In the one extended scene where Richie wants to buy it back from the guy he sold it to for $1800. The guy tells him he will give him a Yamaha with a busted Trannie for the $1800. But he now wants $2400 for Richie bike. Richie threatens to set them on fire. He caves and gives Richie his bike back.
After researching it closer and finding pictures. Myself and others decided that the bike was around a 1982 Honda CB900.
