For storage - I do keep this tail bag on for storage.

When not in use - it is small and not in the way. I did purchase a removable tail box trunk but have used it yet.
As far as Lifan vs Hawk - I can tell you I am very happy with the Lifan. From all I have read on the forum - the Lifan Xpect is considered a higher end china bike. I purchased it specifically because it has EFI.
Have you read thru the Hawk 250 Resource thread pinned to the top of the Dual Sport/Enduro forum?
