When Yamaha unveiled the , often dubbed the "Jungle King" or "V-ixion" in certain markets, it redefined what riders expect from a 155cc naked sport motorcycle. With its variable valve actuation (VVA) technology, a liquid-cooled engine derived from the R15, and aggressive street-fighter aesthetics, the Y16ZR is a high-strung piece of engineering.
