History
In shed for many years unridden, owner paid rego for 20 years so it was current when purchased ( God bless him ). Amens are rare in Oz and even rarer with rigid frame, most were the Saviour model with a plunger rear suspension known for the wobblies when worn. Awesome bike to ride, I love it.
Modifications
How long have you got, but all are American Motorcycle Engineering ( AMEN ) produced.
