What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Functional Impact: Complete loss of brake light signaling during routine, light, or progressive front-wheel braking maneuvers.
It hesitates, and chugs very rough, before finally settling down. It isn't right. Admittedly, I haven't taken it to the dealer, beyond the initial service at around 700 miles. The dealer who serviced the bike said it should calm down with more miles. It hasn't.
When cold, first start of day, subject motorcycle engine does not run consistently / stumbles /stalls at start up and drive off. Safety issue for me is the stumbling and stalling making motorcycle unpredictable while entering traffic flow. The issue occurs at every cold start. If engine is warm, no issue noted.
