Fast riders don't just ride. They analyze.

"It's actually quite of a game changer." – Maxime Renaux

Welcome to the Crossbox family.

Together, we're bringing data-driven motocross training to the next level.

Crossbox' motion sensors detects all jumps you do on the track.

Train smarter with heart rate data.

Crossbox and the CBX devices are compatible with all major HRM chest straps.

Data. Racing. Development.

Behind the scenes with Mokadamo as we bring Crossbox into the karting world.

From live lap timing to detailed post-session analysis — this is only the beginning.

The new iOS major update is available now.
More precision. More insight. More performance.

What’s new:

• Introducing Delta Time Analysis: pinpoint exactly where you gain or lose time
• Live lap timing rebuilt from the ground up — faster, smarter, more detailed
• Live delta time now visible during lap tracking
• Now compatible with RaceBox Mini, Mini S and Micro
• Export sessions in multiple raw data formats
• Redesigned tracks menu + improved stability
• With this update you can now create a new track also if your GPS tracker doesn't support to record sessions (RaceBox Mini)
• Various fixes and performance improvements

We’ve just released a major update for CROSSBOX Lap Timing (for iOS - Android update is coming soon), completely reworked app (fixed many bugs) now fully optimized for RaceBox Mini, Mini S & Micro.

Crossbox is a well-known brand in the Motocross community, but over time it’s been picked up more and more in car racing, karting, downhill MTB and other racing disciplines — so this update is focused on making it a solid, reliable tool across all of them.

What you can expect:

• Very high lap time accuracy – extensive work on smoothing & interpolation brings results down to ~0.01–0.02s
• Professional analysis, simple to use – clear data without unnecessary complexity
• Cloud-based storage – all sessions are securely stored on our servers and always accessible
• Driver connection – add others, compare laps and performance directly
• Track leaderboards – see how you rank on each track
• Live lap timing & delta – use your phone as a real-time display or review sessions afterwards
• AI-assisted Pro-Analysis – quickly identify where time is gained or lost
• Lap playback – analyze laps in detail

There’s a 14-day free trial, so you can try everything on track without commitment. After that, the app costs €29,99/6months.

Feedback from the community is always appreciated!

We tested 49, 50 and 51 tooth sprockets on a 125cc.

The result: very similar lap times.

But looking deeper, small differences can still show up —
especially in how the bike drives out of corners.

250 two-stroke vs. 450 four-stroke

Same rider — over 2 seconds difference. The 450 was faster.

The data shows why:
especially in tight corners, more speed from mid-corner to exit and stronger drive.
