Are you talking about the Tarjeta de Turismo you paid $20 for? Or are you talking about your vehicle import permit that you paid $37 for?
The Tarjeta is totally not a problem....in fact you don't even need one in Baja unless you: Go south of Guerrero Negro and stay longer than 7 days. I've made many Baja trips never buying the Tourist card (going around the checkpoint in the dirt. On the mainland you may be asked for it at checkpoints.
The bike is another matter. You should have a vehicle import permit and with it a Turista sticker for your bike....but don't put it on....someone will steal it, just keep it with you.
You only need the vehicle permit if you're going to mainland Mex on Ferry or by land. Sonora state (like Baja) is exempt, which almost no one knows.
So the final destination means nothing. Don't worry.
