The 599 is better on build quality, but give that Suzi a look. It's as popular in the States as the Hornet 600 is in Europe, and for good reason. I literally lined up an SV-650 against the 919 when I was shopping. The Suzi is better handling on technical courses, and you get the midrange torque, due to the V-twin. But when I put the two bikes side by side I bought the Honda. My 919 was made in Japan, btw, I think the 599s imported to the States are built in Italy.
They're both great bikes, but line them up side by side.
