Abstract

Pada Modifikasi sepeda motor dengan komponen aftermarket, seperti knalpot racing dan ECU programmable, telah menjadi tren populer untuk meningkatkan performa mesin tanpa mengubah komponen orisinal. Penelitian ini bertujuan untuk menganalisis efek penggunaan tiga jenis knalpot (standar, racing bulat, racing trioval) dan pengaturan ignition timing (IT) dengan empat tingkat (standar, IT STD +2°, IT STD +4°, IT STD +6°) terhadap daya, torsi, efisiensi bahan bakar, dan emisi gas buang pada sepeda motor Yamaha Vixion 2011. Metode eksperimen dilakukan dengan pembagian 12 kelompok perlakuan menggunakan dynamometer dan gas analyzer untuk pengukuran data. Hasil menunjukkan bahwa IT STD +4° adalah pengaturan terbaik untuk knalpot standar, sedangkan kombinasi knalpot racing Bulat atau Trioval dengan IT STD +2° memberikan performa optimal, menghasilkan daya maksimum hingga 17,2 HP. Penelitian ini menyimpulkan bahwa kombinasi knalpot racing dan pengaturan IT yang tepat mampu meningkatkan performa mesin sekaligus mempertimbangkan efisiensi bahan bakar dan emisi gas buang, yang diharapkan menjadi referensi bagi pengguna dan produsen komponen aftermarket

Motorcycle modifications with aftermarket components, such as racing exhausts and programmable ECUs, have become a popular trend to enhance engine performance without altering the original components. This study aims to analyze the effects of using three types of exhausts (standard, round racing, trioval racing) and four levels of ignition timing (standard, IT STD +2°, IT STD +4°, IT STD +6°) on power, torque, fuel efficiency, and exhaust emissions of a 2011 Yamaha Vixion motorcycle. The experimental method was conducted by dividing the test subjects into 12 treatment groups, utilizing a dynamometer and gas analyzer for data measurement. The results showed that IT STD +4° was the best setting for the standard exhaust, while the combination of round or trioval racing exhausts with IT STD +2° provided optimal performance, achieving a maximum power output of up to 17.2 HP. This study concludes that the combination of racing exhausts and appropriate ignition timing settings can significantly improve engine performance while also optimizing fuel efficiency and reducing exhaust emissions, making it a valuable reference for both users and manufacturers of aftermarket components.
