Alfano Legend — Best for Simplicity
The Alfano Legend is the evolution of the Alfano V2 — the unit that dominated karting in the late 90s and early 2000s. It is 100% plug and play: attach it to your kart and drive. No configuration required.
The Legend uses 25Hz GPS for automatic track recognition and beacon-free lap timing. It has one temperature input (H2O, CHT, or EGT), Bluetooth and NFC data transfer, and outstanding battery life. It does not have Bluetooth 5.0 or wireless peripheral sensor connectivity.
Best for: Club racers, arrive-and-drive drivers, and anyone who wants accurate GPS lap timing without complexity.
Alfano 7 1T — Best Entry-Level Data Logger
The Alfano 7 1T adds Bluetooth 5.0 data transfer and wireless/IR peripheral connectivity over the Legend — meaning it can pair wirelessly with the Alfano TyreControl Junior 2 tyre pressure gauge without cables. One temperature input monitors water temp or EGT.
Best for: Club and recreational kart racers who want GPS lap timing, single-channel temperature data, and wireless tyre pressure monitoring.
Alfano 7 2T — Best All-Round Kart Data Logger
The Alfano 7 2T is our top recommendation for serious and competitive kart racers. Two temperature inputs let you monitor CHT and EGT simultaneously. Option 5 (A1084) includes both a water temp sensor and K-type EGT sensor — the ideal Rotax package. Wireless/IR peripheral connectivity pairs with the TyreControl Junior 2 without cables.
Best for: Competitive club racers, Rotax, KZ, and anyone who wants full engine data and wireless tyre pressure monitoring in one system.
AiM MyChron 6 2T — Best for AiM Ecosystem Users
The AiM MyChron 6 2T is a strong dual-temperature GPS kart data logger with Wi-Fi data transfer and AiM Race Studio 3 analysis software. It is the natural choice for drivers already using AiM products or planning to move into circuit racing with AiM dash loggers. It does not have wireless peripheral sensor connectivity.
Best for: Drivers already in the AiM ecosystem, or those who want the most advanced PC data analysis tools.
Our Verdict
For most NZ kart racers, the Alfano 7 2T is the best GPS kart lap timer. The wireless tyre pressure integration, dual temperature inputs, and Bluetooth 5.0 data transfer make it the strongest all-round package at this price point.
If you want simplicity above all else, the Alfano Legend is hard to beat. If you’re already in the AiM ecosystem, the MyChron 6 2T is the logical choice.
