Rider Profile

Best ForThis is a machine best suited to experienced riders who understand three-wheel dynamics, as the Gold Wing-based trike conversion handles very differently from a two-wheeled motorcycle.
PurposeBuilt for long-distance, high-comfort touring where stability, luggage capacity, and a relaxed ride matter far more than outright speed or cornering agility.
Rider FitDespite its considerable bulk, the trike layout eliminates the need to balance or hold up the machine at stops, making it accessible to riders who might struggle with a heavy two-wheeled tourer.
CharacterA stately, boulevard-cruising trike that trades sportiness for effortless, planted highway comfort and Gold Wing-grade smoothness from its six-cylinder boxer engine.
Not Ideal ForNot for riders seeking spirited cornering, lightweight agility, or any off-road capability, as its width, weight, and three-wheel format rule out tight handling and rough terrain.

2010 Lehman Trikes Monarch II Gold Wing Rider Ergonomics Assessment

Calculated in your browser only - your height/inseam are never sent to our servers.

Feet:

At 739mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2010 Lehman Trikes Monarch II Gold Wing, with a cramped knee angle of around 80 degrees and a slightly forward riding position.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
