StemmaPass

The service book for a track motorcycle

A track bike goes through consumables far faster than a car, and its history matters just as much when you sell. StemmaPass follows chain, fork, brake fluid and tyres in miles and track hours, from your workshop invoices, and produces the public link you hand to the buyer.

Two demo bikes, running the real wear engine

No account, nothing to install. Add track sessions and watch the gauges move: these are the same calculations the app runs.

What is different from a car

  • Its own service life, not car numbers reused

    The wear engine counts a set of tyres as two to four track days, where a car gets ten. Pads, brake fluid and engine oil have their own figures too.

  • Parts a car does not have

    Chain and sprocket, fork oil, valve clearance: the motorcycle catalogue is separate, with its own part numbers — DID, AFAM, Öhlins, Motul — and its own intervals.

  • Track hours as much as mileage

    An odometer says nothing about a day on track. Wear is counted on both axes, and importing a GPS file fills in the second one without any typing.
