This list looks at ten well-known motorcycle brands. These brands often receive higher-than-average complaints from riders worldwide. The complaints range from electrical faults to weak customer service. Some brands struggle with expensive repairs and rare spare parts.

Keep in mind that no brand is perfect. Even top-rated brands receive some complaints from unhappy customers. However, some brands appear far more often in complaint discussions.
This list ranks them from least to most frequently mentioned. Read on to understand what riders commonly experience. This can help you make a smarter buying decision.
10. Suzuki
