Rider Profile

Best ForSuits riders of moderate to advanced experience who appreciate classic bike manners over outright performance.
PurposeBuilt for relaxed retro-styled riding, weekend cruising, and enjoying the character of a traditional air-cooled inline-four rather than chasing lap times.
Rider FitA relatively heavy machine with a moderate seat height, so shorter or lighter riders will notice its mass at low speed and when maneuvering it off its stand.
CharacterDelivers smooth, linear power with a classic UJM soundtrack and feel, prioritizing rideability and nostalgia over aggression.
Not Ideal ForNot the right choice for riders wanting sharp sportbike handling, off-road capability, or class-leading acceleration.

2015 Honda CB1100 EX Rider Ergonomics Assessment

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

Feet:

At 795mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2015 Honda CB1100 EX, with a relaxed knee angle of around 125 degrees and a forward-leaning 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.
