The aerodynamic front fairing provides outstanding rider wind protection while still maintaining a naked exposed view of the 45-degree, V-twin motor.
Windscreen
Tinted windscreens add some style to provide a custom look.
Durability Features
Standard frame pucks help prevent costly repairs.
Low Unsprung Weight
- Zero Torsional Load (ZTL-2™) braking system.
- Mounted to the wheel’s perimeter, the 375 mm rotor with 4-pad, 8-piston caliper transfers braking forces directly to the rim instead of through the spokes.
- Front-end weighs approximately 7 pounds less than most dual disc set-ups, which significantly reduces unsprung weight.
- Buell Immediate Throttle Response™ system with innovative idler pulley.
- The XB product line has the same Goodyear® Hibrex® final drive belt with Flexten® Plus technology that was developed for the 1125R®.
- Benefits include improved wear and debris resistance, not to mention the fact that it weighs three or four pounds less than chains.
- Clean, quiet, lightweight, no lubrication, no regular maintenance, and no scheduled replacement.
- No adjustments and no driveline lash.
Performance and Handling
- The same AMA Pro Racing winning 4-pad, 8-piston ZTL-2™ (Zero Torsional Load) front braking system that stops the 1125R® also adorns the Firebolt®.
- The same premium three-zone Pirelli® Diablo Corsa III tires that adorn the 1125R® are standard on the XB12R for optimum performance on the street and at a track day.

Ergonomics/Seating Position
When tucked in during aggressive riding, ergonomic cut-outs help connect the rider with the machine and offer better feedback.
O2 Sensor in Front Header
A second O2 sensor has been added to the front header with an updated engine calibration, improving both fuel economy and drivability.
Usable Power
1203 cc models redline at 7100 rpm and 984 cc models redline at 7500 rpm. The power is right there when you need it. So you won’t have to wait for the engine to rev up to the powerband.
Cam-driven High Output Oil Pump Gear
Derived from race testing, this track-proven component improves internal oiling for the crankpin and bearings, increasing service life for all dynamic systems of the powertrain.
Enhanced Air Cooling
As soon as you turn off a motorcycle, the hot oil begins to break down, potentially leading to engine damage. But on a Buell®, the temperature-controlled fan continues to cool the oil even after you pull the key. The fan also has you covered if you happen to get stuck in traffic.
Thunderstorm® – DDFI 3
Actively controls and monitors the Throttle Position Sensor (TPS), Idle Air Control (IAC) and spark timing, automatically zeroing the TPS and adjusting fuel metering at idle and throughout the driving range of the engine to provide a smoother idle and reduced maintenance.
Thunderstorm® – Automated Timing
Electronic engine management system actively monitors and adjusts fuel mapping and timing to current riding conditions for improved ride quality and superior service life.
Large Crank Pin and Bearings
Enhances durability over the service life of the vehicle.
Uniplanar™ Isolation Mounting System
Using two rubber isolators to minimize vibration transfer from the engine to the rider and three tie-bars to inhibit lateral movement between the engine and the frame, the Uniplanar™ Isolation Mounting System decreases rider fatigue while contributing to chassis torsional rigidity for improved handling.
