Kawasaki 250r are simply pricey of course but that blade250r are basically worthless imo..it had problematic with efi sensor, stand switch malfunction, bad cable clutch housing, harsh engine n gearbox shifting,  bad air cool system, loosing screw n nuts dropping out, soft monoshock, super high preload monoshock for big bike feel, super big tyre for so called big bike feel but weak n soft monoshock...those problems are identifiable and happens for user that uses less than 5k km...honestly I rather pay the extra 10k n get a safer bike...
my 25cent opinion only
