4 sizes/capacity types, and how to choose from]
Road Traffic Law violates if a motorcycle backbox is protruding too much out of the vehicle.
This is prescribed by the Road Traffic Law Enforcement and must comply with the following rules:
Length: Do not exceed 30cm from the passenger or the loading device.
Width: Within 15cm on each side of the passenger or load device.
When determining the capacity of the rear box, take into account the amount of motorcycle displacement.If you install a large capacity rear box on a small discharge motorcycle, it may be hard to balance.
If you are commuting to work or school, it is sufficient for a 7.5 - 10.8 gal (25 - 35 L), but if you want to enjoy a long touring or sleeping in the car, we recommend the 16.9 - 12.3 gal (45 - 55 L) case.(Measurements depend on capacity of 25L/45L/55L/65L are as pictured)
