I owned a 91 andit for about 4 years. he only mods were drag bars turned down slightly. Really helped with the flickability in the twisties. I also opted for a 120/60 front and a 160/60 rear. I bought Battlax scuffs off a race CBR600F2. I second the notion that it kills the power when someone is on the rear. But single I constantly waxed Katana 6´s in the straights and when the road gets rea twisty I could hang with the big boys. It takes alot of shifting to get it in the sweet spot but that is what makes it fun. It is a great starter bike. Not powerful enough to wheelie without really wanting too and very light and nimble. If I hadn´t put on so much weight I would get another one now. I was 160 then but now am a tad over 200.
