naked / default rider 183 cm
Aprilia Tuono 660 vs Husqvarna Motorcycles Svartpilen 401 ergonomics
Aprilia Tuono 660 and Husqvarna Motorcycles Svartpilen 401 have modeled posture scores within three points for the 183 cm default rider. Treat this as a planning estimate; posture preference, data confidence, and a real test sit still matter.
Posture overlay
The default rider's modeled seated posture on each bike, solved from the same geometry as the score panels and overlaid on one ground line so seat height and reach differences are visible at a glance.

The modeled scores are within three points, so the result does not distinguish a higher-scoring bike. Treat the result as a planning estimate and compare each bike's geometry confidence before a real test sit.
Rider fit: reaching the ground
The Aprilia Tuono 660 lists a 820 mm seat; the Husqvarna Motorcycles Svartpilen 401 lists 820 mm, within a few millimetres of each other. Seat height is only a first-pass ground-reach input. It does not establish safety or actual foot contact. Seat width, suspension sag, boots, mobility, load, and individual proportions can materially change the result.

Modeled from each bike's seat height and a typical inseam-to-height ratio only — not a flat-footing guarantee. Real ground contact still depends on seat shape, suspension sag, footwear, and your own proportions. Confirm on the motorcycle.
Verdict
Aprilia Tuono 660 and Husqvarna Motorcycles Svartpilen 401 are both naked bikes, so the practical question is which of their real differences you'd actually feel. Husqvarna Motorcycles Svartpilen 401 is about 18 kg lighter wet than Aprilia Tuono 660, which tends to show up most when paddling backward out of a parking spot or picking the bike up off the sidestand. None of that adds up to a clear overall winner in the modeled posture score, so the individual differences above are the more useful comparison than the headline number. Treat every figure here as a planning estimate: seat width, suspension sag, footwear, and your own proportions can shift the real feel more than a few millimetres or degrees on paper. Load your height and inseam into the simulator, then sit on both before you decide.
