Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.

SUZUKI MOTORCYCLE: AN ASSEMBLY GUIDE WILL NOT BE ISSUED FOR THE VZR1800NK9, BECAUSE THE SET-UP PROCEDURE REMAINS SIMILAR TO THE VZR1800K6. TO SET UP A VZR1800NK9, PLEASE USE THE VZR1800K6 ASSEMBLY AND PRE DELIVERY GUIDE AND THE ADDITIONAL INFORMATION OUTLINED I N THIS BULLETIN. *PE
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
