This TNG Milano (China knockoff of the Yamaha Vino 125) has one improvement over the original - the rear seat backrest! I finally found some pricing for this and it's not cheap.

Parts look exactly the same as the Yamaha Vino 125, huh? I'm not even sure the backrest is compatible, but it sure looks like it!

The bracket is sold separately from the leather piece: $34.93 + 24.50 + tax + shipping ends up to be around $80!

Way too much especially since I don't plan on having a passenger 99.5% of the time.
