For the 2005 model year, the Ducati ST4 S motorcycle has a listed dry weight of 443.1 lb (201 kg).
Ducati ST4 S weight overview
This is neither unusually light nor extremely heavy. For most riders the practical weight question is more about seat height, center of mass and low-speed balance than the scale number alone. The comparison uses dry weight because a usable wet/running figure was not supplied, so the actual ready-to-ride motorcycle will be heavier.

Ducati ST4 S weight FAQ
How heavy is the Ducati ST4 S?
Listed dry weight is 443.1 lb (201 kg). Because no usable wet/running figure was supplied, treat that as a lower starting point rather than the exact on-road weight.
How much does the Ducati ST4 S fuel weigh?
The listed tank capacity is 5.55 US gal (21 L). Using approximately 0.745 kg/L gasoline, a full tank is roughly 34.5 lb (15.6 kg). That is an estimate for fuel mass, not an official Ducati curb-weight calculation.
How heavy is the Ducati ST4 S with an average-size rider?
A 180 lb rider brings the simple bike-plus-rider total to roughly 623.1 lb (282.6 kg) using the representative dry figure. Gear and luggage would add more.
Can I treat the Ducati ST4 S dry weight as curb weight?
No. The usable figure is dry weight, so it excludes at least some operating fluids. Dry weight plus the estimated full fuel load is about 477.6 lb (216.6 kg), and oil/coolant or definition differences may add more.
How much heavier is the Ducati ST4 S with a full tank?
Based on the available dry-weight and tank-capacity data, a full-tank estimate is 477.6 lb (216.6 kg). Oil, coolant and market-specific equipment can still make actual ready-to-ride weight different.
How much torque does the Ducati ST4 S have per 100 lb?
The calculated torque-to-weight range is 17.48 lb-ft per 100 lb. It is useful for comparing bikes with very different overall weights.
What is the Ducati ST4 S displacement per pound?
Engine displacement relative to bike weight is 2.25 cc per lb. It can help compare motorcycles from very different displacement classes without relying on cc alone.
Will the Ducati ST4 S feel heavy at low speed?
It is most likely to feel heavy while stopped, backing up or on a slope rather than once settled at normal riding speed. Seat height and center of gravity matter a lot.
Motorcycle specifications can vary by model year, market, equipment and the exact dry/curb-weight definition.
