Street bike on track: what tech inspection checks
Before your road bike goes out at a track day, it has to pass tech. US organisers publish the rules: tape, tyres, coolant and safety wire.

Tech comes before the first session
At a track day, every bike goes through technical inspection before the organisers allow it on track. Sportbike Track Time (STT) and Fast Line Track Days both say a bike that fails tech gets no refund, and that preparing the bike is the rider's job. The rules below come from their published lists. Other organisers differ, so check yours before the day.
Tyres, tape and cameras
Tyres and brakes must be in good condition. Both organisers want tyres at 50% or more of new, and tyres turning blue from wear are refused. Headlight, indicators, glass and plastic lenses must be taped over or removed. The number plate must come off or have its bolts taped.
The bike needs a working kill switch on the handlebar and a throttle that closes by itself. Every valve stem needs a cap, and wheel balance weights must be secure and taped over. Cameras on the bike must be tethered. STT bans helmet cameras, and Fast Line bans helmet and chest mounts.
TrackDNA explains why the tape matters: if you crash, broken lights scatter debris, and tape keeps the pieces together. That means less clean-up and less chance of a red flag. Its pre-tech list also includes brake pads with at least half their life left, no oil or coolant leaks, and a chain that is clean, lubed and adjusted.
Mirrors and stands
STT requires mirrors to be removed in the Advanced group and at least taped in the others. Fast Line asks for them to be removed in all groups if possible.
STT recommends removing a centre stand and does not allow one in Advanced, because of ground clearance. Fast Line does not allow centre stands at all. It recommends removing or safety-wiring the side stand, and otherwise the side stand kill switch must work.
Coolant and safety wire for faster groups
In Intermediate and Advanced, both organisers allow only water, Water Wetter or a coolant that is not based on ethylene glycol. Their approved brands are Evans, 7th Gear, Liquid Performance and Engine Ice. Automotive ethylene glycol coolant is not allowed.
The oil drain plug, oil filter and filler cap must be safety-wired. STT asks for this only in Advanced and accepts a dab of RTV or silicone in Intermediate. Fast Line requires wire in both groups. It won't move a Novice up until the bike is wired and the coolant has been changed, and it bans external K&N oil filters in every group. STT notes that if you spill oil on the track, your day is over.
