Model Name:CYGNUS X

Manufacturer:YAMAHA

Model Year:2006

It is the 125cc motor scooter developed by YAMAHA TAIWAN based on the concept of a “tough comfort commuter”. The air-cooled OHC single cylinder engine was exclusively designed, and had a 4-valve head and a plated cylinder. It was mounted on the frame that used the compression rod method, same as the MAJESTY250. The frame absorbed any uncomfortable galloping during the drive. Its suspension was armed with an aluminum swing arm on the front/rear 12-inch tire, 90mm stroke front fork, two rear shock absorbers, and a Φ 220 front brake disc with a 2POT caliper. By placing the fuel tank under the floor, it secured enough space to hold two helmets at one time: one full-face and another half helmet. The ignition key had an anti-theft shutter, and the switches had the same design as its audio system. The front fork outer tube and the front/rear wheels were changed to black from the 2006 model. A new blue color was added to its body color instead of the silver. The sales of white and gun-metallic silver was continued.
