- My name is Kimberly and I have this big motorcycle engine left in my backyard patio. I have recently been informed from the serial number that this is a 1992 aspencade or SE. History: a friend's husband died after he fell on his other bike and hit a curb. I ended up with all his goldwing stuff to sell. What is left is this engine. I'm selling it for $150. I don't have any information on this engine other than what I posted.
