Hello everyone. I was looking for some info on my ne 76 CB550 and found this awesome sight. I live in Central Michigan, 1hr north of Grand Rapids Michigan. I picked up a 76 CB550 GRC. Grand Rapids Chopper. It was an option from a local dealer Gars Honda. It has a king queen seat, 6 inch over forks and a high handle bar. The bike was bought from a collector with 5600 miles on it and in extremely nice condition. With some elbow grease it will be an 8.5 on a 1-10. The Corbin king queen seat is mint as is the original Honda seat. The dealer took the stock seat off and replaced with the corbin seat. They put the stock seat in a bag and then boxed it up to rest there until I bought the bike. The bike was always in a heated garage/showroom. The corbin seat is mint as well however I think I will put the bike back to factory original over the winter. The bike had sat idle for 3 years, I cleaned it up, fresh gas, cleaned the carbs and synced them and its a runner. I will post a pic later.
