they all go the same when you’re riding them 
- Service, reliability, parts cost, etc … From what I understand, kawasaki produce less bikes than Suzuki, so parts and servicing could cost more? But don’t quote me on this.
Anyhow, why ask us? We are not buying the bike, nor the ones having to live with it … go with your heart, not by what other people think!
Which one would put a smile on your face, every time you sat on it?
I bought an R1, even though people were suggesting otherwise, and I have never looked back! :D:D
I would def have the GSXR I have been on both and the gsxr is a much much better bike in my opinon. The GSXR looks a hell of lot better to!
