Honda SP125 weight FAQ
What is the Honda SP125 wet weight?

How much of the Honda SP125 total weight comes from fuel?
The calculated full-tank fuel mass is about 7% of the listed motorcycle weight. Because the available basis is wet/running weight, that fuel is already included in the ready-to-ride figure.
How does Honda SP125 torque compare with its weight?
Where compatible torque and weight figures are available, the model works out to 3.12 lb-ft per 100 lb. This gives more context than torque alone because it relates engine twist to the mass it has to move.
What is the Honda SP125 engine-size-to-weight ratio?
