Yamaha XJR 400 R 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.

Yamaha XJR 400 R weight FAQ
How heavy is the Yamaha XJR 400 R?
Listed dry weight is 388 lb (176 kg). Because no usable wet/running figure was supplied, treat that as a lower starting point rather than the exact on-road weight.
Is the Yamaha XJR 400 R heavy compared with other Yamaha naked bikes?
It is on the lighter side in this dataset. Its representative dry weight sits around the 18th weight percentile among 17 Yamaha naked bikes, meaning most compatible models are heavier.
How much does the Yamaha XJR 400 R fuel weigh?
The listed tank capacity is 5.28 US gal (20 L). Using approximately 0.745 kg/L gasoline, a full tank is roughly 32.8 lb (14.9 kg). That is an estimate for fuel mass, not an official Yamaha curb-weight calculation.
How heavy is the Yamaha XJR 400 R with an average-size rider?
A 180 lb rider brings the simple bike-plus-rider total to roughly 568 lb (257.6 kg) using the representative dry figure. Gear and luggage would add more.
How much horsepower does the Yamaha XJR 400 R have per 100 lb?
Where compatible power and weight figures are available, it works out to 13.66 hp per 100 lb. That places it around the 19th percentile within the compatible Yamaha naked bike power-to-weight comparison.
Can I treat the Yamaha XJR 400 R 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 420.9 lb (190.9 kg), and oil/coolant or definition differences may add more.
What is the estimated Yamaha XJR 400 R weight with a full tank of gas?
Based on the available dry-weight and tank-capacity data, a full-tank estimate is 420.9 lb (190.9 kg). Oil, coolant and market-specific equipment can still make actual ready-to-ride weight different.
How much torque does the Yamaha XJR 400 R have per 100 lb?
The calculated torque-to-weight range is 6.65 lb-ft per 100 lb. It is useful for comparing bikes with very different overall weights.
What is the Yamaha XJR 400 R displacement per pound?
Engine displacement relative to bike weight is 1.03 cc per lb. It can help compare motorcycles from very different displacement classes without relying on cc alone.
