Before you ride: the sim
We model your bike, gearing and the track geometry to build a model-estimate lap, a POV ghost video and a gearing study before you turn a wheel. Sim outputs are estimates, not targets.

Not a timing sheet.The whole picture of your lap.
LeanLine Labs puts your bike data, lean and line, optional heart rate, helmet notes and the track itself on one timeline. A physics lap sim then helps explain why a lap is slow and what you could change.

The sequence
How it works
On track: log what you already use
Bike data (throttle, RPM, gear, speed) from a logger such as the AiM Solo 2 DL; lean angle and GPS line from a RaceBox; optional heart rate from a compatible watch such as Garmin; helmet voice notes and engine audio (planned).
Session drift check first
Before corner suggestions, the debrief looks at your lap data, and heart rate if you choose to share it, for a drift pattern, such as lap times rising late in a session. If it finds one, corner suggestions pause and it suggests a break, water and a shorter next session. It can't tell whether you are fit to ride; you decide that.
Then corners and setup
When no drift pattern is flagged, the track model, your bike data and the sim inform technique and setup suggestions.

Sim and gearing study
Physics lap sim for your bike and track: model-estimate lap, POV ghost video, gearing study.
Planned launch: 2027Session debrief
Your logger, GPS and optional heart-rate data, plus audio (planned), on one timeline; a session drift check, then corner and setup suggestions.
Planned launch: 2027What you bring
- Optional: a data logger such as the AiM Solo 2 DL, a RaceBox, a compatible heart-rate watch (for example Garmin), a helmet mic. Use only devices your track-day organizer allows.
- Track-ready bike that passes tech inspection
Safety first: our suggestions never push for more speed or more lean. You decide how you ride.

About LeanLine Labs
LeanLine Labs is a motorcycle track-day data and lap-sim company based in League City, Texas. We built it to put the track's geometry, the bike's data and the rider's own session data in one place.
We combine a physics lap sim, rider and bike data to help explain why a lap is slow and what you could change. We are starting with Texas tracks; launch is planned for 2027.
