MyLaps TR2 Car, Bike, Offroad Transponder

MyLaps TR2 Transponder — Car, Bike & Offroad

The MyLaps TR2 is the current-generation rechargeable transponder for circuit racing, motocross, superkart, offroad, and buggy racing in New Zealand. If your club or series uses MyLaps timing — and the vast majority of MSNZ-affiliated circuits do — this is the transponder your class requires. Accurate to the millisecond, IP67 waterproof, and managed entirely through the Speedhive app on your phone.

Harris Race Radios is an authorised MyLaps dealer for New Zealand, supplying genuine MyLaps transponders direct through the official MyLaps supply chain. When you buy from us, you're buying the real thing with full warranty support — not a grey import.

What Is a Transponder and Why Do You Need One?

A transponder is a small electronic device mounted to your race vehicle that communicates with timing loops embedded in the track surface. Every time you cross a loop, the system records your passage to the millisecond — generating your lap times, race results, and sector splits that appear in your Speedhive account and on the official results sheet. Without a transponder, your laps cannot be officially timed and you cannot be classified in results. Most MSNZ-affiliated circuits and club days require competitors to carry their own transponder.

Specifications

Installation

Mount the TR2 transponder as vertically as possible on your vehicle, no more than 60 cm above the ground. Use the TR2 Holder (available separately) for a secure, repeatable mount. For motocross and offroad applications, ensure the transponder is protected from direct impact and mud ingress — the IP67 rating handles water and dust, but the unit should not be mounted in a position where it can be struck by debris or other vehicles.

Subscription Information

MyLaps TR2 transponders require an active subscription to function at timed events. Subscriptions are purchased and renewed through the Speedhive app. The unlimited warranty on the TR2 is only valid while a subscription is active — if your subscription lapses, the warranty reverts to standard terms.

Common Mistakes When Buying a MyLaps Transponder

• Buying the wrong variant. The TR2 Car/Bike/Offroad is not interchangeable with the TR2 Speedway or TR2 Kart. Check with your club timekeeper before ordering if you're unsure which system your track runs.
• Forgetting to budget for a subscription. The transponder purchase does not include a subscription. Factor in the cost of a 2-year or 5-year subscription when comparing prices.
• Buying second-hand without checking subscription status. A second-hand TR2 with a lapsed subscription loses its unlimited warranty. Always verify subscription status before buying used.
• Mounting too high. The TR2 must be mounted no more than 60 cm above the ground. Mounting higher than this will result in missed reads at the timing loop.
• Not registering the transponder before race day. Register your unit in the Speedhive app and confirm your transponder ID with your club timekeeper before your first event — not on the morning of.
• Choosing rechargeable when a permanent install suits better. If your car has a 12V battery and you never move the transponder between vehicles, the TR2 Direct Power eliminates charging entirely.

Frequently Asked Questions

Is this the right transponder for MSNZ circuit racing?

Yes — the MyLaps TR2 Car, Bike & Offroad transponder is the correct unit for MSNZ-affiliated circuit racing in New Zealand. If your series or club specifies a particular transponder type, confirm with your club secretary or timekeeper before purchasing. Contact Aaron Harris if you're unsure.

Do I need a subscription to use this transponder?

Yes — MyLaps TR2 transponders require an active subscription to function at timed events. Subscriptions are purchased and managed through the Speedhive app. The unlimited warranty on the TR2 is only valid while a subscription is active. See our full subscription guide →

Can I use this transponder for both circuit racing and motocross?

Yes — the TR2 Car, Bike & Offroad transponder covers circuit racing, motocross, superkart, offroad, and buggy racing. It is not the correct unit for speedway or kart racing — those disciplines require their own specific TR2 variants.

What's the difference between the TR2 rechargeable and the TR2 Direct Power?

The standard TR2 is rechargeable via USB and runs on its internal battery. The TR2 Direct Power is hardwired directly to your vehicle's 12V battery — it cannot be used as a rechargeable unit. Direct Power suits competitors who want a permanently installed transponder that never needs charging. The rechargeable TR2 is more flexible if you race multiple vehicles or want to remove the transponder between events.

Can I move the transponder between different vehicles?

Yes — the TR2 transponder is registered to your MyLaps account, not to a specific vehicle. You can move it between vehicles as needed, provided it is correctly mounted and within the 60 cm height limit at each installation.

Do you hold NZ stock?

Yes — Harris Race Radios holds NZ stock sourced directly through the MyLaps supply chain, for fast local dispatch. No waiting on international freight for your next race weekend.
