Circuit du Bicêtre joins Brake Point
Circuit du Bicêtre, in the Loire, is the second karting circuit added to Brake Point. 715 m, 11 corners, clockwise: full outline and turn-by-turn analysis.
Circuit du Bicêtre joins Brake Point. It is the platform’s second karting circuit after Mecamax, and the first in the Auvergne-Rhône-Alpes region. The full outline and its 11 corners are in, so kart sessions analyse there exactly as they do anywhere else.
Where it actually is
A detail that catches people out: the circuit is announced as “Montbrison” in just about every calendar, but it sits on the route de Feurs in Savigneux, the neighbouring town, in the Loire department (42) in central France. It is run by the ASK Puma Forez club.
In Brake Point it is listed under its official name, Circuit du Bicêtre.

The club lists it as category 1.2 (competition), timed by an AMB loop backed up by two Alfano strips. The 715 metres are confirmed by the Formule Promo rounds held there.
Our reference outline, traced along the centreline, comes out at 710.8 m. A few metres off the official length is normal: the official figure follows the racing line, not the middle of the track. It is consistent, and consistency is what keeps your lap distances stable from one session to the next.
Clockwise: what it changes in your data
Most circuits you ride turn left. Bicêtre turns right, and it shows up immediately in the telemetry.
On a clockwise layout, most of the work happens on the right-hand side. If you alternate between circuits, compare your left and right lateral acceleration traces: the asymmetry you find is not a flaw in the track, it is your own asymmetry that the layout exposes. This is one of the rare places where a lap time tells you nothing and the data tells you everything.
715 m, so what?
On a layout this short, a lap comes in comfortably under a minute. A tenth weighs far more than it does at Le Mans, and there is nowhere to make it back: a botched corner exit is paid for right up to the next braking point, which arrives immediately.
Eleven corners in 715 metres works out to a change of direction every 65 metres on average. The margin for error on an apex is measured in tens of centimetres, and those tens of centimetres are invisible to the naked eye. They are perfectly readable on two overlaid laps.
What is available
- Track outline on session maps, with your path overlaid
- Lap splitting on the real start/finish line crossing, in the correct direction of travel
- All 11 corners of the layout, marked on the map and used for turn-by-turn analysis
- Speed, distance, lap comparison in overlay
- BudAI coaching, with a kart profile separate from your motorcycle and car ones
Importing your sessions
A GNSS logger is all you need. The RaceBox guide and the RaceChrono guide cover the two simplest routes for karting. AiM, MoTeC and RaceLogic files import as well.
One tip for karting: use the highest GPS sample rate your logger offers. At 10 Hz over a 50-second lap you get 500 points; at 25 Hz, 1,250. On corners that follow each other every 65 metres, the difference shows up in how finely your line is resolved.
