From 2021 Euro 5 set stricter limits on emissions of nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter for motorcycles. These regulations aim to reduce the environmental impact of motorbikes, ensuring cleaner air and a healthier environment.

As a result of Euro 5 standards, many motorcycles run lean and hot at low RPMs. This can lead to poor throttle response and increased engine wear, affecting overall performance and longevity.

Bikefuel Pro optimises the fuel mixture, enriching it in the lower to mid RPM range to counteract the lean running caused by Euro 5. This results in a cooler, smoother engine performance with significantly improved throttle response.
