Apparently video is fake. A few things dont match up. Between unveiling ZX25R, and this particular vid.
1. Exhaust. No modern big 4 makes exhausts as straight cylinder pipe anymore.
2. Front fairing/windscreen. The inlet is a big giveaway, and a few other differences.
3. All the comments in the vid, saying it is in fact a 600.
I am curious as to what is the red ring is, in the exhaust, and whats protruding near it on the right. Is it a custom rear footpeg or something?
