Dear Experts,

Need your valuable suggestion for upgrading from a CBR 250r ABS 2012 model to a higher CC bike.

Below listed are some bikes that I am considering.

1. Apache RR310 (not a huge upgrade from CBR 250)
2. Kawasaki Ninja 650r
3. Kawasaki Z650
4. Suzuki GSX S750

Please share your feedbacks & suggestions to pick a good one,
I have had the CBR for 6 years. It's still rocking but I am feeling its not powerful enough on highways.

Major usage:
* Highways ride
* City ride in weekends

Thanks in advance
