The vast majority of Outlaw Motorcycle Clubs (OMCs), including 1%er clubs, have a strong association with Harley-Davidson motorcycles. Harley-Davidson has become an iconic brand within the motorcycle club culture, and many OMC members ride Harley-Davidson motorcycles as a symbol of their club affiliation and identity.
While it is less common, there may be individuals within outlaw motorcycle clubs who choose to ride motorcycles from other brands, such as Honda, Yamaha, Suzuki, or other manufacturers. These cases are generally exceptions to the norm and can vary depending on the specific club, its rules, and the personal choices of its members.
It's worth mentioning that motorcycle club culture is diverse, and not all motorcycle clubs adhere to the traditional outlaw image or the 1%er ideology. There are various types of motorcycle clubs with different focuses, and some of them may have different brand preferences or riding styles.
To get more specific and up-to-date information on the practices and preferences of different motorcycle clubs, it would be necessary to research individual clubs or consult motorcycle club enthusiasts and experts who have knowledge of the current landscape within the motorcycle club culture.
