1125R
Sports Performance
Like a coiled spring, it goads you to let it unleash its full torque and power, yet give it the command and it will come to a perfectly controlled and disciplined stop. Developed with input from some of the world's best and most experienced professional racers, this bike has really been put through its paces and is already making its mark in race series around the globe. It's fitted with 47mm Showa® inverted forks, QuietZone™ aerodynamics and the impressive ZTL2™ braking system. And while the liquid-cooled Helicon™ engine churns out up to 146hp, the intuitive response chassis and race-inspired geometry put you firmly in control whatever you're competing with.

Buell Intuitive Response Chassis (IRC)
The Intuitive Response Chassis (IRC) is the stiffest we've ever built, resulting in a bike that's better able to hold a line with minimal flexing or bending. Constructed of lightweight aluminium, it responds with precision and predictability during aggressive riding, delivering an unprecedented amount of feedback, regardless of road conditions.
Frame and swingarm
The cast-aluminium swing arm has been specifically designed for improved rear suspension geometry while its stiffness has been tuned for the 1125R™. Its pivot shaft is carried in the engine cases to create a stiff connection between the rear wheel and the rest of the chassis.
Fuel Capacity
With 20.1 Litres of fuel positioned in the frame and as near to the centre of mass as possible, the rider is able to spend more time on the road enjoying the 1125R™'s precision handling and less time at the fuel pump.
Front brake
Buell Zero Torsional Load (ZTL²) front brake utilises a four pad, eight piston caliper inspired by the XBRR race motorcycle. A single 375mm rotor mounts directly to the rim producing outstanding stopping power. The caliper casting was optimised for torsional stiffness, yielding a more progressive and connected braking feel to the rider.
Front suspension
TTo match the stiffness of the main chassis, the 1125R™ uses a fully adjustable 47mm Showa® inverted fork, contributing to superior feel and greater feedback. Spring rates and damping are optimised for agility and responsiveness.
Exhaust
Exhausts are heavy. It doesn't make sense to hang them up high and off the back of the bike. Our underslung exhaust concentrates the weight underneath the chassis for Mass Centralisation and it's been a Buell staple since 1985. The result is a clean, uncluttered look and improved flickability and superior handling. The 1125R™ exhaust system features a large-volume muffler tuned to produce a linear horsepower and torque curve.
Rear suspension
Fully adjustable, piggyback-style Showa® monoshock lets you fine tune the ride for your weight and riding style. Linklessly mounted to a pivot point placed forward on the engine case, it enhances rigidity while reducing squat during hard acceleration.
Tyres
Pirelli® Diablo® Corsa III feature a three zone compound for optimum street and track use.
Rear Brake
The rear brakes utilise a two-piston caliper and a 240mm stainless steel rotor. The caliper is mounted directly to the inner surface of the swing arm - hidden from view and weights 0.7kg less than a typical carrier-equipped rear caliper system - reducing unsprung weight and complexity.
Steel Braided Brake Lines
Both rear and front brakes are fitted with steel braided brake lines for a better correlation of lever pressure to brake pressure resulting in improved brake feel.
6 spoke Cast Aluminium Wheels
With braking forces distributed through the entire rim due to the ZTL perimeter mounted brake rotor, the Buell 6-spoke front wheel can be made extremely light, which reduces steering inertia and unsprung weight for better handling on the racetrack or the less-than-perfect streets you'll ride everyday.
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 Veyance® Hibrex® belt with Flexten® Plus technology never requires adjustments of any kind and weighs just 0.5kg compared to drive chains, which weigh 1.8-2.3kg.
1125 Helicon Engine
Powerful Buell Helicon™ 1125cc, 72-degree, liquid-cooled, V-Twin engine. The Helicon engine is exclusive to Buell.
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 its superbike power: 146 Hp. & 111Nm (82 ft.lbs) of torque at 8000rpm. The broad powerband and seamless torque curve accelerates hard and fast from anywhere on the RPM range.
72 degree V-Twin
The look, sound, and feel of a V-Twin engine delivers 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 down draft fuel intake system, thereby lowering the height of the cg 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 retainment system.
Closed loop fuel injection system, DDFI3 EFI 61mm dual throttle bodies
Immediate throttle response in any environment, that is what is delivered by the Helicon motors 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 while 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 chain-drive per cylinder 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® was able to keep the overall weight of the motorcycle extremely low.
Primary balancing with three internal shafts
By incorporating three separate primary balancing shafts into the motor - Buell® has been able to significantly reduce vibration without adding weight and complexity to the chassis.
