Mospeada Translation Help

走行距離：約３８０km（HBT３号チューブ１本あたり）
This line is from the "Data" section on the Mospeada transforming motorcycle in Genesis Climber Mospeada. I translated it as:
driving distance: about 380km (one tube of type 3 HBT)

How would someone more knowledgable translate it?
Thanks.

Well, it's basically range on a single tank of gas, right? ~380km for one #3 tube of HBT. Anyone know if there's a common name for that in English vehicle catalogs?

Thanks for the reply. It appears my understanding of the line wasn't too far off.
