You could ask the same question to Yamaha, suzuki and Kawa ownwers!!!! I have a NSR becasue when i was looking for a 2 stroke everyone has a rgv or the aprillia, the KR1's is nice but i heard it had reliablity problems i didnt know of any NSR's until a freind told me about them then when i saw a MC21 i knew it was right, 2 stroke, looks cool as, and its a HONDA, I really like the Yams to but it would have to be the chocolate engine reverse cylinder or the 3xv for me otherones look GUFF!
