Company History
Yuki imports and finishes globally manufactured 50–250 cc machines for regional needs—winterized electrics, EU compliance, and localized gearing. Dealer networks stock consumables and panels, keeping student and commuter bikes on the road. The brand’s value is predictable ownership: documentation in local language and parts on the shelf.
