I currently ride a Ninja 250, but have decided on purchasing a TZR 250 to ride next spring. I love 2 strokes, and the weight/horsepower ratio is just what I'm looking for. But I want to know from all TZR owners out there, the pros/cons of that bike. Because they are high performance, do they tend to be tempermental, are they reliable, what parts wear out or breakdown generally, and etc? Any info would be greatly appreciated.
