Sold my 99 Katana 750 this weekend. Bought it for $1600 back in 2013 at 9k miles, sold for $2200 w/16k miles.
No garage queen but rock solid bike.. heavy, too.
I will miss it once in a while.. like many of my bikes, it needed very little care: fuel, lube and go.
Performance of the 750cc air-oil cooled engine is just fine for the streets in capable hands.
If I find another one in decent shape and low price, probably will buy again.
