I'm planning on getting a Ninja 250. I'm 19 5'10 150 pound male. I'm getting the bike as my dd because I will be moving to Santa Monica and I don't want to deal with shitty 405 traffic in my car. I'll be using it to commute about 20 miles a day with work and school. Is this going to be practical for me? The max I have to spend on a bike is about 4k and the insurance can't be to much. Point me in the right direction guys. O yah this is my first bike.
