Rider Profile

Best For	A confident beginner or returning rider will feel comfortable, though the mid-size four-cylinder power delivery still rewards some prior riding experience.
Purpose	Built as a shaft-driven sport tourer, this bike suits relaxed weekend rides and moderate-distance touring rather than outright performance riding.
Rider Fit	The 790mm seat height and moderate 197kg dry weight make it approachable for riders of average height and build, with manageable low-speed handling.
Character	It has a smooth, classic air-cooled inline-four character with linear power delivery and shaft-drive reliability rather than aggressive urgency.
Not Ideal For	This is not the bike for riders seeking modern sportbike acceleration, aggressive cornering clearance, or any off-road capability.

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

Feet:

At 790mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 1984 Honda CB 650 SC Nighthawk, with a cramped knee angle of around 70 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.
