Free to download. Membership is optional and priced by your store, in your currency.

The AI Mechanic

Ask anything about your bike. It knows what you ride, what you’ve already serviced, and the conditions where you ride.

  • Diagnostics, codes, maintenance schedules, oils and filters, in plain words
  • Members: answers grounded in the official Harley service manual for your exact platform and year, with page references you can check
  • When the bike needs hands-on work and a partner garage is listed near you, it drafts a booking with the diagnosis attached
From your workshop’s store

Where the workshop you use has connected its parts store, the AI can suggest parts from it that fit your bike. It never invents a part number or a price.

Ask anything about your bike: diagnostics, codes, maintenance schedules, what oil to use, when the air filter is due. The AI knows what bike you ride (you told it once), what you’ve already serviced, and the conditions where you ride.

Free riders get answers from the model's general training — solid for day-to-day questions. Members get answers grounded in the official Harley service manual for their exact platform and year, with quote-and-cite page references they can verify themselves.

When the AI's diagnosis says the bike needs hands-on attention, it can draft a booking on your behalf — pre-filled with the diagnosis summary so the workshop knows what's coming.

Rides & routes

Plan group rides, record your own, save the routes you love, and keep up with the riders you follow.

  • Group rides with a meeting point and route; RSVP and see who’s going
  • Record by GPS, even with the screen off: route map, distance, moving time, speeds
  • Save routes: pin stops on a map, import a GPX file, or turn a recorded ride into a route

Plan group rides with a meeting point and route, RSVP, and see who's going. Record your own rides by GPS — even with the screen off — and save them as activities with the route map, distance, moving time, and speeds. Followers give kudos and comment.

Follow other riders (and find them by the bike they ride), keep up on the feed, and broadcast your live pulse so people can watch a ride in real time. Post to the Wall — used parts, mod showcases, route shares — join crews, and message riders directly. Members also get a ride weather forecast with prep tips before each ride.

Events

Ride-outs, meetups, shows and track days on one calendar.

  • See what’s on near you and add it to your phone’s calendar
  • Know of an event? Submit it; the team reviews each one before it’s listed
  • Share an event: the link opens it in the app, or on forty5d.com for friends without it

A garage that knows your history

Every service, every kilometre, every consumable on the bike’s record.

  • The AI and the workshop both see what was done and when
  • Log mileage in seconds, or snap the odometer and the app reads it: no adapter needed
  • Sold the bike? Transfer it to the new owner with its full history
Read more: A garage that knows your history

Every service, every kilometre logged, every consumable replacement is on the bike's record. The next time you ask the AI Mechanic about brake pads, it already knows when they were last done. The next time you book an oil change, the workshop already knows the Twin Cam 103 spec for your bike.

Sold the bike? Transfer it to the new owner with full service history attached — they get the value of the historical record, you keep your account.

Questions

Frequently asked

Where do I get the app?
On the App Store and Google Play. Forty5° is free to download.
Which bikes are supported?
Forty5° is built around American iron — Harley-Davidson especially. Member diagnostics are grounded in the official Harley service manual for your exact platform and year, and you can register any bike in your garage.
Does it work where I ride?
Ride planning, ride recording, your garage, and the AI Mechanic work wherever you ride. Workshop booking connects you to the workshops listed in the app near you.
Do I need an OBD adapter?
No — the app works fully without any adapter. You log your mileage in seconds, or snap a photo of your odometer and the app reads it for you.
What’s free and what’s paid?
The app is free to download and free to use. A paid Member subscription adds manual-grounded AI Mechanic answers, error-code look-up, a higher daily question allowance, ride weather, a longer maintenance forecast and your service history as a PDF. Any introductory offer is shown in your store, and you can cancel any time from the App Store or Google Play.
What happens to my data if I stop paying?
Cancelling ends auto-renew — you keep Member access until the end of the period you've already paid for, then the account moves to the free tier. For exactly how your data is handled, see our Privacy Policy.
