id go for that gs650. its a good middle ground for size and price. theres a reason there is a ton of 250 ninjas for sale. people grow out of them after a few months, and they are slow. mid 80’s 700 virago’s and maxim’s are a good learner bike too. 500-1500 for prices on those. but those are not crotch rocket style if thats what your after. if you have never ridden before, spending 2500 on your first bike might not be the best idea. especially if its on a 250 that you will surely grow out of fast. then you gotta try to sell it. and what if you drop it? better off spending 1500 or less to learn on. but thats me… good luck. and safe riding.
