Quick Reference — Which TR2 Do I Need?
| Racing discipline or installation | Relevant transponder listing |
|---|---|
| Speedway oval racing | TR2 Speedway |
| Car circuit racing, superkart and offroad where this model is specified | TR2 Car, Bike & Offroad |
| Road and circuit motorcycle racing | Check your series requirement for TR2 Motorbike or Car/Bike |
| Motocross and relevant enduro/trail events | TR2 MX Bike |
| Kart racing | TR2 Kart |
| Hardwired car/bike installation | TR2 Direct Power Car/Bike |
| Hardwired Speedway installation | TR2 Direct Power Speedway |
TR2 Speedway vs Car/Bike/Offroad
The TR2 Speedway listing serves speedway competitors, including saloon cars, stock cars and midgets. The TR2 Car, Bike & Offroad listing covers the circuit and offroad applications stated on that product. Confirm the actual specification with your club or timekeeper rather than choosing solely from the track shape or product name.
The rechargeable Speedway unit is listed with up to five days' battery operation, IP67 housing and Speedhive management. Use the individual product specifications for the unit you are ordering.
TR2 Kart vs Car
For kart racing, start with the TR2 Kart transponder and your kart club's requirements. Do not assume a Car/Bike unit is suitable for every kart application. Superkart competitors should confirm their series specification. Follow the mounting instructions for the exact unit.
TR2 MX vs Motorbike
The TR2 MX Bike is the listing to check for motocross and relevant enduro or trail events using MyLaps timing. The TR2 Motorbike listing addresses road and circuit motorcycle racing. MyLaps distinguishes bike and MX applications; a road-bike unit should not be assumed suitable for motocross.
Rechargeable vs Direct Power
| Question | Rechargeable TR2 | TR2 Direct Power |
|---|---|---|
| Power source | Internal rechargeable battery; use the appropriate cradle and cable | Correctly installed switchable vehicle 12V supply |
| Installation choice | A removable unit, with charging maintained before racing | A suitable hardwired installation in a dedicated vehicle |
| Preparation | Check charge, mounting and activation | Check vehicle power, mounting and activation |
| Subscription-based TR2 setup | Speedhive connection using a powered cradle | Speedhive connection with the installed unit in Bluetooth mode |
Direct Power removes the need to recharge the transponder's internal battery. It does not eliminate registration or subscription activation. Compare the Direct Power Car/Bike and Direct Power Speedway listings. Keep the Direct Power manual for installation.
TR2 vs TR2 Go — What's the Difference?
A subscription-based TR2 has a time-limited entitlement that must stay current. TR2 Go is the no-recurring-subscription alternative. Compare the actual options on the chosen product rather than assuming Go is a renewable plan or automatically the cheaper purchase.
| Option | Subscription-based TR2 | TR2 Go |
|---|---|---|
| Recurring subscription | Required | Not required for the Go option |
| Manufacturer warranty | Cover during an active subscription, subject to warranty conditions | Standard two-year warranty |
| What to compare | Included term and renewal requirements | Upfront cost and no-recurring-subscription entitlement |
Warranty is not an unconditional promise to replace every failure or type of damage. Detailed activation, renewal, synchronisation and expiry help belongs in the TR2 Subscription Guide.
Accessories
