There is a 500-Wh downtube battery, and riders are additionally handled to a minimalist Interface X management unit with easy swap energy adjustment, three-color LED help indicator, battery standing and Bluetooth connectivity.
This birthday version wears a "distinctive polished aluminum end" together with Yamaha Racing blue rocker hyperlink and headtube, a thirtieth Anniversary badge and commemorative decals. The restricted manufacturing run ships to US sellers from June 1, and is priced at US$6,499 – 100 bucks greater than the usual YDX-Moro 07 mannequin.
