Abstract
Various researches have been carried out on how to increase the torque and power of automatic motorcylce. One interesting thing is the addition of a needle thrust bearing to the Continously Variabel Transmission (CVT) spring. This study needs to be researched so that the impact of using needle thrust bearings on CVT springs has an influence on the torque and power of automatic motorbikes. The research aims to calculate the impact of the influence of adding Needle Thrust Bearings installed on motorcylce CVT springs on the torque and power produced. So a study will be given to see whether the addition of the needle thrust bearing component has a sufficient/significant/large influence on the torque and power of the motorbike. Tests were carried out with the help of a Super dyno 50L brand dynotest tool. The test was carried out three times by paying attention to the engine rotation factor (rpm) as a reference. The test results show that by using a set of Needle Thrust Bearings on CVT springs, there is an average increase in torque of 5.32% and an average increase in power of 5.84%.
