The F2R roadbook has a handy little area inside the transmission area to keep your spare drive belt and cover strap.

The left zip tie is holding a drive belt. The right zip tie is holding the "spare lock" (a.k.a. cover strap). I left the "spare lock" in the bag so that I would know which is which. Gently fasten the zip ties so you don't pinch the belts.

This solution should keep them close at hand and protected from the elements until they are needed.

Rally on!
