NHTSA Service Bulletin 10172891: 2018 Ubco 2x2
Official manufacturer communication context for 2018 Ubco 2x2, with affected products, buyer checks and links into Carchieve recall, problem and VIN research.
Reviewed June 2026 from NHTSA manufacturer communication and service bulletin records. Carchieve is independent and not affiliated with any vehicle manufacturer or government agency.
A number of failures of the speedometer housing & wiring connection have been reported on bikes with VIN numbers between J600001 to J600581. The failure mode has been identified as being excessive vibration from the handle bars passing through to the mounting bolts of the speedometer. This can cause the display not to function correctly. It also has been noted that in certain cases that when the bike is turned off or power removed from the clock, the time on the clock resets back to zero. This is the result of a missing capacitor on the PCB. A speedometer is supplied to resolve this.
