New here - but my first bike is a `09 Ninja 650r.
My husband fully supported, well, he actually encouraged this purchase, as he also said I wouldnt be happy with a 250 long term.
I also wanted something to keep up with his VFR800 on longer travels.
I'll admit it took a few extra hours to get used to the extra height and weight, compared to riding lessons on a 250), but I definitely am happy I went with it.
My bike isn't panting behind him on the highway, and is large enough to carry luggage on longer trips!
Best of luck - and just take it slow and easy at the beginning!
