This very nice bike is Billy Pentland’s 1987 YZ490 Yamaha Twinshock dirt bike. Billy took an old 1987 YZ250 Watercooled bike and converted it into a 1987 YZ490 Air Cooled open class dirt bike.
Other than the nearly one minute long intro that’s dripping cheese, these are some great vintage motocross bike videos. A lot of twin-shock & classic MX iron here!
