In 2012 Buell continues to focus on the ride with the addition of features like front brake master cylinder piston seals and rotor mountings, LED taillights and rear turn signals, oxygen sensors and tyres, as well as new graphics and bodywork. Whether it’s the 1125cc Helicon® liquid-cooled, four-stroke, fuel-injected 72-degree V-Twin engine or the 1203cc Thunderstorm™ air/oil/fan-cooled, four-stroke, fuel-injected 45-degree V-Twin engine, Buell blends original design with productive power and dynamic performance for a light and tight ride.The 1125R belt drive system is a few pounds lighter than a comparable chain and sprocket system. The lower unsprung weight improves throttle response and increases overall drive performance. Surprisingly, belts can last a lifetime with no maintenance or required adjustments, providing rocks or similar debris does not get caught up in the belt. The belt was also extremely smooth ride. One limitation may be the ability to change the final drive ratios, as the system is fixed.
