BUELL MOTORCYCLE 1125CR


Introducing the new power-to-weight class leader, the Buell 1125CR. A fearsome blend of superbike performance, sinister styling and wicked attitude, it pushes the boundaries of the naked category. This 21st century, café racer combines a featherweight chassis with a dominating 1125cc liquid-cooled, V-Twin for powerful acceleration in any gear. Add to that its aggressive, sport riding position and precise handling and you’ve got an experience like no other.

Power
1125 Helicon Engine

A Buell exclusive, the powerful Buell Helicon® 1125cc, 72-degree, liquid-cooled, V-Twin engine.
1125cc

Most powerful Buell street engine to date. By not compromising to conform with a race class spec, 1125cc’s gives this engine the right bore and stroke combination to deliver superbike power: 146 Hp. and 82 ft/lbs of torque, with a redline of 10,500 RPM. The broad powerband and seamless torque curve generates hard and fast acceleration from anywhere on the RPM range.
72 degree V-Twin

The look, sound, and feel of a V-Twin engine deliver the character and superior ride experience you expect on a Buell. The 72-degree V-angle creates a compact, efficiently packaged engine and allows additional weight to be distributed to the front of the bike. It also allows for inclusion of an optimum downdraft fuel intake system, thereby lowering the height of the center of gravity as well.
103.3 mm Bore & 67.5 mm Stroke low inertia flywheel

A big bore, short stroke and light flywheel deliver complete power and quick-revving performance.
Finger-Follower Valve Lifters

The Buell Helicon motor's valves are actuated with finger followers and adjusted with shims. Derived from F-1 race technology, finger follower valve actuation reduces friction and permits a quicker valve opening due to reduced weight. Shim replacement is quick and easy due to the unique follower retention system.
Closed loop fuel injection system, DDFI3 EFI 61mm dual throttle bodies

Immediate throttle response in any environment is delivered by the Helicon motor’s closed loop FI system. It provides constant feedback to the ECU based on environment and ensures an efficient mixture control system, resulting in smoother throttle operation and better fuel economy. The 61mm dual throttle bodies allow for superior air intake and optimum engine performance.
Dual Overhead cams with self adjusting chain drive; 4 Valves

The single-cam-per-cylinder chain drive contributes to the engine’s compact design. The intake cam drive is driven by the chain while the exhaust cam is gear driven. It requires less space over the cylinder head than a three-sprocket design, reduces weight and allows the engine to be located in an optimum, forward position.
Magnesium Valve Covers

Durable and lightweight, the magnesium valve covers are another example of how Buell is able to keep the overall weight of the motorcycle extremely low.
Primary balancing with three internal shafts

The dry sump improves power by increasing efficiency, while the integrated oil reservoir at the lower left side of engine keeps the engine compact and fluids low, contributing to mass centralization.
Twin Side-Mounted Radiator Cowlings

Twin radiators are mounted longitudinally within aerodynamic cowlings. The position of the radiator system allows the engine to be positioned forward in the chassis, creating a more optimal weight distribution from front to rear. In addition, the position of the cowlings captures free-flowing air, driving airflow into the cowlings (and away from the rider), directing the air for more efficient engine cooling.
Dry Sump Oiling with integrated oil reservoir located in the lower crankcase

The dry sump improves power by increasing efficiency, while the integrated oil reservoir at the lower left side of engine keeps engine compact and fluids low, contributing to mass centralization.
Compensated Front Sprocket

By placing the compensation function in the transmission output sprocket rather than the wheel sprocket, unsprung weight is reduced, helping to improve handling.
Camshafts

The single-cam-per-cylinder chain-drive contributes to the engine’s compact design. The intake cam drive is driven by the chain while the exhaust cam is gear-driven. It requires less space over the cylinder head than a three-sprocket design, reduces weight and allows the engine to be located further forward.
6-Speed, close-ratio transmission

With lowered final-drive gearing for hard acceleration, the six-speed, close-ratio transmission provides the rider the right gear on any ride and any situation.
Oblique stacked transmission configuration

The Helicon powertrain stacks the primary and secondary drives to yield a more compact overall design. This increases front weight distribution to aid in anti-squat and improve suspension response. It also allows Buell engineers to design a forward placement of swing arm pivot, providing room for a longer swing arm and better overall handling.
Hydraulic Vacuum Assist (HVA) slipper -action clutch

The smooth clutch lever effort and slipper-like action mechanism reduces engine braking during hard deceleration and enhances the overall rider experience.
A 12 Liter Air box

The large, 12-liter airbox is designed to optimize air intake and accommodate a large, easy-to-service air filter.
Ram Air System

Using computational fluid dynamics to optimize the air flow, the RAM air system pressurizes the air box for a performance gain at speeds over 80 mph.
