Yamaha Crux

CRUX 106

The Yamaha Crux is a 106 cc, single-cylinder four-stroke motorcycle made by India Yamaha Motor. The Crux is designed for Indian markets. It was launched in 2004 replacing RX 100, as 2-Stroke engines were not able to meet government's emission norms. Other Yamaha motorcycles such as the YBR 110, earlier known as Alba 106 and Libero (G5) share the same refined engine. Unlike YBR 110, Crux has round head lights which give it a classic look. A different version of Crux known as Crux R and Crux S were introduced with the same specifications but rectangular headlights. But after it could not make a considerable sales, the production was halted. User and owner claimed mileage and topspeed is 55kmpl and 95kmph respectively.
