Im 17 but im going to do my tests and stuff next year hopefully with enough money to buy either of these new, but it's a hard choice for me and i dont know whether one is better or not. I'd primarily be using the bike to commute to and from college and work, i love the ninja but i was thinking the KLX would be a bit nippier in traffic and sticky situations, some advice on both of them would be nice, maybe a top speed and some other stuff.
It would be my first bike, so also keep that in mind.
