The engineering of modern Triumph motorcycles, specifically the liquid-cooled 900cc and 1200cc generations, represents a sophisticated blend of electronics and mechanical precision. Unlike their predecessors, these machines rely heavily on ECU management and Ride-by-Wire technology. Enhancing a modern Speed Twin, Scrambler 1200, or Bonneville T120 requires accessories that integrate seamlessly with these digital systems. At British Legends, we focus on parts that respect the Euro 4 and Euro 5 constraints while unlocking the bike's true potential.
When selecting parts for a modern Triumph, the interface between the component and the bike's CAN-bus system is crucial. Many owners start by tidying up the rear end with a tail tidy or upgrading to LED lighting. It is important to choose lighting kits that are 'plug-and-play' to avoid dashboard errors or hyper-flashing. Brands like Motone have developed specific looms that allow you to modify the aesthetics of your Street Scrambler or Thruxton RS without cutting into the original wiring harness.
Material performance is equally important for modern performance bikes. Replacing the heavy, mass-produced steel components with CNC-milled aluminium parts or carbon fiber accents reduces unsprung weight. This directly translates to sharper handling and better suspension response. For the 1200cc High Torque (HT) and High Power (HP) engines, upgrading the exhaust headers or fitting a high-flow air filter can smoothen out the throttle response, making the bike feel more urgent in the mid-range where these engines shine.
A common misunderstanding with modern Triumphs is that any aftermarket exhaust or intake modification requires an immediate and expensive dyno tune. While the older air-cooled bikes were quite sensitive, the modern Bosch ECU is capable of adapting to minor changes in airflow within certain parameters. However, when removing the catalytic converter or installing a full system, the sensors will detect a significant shift in backpressure. In these cases, we recommend specific solutions that maintain the engine's health and prevent it from running too lean at high temperatures.
A practical example is the installation of adjustable levers or footpegs. On modern models with cruise control or quickshifters, the tolerances are much tighter than on older bikes. A lever that doesn't fully return to its neutral position can prevent the cruise control from engaging. Therefore, we only offer components that are specifically engineered for the latest generations of the Speed Twin and Bonneville, ensuring that all electronic safety features continue to function exactly as the factory intended.
Generally, fitting a 'slip-on' silencer does not void the overall warranty, provided it doesn't cause a direct engine failure. However, more invasive modifications like removing the catalytic converter might affect specific parts of your warranty. Always keep your original parts so the bike can be returned to stock if needed for official service intervals.
Although they look similar, the frames and mounting points often differ. The 1200cc models usually feature wider swingarms and different fork diameters. We categorize our parts strictly by engine size and model year to ensure you receive a component that fits perfectly without modification.
The primary benefit is heat reduction. The catalytic converter sits right under the engine and radiates significant heat towards the rider's legs. An X-pipe allows the exhaust gases to flow more freely, reducing the operating temperature and giving the bike a deeper, more authentic twin-cylinder sound.
