TALARIA STING MX5 PRO

The Talaria MX5 is the most powerful bike Talaria has built on the Sting platform, and the Sting MX5 Pro is the version most UK riders are asking us about. It moves the whole design up to a 72V 40Ah battery, adds a reinforced gearbox, larger brakes and a colour TFT display, and it is available from us as an off road machine or in a road legal specification. This guide explains what changed, what the figures mean on a real trail, and who the Talaria MX5 suits.

What the Talaria MX5 changes

Every earlier Sting ran a 60V system. The Talaria MX5 Pro moves to 72V, and that single decision touches almost everything else on the bike. Talaria quotes a 45 percent power increase over the 60V models, and to carry that power reliably the factory redesigned the gearbox, thickened the brake discs, fitted larger four piston calipers and moved to a heavier 428 chain. The frame is still the forged 6061 aluminium Sting chassis, so the compact feel that made the Sting popular has not been lost.

A quick orientation for new buyers

The Sting MX3 was the original, the Sting R MX4 refined it, and the MX5 Pro is the current top of the family. Sting Pro, MX5 Pro and TL5500 all refer to this same bike. When people search for a Talaria Sting Pro they are almost always looking at the MX5 platform.

Two versions from one platform

We list the Talaria MX5 in two configurations. The off road version is the pure trail and track bike with no lighting homologation, intended for private land and organised venues. The road legal version carries the additional equipment needed for registration. Both share the same battery, motor, gearbox, brakes and suspension. If you want a Sting for the road, our road legal Talaria category explains the licence categories in detail.

The 72V battery and the numbers behind it

The battery is a 72V 40Ah pack built from Samsung 50S 21700 cells, giving 2,880 watt hours of stored energy. That is the figure to hold on to when comparing bikes, because watt hours describe how much work the pack can do regardless of voltage. A typical 60V 38.4Ah Sting pack stores roughly 2,300 watt hours, so the Talaria MX5 carries around a quarter more energy while also delivering it at a higher voltage.

Rated and peak power

The Talaria MX5 motor is listed at 5.5 kW rated and 13.4 kW peak when unrestricted. The motor is an interior permanent magnet unit, mid mounted and air cooled, driving through a sealed gearbox to a 428 chain and 48 tooth rear sprocket. Rear wheel torque is quoted at 500 Nm with that sprocket. Those figures are why the front wheel lifts from a standstill in Hyper mode.

Range in the real world

The official maximum range is 100 km at a steady 25 km/h, which is 62 miles at 15 mph. Nobody rides a dirt bike like that, and we would rather set expectations honestly. Hard trail riding with a heavy throttle hand in Sport or Hyper will use energy far faster than the headline number suggests. Terrain, rider weight, tyre pressure and ambient temperature all matter, and the pack is removable with a handle, so a charged spare turns a morning into a full day.

Chassis, suspension and brakes

The Talaria MX5 frame is forged from 6061 aluminium under 6,000 tonnes of press force and then anodised. Net weight is 76 kg with the battery fitted, wheelbase is 1,250 mm, seat height is 840 mm and ground clearance is 300 mm. The maximum recommended load is 100 kg and the quoted maximum climbing angle is 45 degrees.

Suspension tuned for the extra power

Up front is an adjustable air and dual spring fork with 220 mm of travel. At the rear, a linkage driven shock with 85 mm of stroke controls the swingarm. Talaria revised the settings for the MX5 rather than carrying over the MX4 setup, and the result is a bike that stays composed when the extra torque loads the rear on exit from a corner.

Braking that matches the speed

The Talaria MX5 runs hydraulic four piston calipers at both ends acting on 220 mm discs that are 3 mm thick. The thicker disc is not a cosmetic choice: it holds more heat before fading, which matters on long descents. The master cylinders were redesigned and the system runs DOT fluid. Add the regenerative brake lever and you have three ways to slow the bike, which is reassuring on wet chalk or loose shale.

Wheels and tyres

Wheels are 19 inch front and rear with 1.4 and 1.6 inch rim widths, laced with straight pull reinforced spokes to CNC machined hubs. Tyres are 70/100 section front and 80/100 rear on the 19 inch rims, an off road pattern as standard. Footpegs are CNC machined and anodised black, and the headlight has its own switch so you can run dark on the trail and save energy.

Riding modes, Hyper and regenerative braking

Three modes are available from the bars: Eco, Sport and Hyper. Eco softens the throttle and extends range for tight woodland or a newer rider. Sport is the everyday setting with full torque but a progressive map. Hyper unlocks the full output and is unique to the MX5 Pro within the Sting family. Talaria mx5 top speed figures quoted online almost always refer to Hyper mode on an unrestricted bike.

What Hyper mode actually feels like

The throttle becomes immediate and the front wheel wants to leave the ground under a firm hand. Expect to move your weight forward and to feed the throttle rather than snap it open. Riders coming from a 60V bike usually spend their first hour in Sport and switch to Hyper once the track opens up.

Four levels of regeneration

Regenerative braking on the Talaria MX5 is adjustable across four levels and there is a dedicated regen lever on the bars. On a long descent you can set a high level and ride the motor like engine braking on a petrol bike, saving your pads and putting a little energy back into the pack. On slippery ground a lower level keeps the rear from stepping out when you shut the throttle.

Speed limit out of the crate

The Talaria MX5 is factory limited to 32 km/h, which is 20 mph, when it leaves the crate. Unrestricted performance is available for off road use on private land, and we go through the process at handover. Our post on Talaria MX5 top speed covers what to expect in each mode and why the numbers vary between riders.

These are the manufacturer figures for the Talaria MX5 Pro. Where a number depends on rider weight or terrain we say so rather than pretending it is fixed.

MX5 Pro versus the Sting R MX4

The Talaria Sting R MX4 remains an excellent bike and for many riders it is the sensible choice. It is lighter, it costs less to buy and to insure for the road legal version, and its 60V system is easy to live with. The Talaria MX5 is for the rider who has found the ceiling of a 60V bike and wants more of everything without stepping up to a much larger and heavier machine.

Where the MX5 pulls ahead

• Peak output of 13.4 kW against the 60V bikes, with the Hyper mode that only the Sting Pro MX5 has.
• A 2,880 Wh pack that runs at 72V, so more energy and less voltage sag under load.
• 220 mm discs at 3 mm thickness with larger calipers, which the MX4 does not have.
• A 428 chain and reinforced gearbox designed around the higher torque.
• A colour TFT display and a regen lever as standard.

Where the MX4 still makes sense

• Lower weight, which matters on tight single track and when lifting the bike into a van.
• A large parts ecosystem and a longer track record of ownership in the UK.
• A gentler power delivery that suits younger or newer riders.

We compare the two head to head in Talaria Sting R vs MX5, including which one we would pick for green lanes on a road legal version and which for a private motocross track.

Where you can ride it in the UK

The off road Talaria MX5 cannot be used on any public road, byway, bridleway, footpath or pavement in the UK. It is for private land with the landowner’s permission, for practice tracks and for organised events. That is not a grey area and we would rather you hear it clearly from us than from a police officer. The Auto Cycle Union is the governing body for off road competition and its clubs run venues across the country where a bike like this belongs.

The road legal route

If you want to ride to the trail rather than trailer to it, the road legal Talaria MX5 Pro is the answer. It is registered as an L category vehicle under the framework in Regulation 168/2013, which means registration, a number plate, insurance, a compliant helmet and the right licence for its class. Our guide to whether Talarias are legal in the UK lays out each class in plain English.

Green lanes

Green lanes, properly called byways open to all traffic, are public roads and need a registered, insured, road legal bike. The Trail Riders Fellowship publishes guidance on lawful routes and responsible riding.

Ownership, charging and upgrade paths

Living with a Talaria MX5 is simpler than living with a two stroke. There is no fuel, no clutch, no air filter soaked in oil and no valve clearances to check, but there are a few habits that keep the battery, gearbox and chain healthy for years, and they take minutes each.

Charging, oil and chain

Charge the Talaria MX5 in a dry place on a hard floor, let the pack cool after a hard ride before plugging in, and avoid storing it flat or at full charge for weeks on end. Around half charge is the kindest state for a lithium pack sitting through winter. The sealed gearbox uses oil that should be checked and changed on schedule, and the 428 chain wants cleaning, lubricating and correct tension like any motorcycle chain.

Upgrades when you are ready

The Talaria MX5 Pro is quick as delivered, and we would suggest riding it in standard form for a full season before changing anything. For riders who then want more, the platform accepts uprated controllers and higher voltage packs, and our two Competizione builds show how far the chassis can go.

Frequently asked questions

Is the Talaria MX5 the same bike as the Sting Pro?

Yes. Talaria Sting Pro, Sting MX5 Pro, MX5 Talaria and TL5500 all describe the same 72V model. The Pro suffix separates it from the earlier 60V Sting MX3 and Sting R MX4. If a listing says Sting Pro it is referring to the MX5 platform, and the model code on the documents will read TL5500.

What is the Talaria MX5 top speed?

The bike is delivered with a factory limit of 32 km/h, which is 20 mph. Once unrestricted for off road use, the top speed depends on the mode selected, rider weight, tyre choice and terrain. Talaria’s own figure for the unrestricted MX5 platform sits around 80 km/h, roughly 50 mph, in Hyper mode on flat ground.

How far will it go on a charge?

Talaria quotes 100 km at a constant 25 km/h. In real trail riding with Sport or Hyper mode the usable distance is considerably shorter and depends on terrain and how you ride. The pack is removable, so many owners carry a charged spare for long days out.

Can I ride the Talaria MX5 Pro on the road?

Only the road legal Talaria MX5, once it is registered, plated and insured and you hold the correct licence for its class. The off road version is for private land, practice tracks and organised events. Public roads, byways, bridleways and footpaths are off limits to it.

Does the Talaria MX5 use a belt or a chain?

The primary drive is a sealed, oil lubricated gearbox, and final drive is a 428 chain to a 48 tooth rear sprocket. There is no belt to stretch or snap. The gearbox oil is a scheduled service item and the chain needs normal cleaning, lubrication and tension checks.

Is the MX5 too much bike for a first electric dirt bike?

Not if you use the modes sensibly. Eco and Sport give a progressive throttle that suits a newer rider, and Hyper can be left alone until you are comfortable. Riders who already know they want the most capable Sting often buy the MX5 first rather than upgrading later.
