DIAMONADO MOTORCYCLE SIDECARS
The Diamonado® is a fully articulating sidecar system that preserves the core dynamics of motorcycling—leaning and countersteering—while adding the stability of a three-wheeled platform. With a low center of gravity and a caster-style sidecar wheel, it delivers a smooth, controlled ride that feels intuitive and responsive. Designed for comfort, handling, and versatility, the Diamonado offers a touring experience that sets it apart not only from rigid sidecars, but also from trikes and traditional touring motorcycles. It’s a developed solution for riders who want the added stability of a three-wheel vehicle without giving up the ride quality and dignity that makes motorcycling special.

With its hybrid architecture, the Diamonado challenges the long-standing compromises in three-wheel vehicle design. It blends the natural, dynamic handling of an articulating sidecar with the planted feel utility of a rigid platform—while leaving behind the limitations of both. The result is a refined system that delivers an elusive balance of performance, stability, and rider enjoyment.

Features & Benefits
The Diamonado’s robust design supports a traditional sidecar layout while achieving a low center of gravity—resulting in better weight management when the vehicle is loaded.
Mounting points are positioned along the motorcycle’s centerline, allowing the brackets to maintain a clean, integrated appearance.
The leaning wheel assembly incorporates a motorcycle tire and a traditional motorcycle swing arm carried by a structural wheel fender. This creates a compact, rigid assembly.
Parallelogram geometry ensures all leaning components operate at a 1:1 ratio. Combined with the sidecar’s slender body and wheel assembly, this allows all three leaning elements to be positioned in close proximity.
The Diamonado’s main frame, when connected to the mounting bracketry, functions similarly to a suspension control arm. This design helps absorb vertical deflection forces—reducing the kind of feedback typically experienced in rigid 3-wheel configurations.
All three tires on a Diamonado vehicle are not forced to wear to a flat pattern like a rigid sidecar.
The wheel assembly functions like a caster. The wheel freely tracks a path of least resistance independent from the tracking of the motorcycle. Some benefits of this design:
- Reduces tire scrub
- Minimizes tire wear
- Improves fuel economy
- Reduces harsh feedback by a sudden lateral force against the tire
- Perfect motorcycle to sidecar alignment during installation is not required, making it a one-time event. There is no need to continuously make adjustments to try gaining improved performance.
A double hoop pivoting assembly is independent of the mounted body structure. This keeps structural members from invading the passenger compartment and allows for easy removal of the body.
The sidecar is easily detached to restore the motorcycle to its original use.
No frame modifications are made to the motorcycle.
The sidecar body enhances the passenger experience by offering:
- An unobstructed view
- Better protection from the elements
- Comfortable seating position
- Allowance for different body positioning
- Adjustable footrest
- Large locking storage space behind the seat
- Large storage space ahead of the footrest
- Dash pocket with device port
Patents:
- Patent #1: Granted - relates to suspension on our sidecar design
- Patent #2: Granted - relates to the use of electrical components for the positioning system on a leaning sidecar.
- Patent #3: Granted - relates to the use of electrical components for the positioning system on all leaning vehicle designs which includes sidecars and leaning trikes. This concept makes it possible to safely transition to the leaning mode at higher speeds than what is currently available on the market.
