I have had on 03 Katana (Kan-o-tuna) for about 4yrs now. Traded an old Springfield SAR-8 pinner for it. Commuter bike for me, gets about 55mpg compared to my GT which gets about 15 with the way I drive it. Not SQUID worthy but it's a comfortable ride with decent mileage and pep.
Reminds me I need new tires this season.
