Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“About 10:30 pm while en route to work I was riding on the freeway at the posted speed limit and I noted flashing lights appearing on the speedometer- the low fuel lamp and electrical system lamp. I pulled over the emergency lane right away to make any assessment. I was able to exit the freeway to secure a safer environment for me. The flashing low fuel lamp and electrical system lamp persisted. I called for my towing service the following morning because I didn't think it would be safe to drive the motorcycle home. …”
