If you own the metallic red version of the KYMCO Bet & Win 150 and are in need of some touch-up paint, the KYMCO part # is RR004 ("RR" stands for Ruby Red). The metallic red on the B&W 150 and the B&W 250 are apparently the same or as far as I have been able to find out. I only know that on the KYMCO USA website, the part # for red touch-up paint is only listed for the B&W 250 and is the aforementioned part #. A nail polish-sized bottle was $8.13 from my local KYMCO dealer.
Hope this helps someone!
