Motorcycle is the main transportation in urban and rural areas nowadays. Many users have not satisfied with performance of standard manufactured. The objective of this research is to improve motorcycle performance by modifying the camshaft duration. The research was conducted at Combustion Laboratory of Department of Mechanical Engineering Faculty of Engineering. The standard of camshaft duration is intake valve 221° LSA, 96.75° and exhaust valve 202° LSA 84°. The first modification camshaft is intake valve 235° LSA 100.5° and exhaust valve 235° LSA 102.5°. Second modification camshaft is intake valve 260° LSA 104° and exhaust valve 260° LSA 107°. The results of experiment show the good engine performance was in the second modification. Increased of torque are 19.182% and 22.902% for the first and second modification respectively. Moreover, increased of power are 7.378% and 13.45% for the first and second modification respectively.
