10 jars of spices and the motorcycle. Selected properly and in big enough jars, I could become a very rich man selling those spices.

The bike I'd have an artisan painstakingly disassemble while documenting it for recreation.

It's bound to have a battery, lights, alternator, and some semiconductors. Use them to bootstrap electronics.

The engine could be retrofitted to run off alcohol, or use it with steam. Don't know how possible that is.

The springs would make for killer crossbows. Tire rubber, too.

Really, the motorbike is a mountain of treasure.
