Exhaust system: Upgrades to the exhaust system may be necessary to accommodate the changes in the engine. This can include the addition of a larger or more efficient catalytic converter or the introduction of additional baffles or silencers to reduce emissions.
Fueling system: Motorcycle manufacturers may update the fueling system, such as the fuel injection mapping, to ensure optimal fuel-air mixture and minimize emissions while maintaining performance.
Compliance with regulations: Apart from engine-related changes, manufacturers may make adjustments to other components to ensure compliance with additional regulations, such as noise levels, safety standards, and on-board diagnostic systems.
Design updates: During transitions, manufacturers sometimes take the opportunity to update the overall design of their motorcycles. This can include cosmetic changes, ergonomic improvements, and the introduction of new features or technologies.
Please note that specific changes made by Royal Enfield during their transition to BS-VI may vary depending on the motorcycle models and their respective requirements.
