Because i got my FS1E in 1976, and followed that with an RD250 (blue, coffin tank!) and then an XS750 US Custom.
Then had a break (got married!) and returned to bikes about 10 years ago with a 1967 XLCH Harley.
When I sold that, I wanted to get back to a more modern bike, and nothing but Yamaha crossed my mind
Have now got a 97 Thundercat and it does everything I need in all weathers perfectly
