Rider Profile

Best ForBest suited to riders with some experience handling big, heavy cruisers, as the mass and long wheelbase demand deliberate, confident inputs at low speed.
PurposeBuilt primarily for relaxed highway cruising and long-distance touring rather than sport riding or commuting agility.
Rider FitA tall, heavy machine with a low seat height that favors riders with strong low-speed balance and decent arm/leg strength to manage parking lot maneuvers.
CharacterA classic big-inch V-twin cruiser with a torquey, unhurried powerplant, shaft drive smoothness, and a laid-back, boulevard-cruising personality.
Not Ideal ForNot a good fit for riders seeking sharp cornering response, off-road capability, or nimble city commuting.

2012 Suzuki Boulevard C109RT Rider Ergonomics Assessment

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

Feet:

At 705mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2012 Suzuki Boulevard C109RT, 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.
