Best ForBest suited to riders with some prior experience who want a torquey, manageable in-line four without extreme power.
PurposeA classic 1980s sport tourer designed for confident all-day cruising with enough performance for spirited backroad riding.
Rider FitA moderate 208 kg curb weight and 790 mm seat height make it accessible to riders of average height and build.
CharacterDelivers smooth, linear four-cylinder power with relaxed sport touring geometry rather than aggressive sportbike sharpness.
Not Ideal ForNot ideal for riders seeking modern sportbike agility, off-road capability, or cutting-edge electronics and braking performance.

1984 Yamaha FJ 600 Rider Ergonomics Assessment

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 Yamaha FJ 600, 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.
