Performa motor bakar dipengaruhi oleh kondisi pengoperasian mesin, salah satunya adalah putaran mesin dan pembebanan. Pengujian performa diperlukan untuk mengetahui karakteristik kerja motor bakar sehingga dapat diketahui perubahan torsi, daya, dan efisiensi pada kondisi operasi yang berbeda. Tujuan riset ini adalah menganalisis pengaruh variasi putaran mesin terhadap performa motor bakar Daihatsu Zebra Espass 1000 cc berbahan bakar Pertamax berdasarkan parameter Rpm, torsi, daya keluaran, dan efisiensi. Riset dilakukan dengan metode eksperimen menggunakan dynamometer pada variasi putaran 1500, 2000, 2500, dan 3000 Rpm dengan beberapa kondisi pembebanan. Hasil riset menunjukkan bahwa pemberian beban menyebabkan Rpm aktual mesin mengalami penurunan, sedangkan torsi, daya keluaran, dan efisiensi mengalami peningkatan seiring dengan kenaikan variasi putaran. Nilai torsi tertinggi diperoleh sebesar 25,5 N.m pada target putaran 3000 Rpm, sedangkan daya keluaran tertinggi sebesar 73,26 HP pada target putaran 3000 Rpm. Nilai efisiensi tertinggi mencapai 61,97 % pada target putaran 3000 Rpm. Hasil riset ini dapat menyajikan gambaran tentang karakteristik performa motor bakar berbahan bakar Pertamax pada variasi putaran dan pembebanan serta menjadi referensi dalam pengujian performa motor bakar.
