How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's best suited to relaxed commuting and light weekend rides rather than long-distance touring or performance riding.
- Built for
- The GN400 has a laid-back, honest single-cylinder thumper personality typical of early-80s simple, low-maintenance touring bikes.
- Not ideal for
- It's not for riders seeking high speed, off-road capability, or serious two-up long-distance touring comfort.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
