BMW SIDECAR CONVERSIONS
BMW Sidecar Conversions Built by Boxer Metal
A properly designed sidecar motorcycle is unlike any other machine on the road. Equal parts motorcycle, sports car, and adventure vehicle, a sidecar outfit opens up entirely new possibilities for travel, exploration, and everyday riding.
For decades, Boxer Metal has specialized in BMW sidecar conversions, building rigs for touring, adventure travel, daily transportation, and family adventures. From vintage BMW Airheads to modern BMW GS motorcycles, we create sidecar outfits that are engineered for performance, reliability, and confidence-inspiring handling.
Every sidecar project begins with understanding how the motorcycle will be used. A touring rig has different requirements than an off-road adventure outfit, and both differ significantly from a vintage-style cruiser.
Our goal is simple: build sidecar motorcycles that are enjoyable, safe, and practical to ride.
Why BMW Motorcycles Make Excellent Sidecar Platforms
BMW motorcycles have long been among the most popular foundations for sidecar conversions.
Advantages include:
- Durable boxer twin engines
- Strong driveline components
- Excellent low-speed balance
- Wide aftermarket support
- Proven long-distance touring capability
- Strong frame designs suitable for sidecar mounting
Whether you're interested in a classic Airhead sidecar or a modern adventure rig, BMW motorcycles offer an exceptional platform for three-wheel travel.
Custom Sidecar Design and Fabrication
Every sidecar conversion is different.
Depending on the motorcycle and intended use, a project may include:
- Custom subframe fabrication
- Sidecar mounting systems
- Suspension upgrades
- Wheel and tire conversions
- Brake system modifications
- Steering geometry improvements
- Leading link front suspension
- Electrical system upgrades
- Luggage and storage solutions
- Adventure travel equipment
Boxer Metal approaches every sidecar project as a complete vehicle rather than simply attaching a sidecar to a motorcycle.
Proper setup and geometry are critical to creating a sidecar outfit that handles predictably and performs well in real-world riding conditions.
Adventure Sidecar Motorcycles
Adventure sidecars have become increasingly popular among riders seeking the ability to travel beyond paved roads.
Boxer Metal has extensive experience building sidecar motorcycles designed for:
- Long-distance touring
- Backcountry exploration
- Camping and overland travel
- Passenger comfort
- Pet transportation
- Extended expeditions
These builds often incorporate upgraded suspension systems, increased cargo capacity, improved electrical systems, and specialized wheel and tire packages.
Leading Link Front Suspension
One of the most effective upgrades for many sidecar motorcycles is a leading link front suspension.
Leading links can significantly reduce steering effort while improving handling and rider comfort. Boxer Metal has designed and installed leading link systems for numerous BMW sidecar projects and can help determine whether this upgrade is appropriate for your motorcycle.
