Your Race Ninja, your way
Race Ninja is your platform, so now it can look like yours. Pick a brand colour in your profile and the whole site wears it, from your dashboard to your lap charts.
Your kart fades near the end of a session. Now you can see exactly why
Your kart is rarely as fast on lap 12 as it was on lap 3. Race Ninja's new lap-by-lap performance graph shows whether it's the engine, the tyres or the track losing grip, so you can stop guessing and start tuning.
Your track's not on the list? Add it yourself, free
Race at a track we don't have yet? Add it yourself from your GoPro or DJI footage, no logger required, and your first analysis is free.
Free kart analysis, no data logger and no catch
Kart telemetry doesn't have to start with a few-hundred-quid receipt. Get a free analysis every month, more when you add tracks or share a session, all from your GoPro or DJI footage.

Daytona DMAX, Sodi and N35 just became race classes on Race Ninja. If you race Daytona's karts, your fastest verified lap can now go on the leaderboard for your track and class.
Find the lap time hiding in your corners

Every track has a champion now. Think it should be you?
Track Champions are live: the fastest verified lap in every class, on every track page, straight from onboard footage. Your footage stays private. Your time goes public.
GoPro Hero 11 GPS for racing: the value pick for telemetry
If you want one camera for racing telemetry without spending a lot, the GoPro Hero 11 Black is hard to beat. It has GPS, the data it records is genuinely good, and now that it's a couple of models old you can find it cheap. What GPS the Hero 11 has The Hero 11 introduced a newer...
Does the GoPro Hero 12 have GPS? (and what to do about it)
Straight answer: no. The GoPro Hero 12 Black has no GPS. And unlike a setting you forgot to switch on, there's nothing you can do about it. GoPro took the hardware out. This catches a lot of racers off guard. You upgrade from a Hero 11 expecting more of everything, and your telem...
