Supermoto on the kart track - gearing, geometry and backing it in
Gearing first
Kart tracks are 1st-3rd gear territory. Go +2 (tight) to +4 (very tight) teeth on the rear vs your baseline so 2nd gear carries the slowest corner - lugging 1st kills drive and control. Fast layout days: back to baseline or -2. (LAISA encodes tight = +2 rear for supermoto.)
Geometry for flick speed
More fork protrusion through the clamps (+2 to +5 mm, front lower) quickens steering for the chicane-dense layout; give it back on fast tracks.
The WP shortcut
KTM/Husqvarna publish three click maps in the manual - comfort (17), standard (12), sport (7). Kart-track novice: start at standard, NOT sport; the stiff map punishes you on tight bumpy kart tarmac.
Backing it in (the setup share of a technique skill)
The setup that makes sliding learnable
- Fork compression OPEN (several clicks out): you WANT dive - the front loads, the rear goes light.
- Forks slightly higher through the clamps (front lower still).
- Rear rebound OPEN +1-2 clicks: the shock must extend quickly on corner entry so the rear "hovers". Too much rebound damping pins the rear and it grips instead of sliding.
- Rear tire pressure +0.2 bar: deliberately less rear grip.
- Slipper clutch setting and rear brake use are TECHNIQUE, not clickers - learn them on a wet or dirt patch first. This is exactly what LAISA's supermoto aggressive style preset applies - note it INVERTS the road-racing aggressive logic (stiffer everywhere) on purpose.
Day rhythm
Pressure check between sessions (small tires heat fast), sag stays at ~80 mm rider sag (SMR factory target), and the track gets greasy with kart rubber by afternoon - one click softer compression usually buys back the grip.
