Rider Profile

Best ForA good fit for newer riders or those moving up from a smaller displacement bike who want a manageable but engaging middleweight naked.
PurposeBest suited to daily commuting, urban riding, and casual weekend backroad fun rather than dedicated touring or track use.
Rider FitThe 780mm seat height and 206kg curb weight make it approachable for riders of average or shorter stature to handle confidently at low speeds.
CharacterA practical, no-nonsense parallel-twin naked bike offering modest power delivered smoothly, with a focus on affordability and everyday usability over outright performance.
Not Ideal ForNot the right choice for riders seeking long-distance touring comfort, serious off-road capability, or track-level performance.

Rider Fit Visualizer

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

Feet:

At 790mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2018 CF Moto 650NK, with a relaxed knee angle of around 120 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.
