The NS400Z is the one many potential buyers are considering as their main daily commuting and regular use vehicle. The bike is attractive, promises good performance and features, but can be unreliable and may require some maintenance for daily riding. There are some users who complain of electrical problems or frequent service needs and others who praise the durability of the bike. Another factor to consider is the cost and availability of spare parts. In addition, the bike is fuel efficient and easy to maneuver in heavy traffic for daily riders. As a new model, long term reliability data is not available and so riders talk and speculate about how well the NS400Z holds up in daily use compared to more established models in its class.
