I bought and installed these on my 2007 SV650. Given the fact that my bike isn't known for top end I figured these would be a great way of adding some... I was very correct! Unlike most inline 4 bikes that only gain a little top end and a cool intake sound, my little v-twin gained a nice amount of mid and top end with no sacrifice to the lower rpm's. I love the added pull I get when my torque runs out and the power picks up. What use to feel like a flat spot in the higher rpm's is now more acceleration.
These are a definite must for anyone looking to get every little bit of power out of their machine with bolt-on's only.
