I’ve owned my Cygnus for about 4 years now. When I first bought it…it had a top speed of about 105…110 if I was lucky. I put in a bigger engine which helped the acceleration but it still couldn’t top 110. Then after a year or two the modified engine burnt itself out. So I threw the stock one back in. Now it had a top speed of about 95 or 100. Recently I noticed I can barely reach 90. So I take it to the Autobike shop in Chung-Li. He does some legal mods to the gears as well as replacing some parts that were starting to wear. So yesterday I’m on an open road…and the scooter flys up to 115…I’m thinking “WOW” then I realize I’m still sitting straight up…so I lean forward and the speedo starts moving again…120…125…130…and then something starts to slip so I lay off. But wow…crazy…stock 125cc scooter doing 130.
The guy at the shop has some more serious mods on his…he can do 160 with acceleration (up to 120) faster than some yellow plate motorcycles. Crazy.
