I believe the NC250 engine has proven itself reliable. This engine has been in production for several years, and it has been installed in a number of different Chinese dirt bikes, dual sport bikes, and street bikes.

The Delphi EFI system is from the United States. Therefore, spare parts and U.S. service centers are readily available. The NC250 engine employs the Delphi MT05 ECU. Here's a link to the Delphi Small Engine Management System Service Manual.
