Navigation app that allows me to plan my own route

I am about to fulfill an old dream of mine to buy a Vespa 300GTS.
While this motorbike can go on the highway its something I want o to avoid as much as possible. When I use the Maps app on my iPhone for navigation it only gives me a couple of options.

I am looking for a navigation app that allows me to select and save my own route in advance.

Any suggestions?

Sounds like a lot of fun. The first motorbike I ever rode was my cousin’s Vespa. His was sold by Sears around 1960 under the Allstate name. Here’s an app I hear about that works with Apple Maps to plan multi-stop journeys. Thought it might be worth a look:

Strava is fitness-oriented but lets you plan and save routes.
