I recently fixed up a 1980 CB400t Hawk that I found sitting in a barn. Rebuilt the carbs and she´s a beauty. She still needs a little more work to get her as beautiful as she was in 1980, but she´s come a long way so far. The tires have to be replaced due to dry-rot for sitting for the past 10+ years. I saw on this website the dimensions for the tires. I was wondering, if anyone knew a cheap place to buy tires for the bike via online purchase. Thanks for any info. On a side note. I was thinking about putting different handle bars on the bike, if anyone knew a cheap place to purchase that too that would be appreciated. Thanks again
