It really down to if you want crazy top end power and speed. I had an MT-09 and it was crazy fast. I was literally gonna get arrested on that thing if I kept it. lol So I got an GSX8S and it’s just perfect! Amazing low end torque, crazy smooth, and looks really good. The biggest difference is the powerband. The mt09 really takes off once you hit 7-9k rpm while the GSX8S runs out of power up top. The GSX8S low/mid end does hit way sooner and gives me the same thrill but I’m not going 90mph on one wheel and hitting 120mph by the time I can blink. Lol So it really down to what you want out of an bike and I wouldn’t even worry about which bike is better. Both are amazing bikes, just ride and have fun! Heck I also got an Kawasaki W800 and that thing isn’t fast at all and literally handles like an bike from the 60’s but I freaking love it for crushing around town. lol
I am riding a mt-09 sp and am dissatisfied with the feel of the 3 cylinder. However, the GSX-8S's two-cylinder engine left a very good impression. but, I love the sound of Suzuki's 4-cylinder. クルコンあるのでmt-09 SPも悪くはないですよ
