⚠️ Things to consider

• Limited Power Output: With a 350cc engine, the NSU 351 OSL may feel underpowered compared to modern motorcycles, making it less suitable for highway cruising or aggressive riding.
• Heavy Weight: The design and materials used in the 1934 model contribute to a heavier overall weight, which can affect maneuverability and handling, especially for newer riders.
• Parts Availability: Given its age and rarity, finding replacement parts or accessories for the NSU 351 OSL can be challenging and potentially expensive, complicating maintenance and repairs.
• Braking Performance: The braking system on vintage motorcycles like the NSU 351 OSL may not meet modern safety standards, leading to longer stopping distances and less confidence in emergency situations.
• Comfort and Ergonomics: The riding position and seat design of the 1934 model may not provide the same level of comfort and ergonomics that contemporary motorcycles offer, which can lead to discomfort on longer rides.
