Yamaha SR 125 weight overview
This sits at the very light end of motorcycle mass, which is especially useful when the bike has to be moved around by hand or held on uneven ground. 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 SR 125 weight FAQ
How heavy is the Yamaha SR 125?
Listed dry weight is 229.3 lb (104 kg) to 240.3 lb (109 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 SR 125 heavy compared with other Yamaha custom/cruiser motorcycles?
It is on the lighter side in this dataset. Its representative dry weight sits around the 2nd weight percentile among 26 Yamaha custom/cruiser motorcycles, meaning most compatible models are heavier.
Does the Yamaha SR 125 weight change by model year?
Not every covered year uses the same figure. The page groups identical values together and lists the later model years where the supplied weight specification changes.
How much does the Yamaha SR 125 fuel weigh?
The listed tank capacity is 2.64 US gal (10 L). Using approximately 0.745 kg/L gasoline, a full tank is roughly 16.4 lb (7.5 kg). That is an estimate for fuel mass, not an official Yamaha curb-weight calculation.
How heavy is the Yamaha SR 125 with an average-size rider?
A 180 lb rider brings the simple bike-plus-rider total to roughly 420.3 lb (190.6 kg) using the representative dry figure. Gear and luggage would add more.
Can I treat the Yamaha SR 125 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 245.7 lb (111.5 kg), and oil/coolant or definition differences may add more.
How much heavier is the Yamaha SR 125 with a full tank?
The page calculates about 245.7 lb (111.5 kg) with a full tank by adding the listed fuel mass to the dry figure. Treat this as a practical estimate, not an official Yamaha curb-weight number.
What is the Yamaha SR 125 torque-to-weight ratio?
The calculated torque-to-weight range is 3.07 lb-ft per 100 lb to 3.15 lb-ft per 100 lb. It is useful for comparing bikes with very different overall weights.
How large is the Yamaha SR 125 engine for its weight?
Engine displacement relative to bike weight is 0.51 cc per lb to 0.55 cc per lb. It can help compare motorcycles from very different displacement classes without relying on cc alone.
Motorcycle specifications can vary by model year, market, equipment and the exact dry/curb-weight definition. Calculated fuel-weight and ratio figures on this page are estimates derived from the supplied specifications.
