Talaria Sting R-MX4 vs Sur-Ron Light Bee X

Ten millimetres apart on seat height, thirty on wheelbase, and $990 apart at list or $2,490 with the Sting on sale. These two are closer than any pair we have compared — and the winner changes depending on which number you care about.

The short answer

Consider the Sting R-MX4 if you want the most torque at the rear wheel for the least money. It is $990 cheaper, carries 27 per cent more wheel torque, runs a full 19in wheel at both ends and claims a higher top speed.

The Light Bee X is the one to look at if you want the lighter bike with more peak power and a published suspension specification. It is 7 kg lighter, makes 2 kW more, and charges from 20 to 80 per cent in two hours.

Neither can be registered in Australia. Both are trail and track bikes, and on paper they are close enough that the decision comes down to which of those two lists sounds more like your riding.

Price check, 16 September 2026. A e-Bikes, Talaria’s Australian and New Zealand distributor, currently has the Sting R-MX4 discounted to $5,000 from its $6,500 RRP. Against the Light Bee X at $7,490 that is a $2,490 gap on the day rather than the $990 the list prices suggest. Sale pricing moves, so the RRP comparison is the durable one.

Power and torque pull in opposite directions

This is the part that confuses people. The Light Bee X makes more peak power — 10 kW against 8 kW. The Sting R-MX4 puts more torque to the rear wheel — 376 Nm against 295 Nm, which is 27 per cent more. Both figures are correct, and they are not in conflict.

The difference is gearing. Talaria quotes the Sting’s 376 Nm at its standard 44T sprocket, and the bike’s stated 8.35 gear ratio is the ratio at that sprocket. It trades outright power for multiplication at the wheel. In practice that favours the Sting where you are clawing up something steep, and favours the Light Bee where the ground opens up and you want the top end.

One caution before you compare these numbers against a dealer listing. The Light Bee X’s current figures are 10 kW and 295 Nm. A good deal of material still in circulation quotes 8 kW and 266 Nm, which is the previous model year — and 8 kW happens to be exactly what the Sting makes. It is an easy way to conclude the two bikes are level on power when the current models are not.

Weight, and what 7 kg actually means

59 kg against 66 kg is a 12 per cent difference, and it is the clearest practical gap between them. It is felt picking the bike up after a fall, turning it around on a narrow trail, and lifting it into a ute — the situations where a bike this size earns its keep. Neither is heavy by any absolute standard, but the Light Bee X is the easier one to throw around.

Same size, different wheels

Dimensionally there is almost nothing in it. Ten millimetres of seat height, thirty of wheelbase, ten of ground clearance. Two riders swapping between them would not describe them as different-sized bikes.

The wheels are the exception. The Sting runs 19in front and rear; the Light Bee X runs 19in front and 18in rear. On full-size petrol bikes a 19in rear is the motocross standard and an 18in the enduro standard, chosen for a taller sidewall over rocks — but both of those run a 21in front, and neither of these does. These are small-wheel platforms, and their rears are narrow sections rather than the 110/90-19 a motocrosser wears. Both are well served for rubber: Dunlop, Bridgestone, Mitas, Maxxis and Kenda all make off-road tyres that fit this class.

What we cannot tell you about the Sting

Talaria does not publish suspension travel for the Sting R-MX4. Sur-Ron publishes the Light Bee X’s in full: a fully adjustable KKE inverted fork with 200 mm of travel, and a KKE single rear shock with 210 mm.

On a pair of bikes this close, suspension could reasonably be the thing that separates them, and we would rather say plainly that the figure is not available than publish one we cannot stand behind. If Talaria or its Australian distributor publishes it, we will add it.

Neither one can be registered

Both are off-road only. Neither is homologated in Australia, so both are restricted to private property, gazetted areas and ride parks, and where you can legally ride an unregistered bike varies by state — our ride spot directory covers the rules state by state.

If registration is what you actually need, neither of these is the bike, and the comparison to read instead is the Light Bee X against the Ultra Bee HP, which is ADR compliant.
