Fast laps, tight corners and close finishes. To get good at karting, you need a lot of practice. The ultimate tool to help you during your practice sessions is the MYLAPS Kart FLEX transponder. The transponder registers lap times and counts the number of laps. It also shows race and finishing positions at events and ultimately determines the winner.

Including: holder and clip, charging cradle, AC and DC power adaptor, software and support.

How does it work?

The track you’re racing on has a MYLAPS system installed at the start and finish line and at intermediate points along the track. The system picks up the signal sent out by the transponder mounted on your kart. This signal is analyzed and lap times are measured. The system knows exactly on which lap you are and what your position is. This data is passed on to race officials and published to your personal MYLAPS account on mylaps.com.

*Ask your club or race organization if they support MYLAPS transponders.

Your personal data

Your training and event results are uploaded by the track's system or race officials. You can check, analyze and share your performance data on your personal account online. Go to mylaps.com to create a personal account and register your transponder.

Activate your subscription

Before you are able to use your new Kart FLEX transponder, you are required to activate the subscription in FLEX Manager. Please note, that the FLEX Manager software is only compatible with Windows systems. Connect the transponder to the PC by using the charger with USB connection.

Easy to set up and maintain
Your FLEX transponder is easily installed by using the holder and clip. This should be done at a maximum height of 30 cm (1 ft) above the ground. It is water resistant and shockproof and suitable for both indoor and outdoor use. FLEX transponders are rechargeable: a full charge takes approximately 16 hours. A fully charged transponder will easily get you through a race weekend: it will keep working for a minimum of 4 days. Your transponder can get a bit dirty over time. Simply clean it with a damp cloth and lukewarm water and clean the connector pins with a cotton tip.

Warranty and Insurance
Your subscription comes with warranty and insurance. It covers damage as a result of accident or fire – but not theft or loss. This means MYLAPS guarantees that the device keeps working and is in good order. We provide an unlimited warranty as long as you have an active subscription, under some conditions. Should any problems occur during normal use – as described in the manual – MYLAPS will repair or replace your transponder free of charge. See our terms and conditions for further information.
