Complete Supermotor Wheel Set 17″ Sting MX4 / xXx

These are the supermotard wheels Talaria Sting R MX4 and xXx owners fit when they want the bike to live on tarmac, kart circuits and hard packed yards rather than mud. The kit is genuinely complete: two 17 inch wheels with black rims and silver spokes, road pattern tyres already matched to the rims, a 40T rear sprocket with a chain to suit, and 220 mm brake rotors front and rear. This page explains what is in the kit, why a supermoto conversion transforms a Sting, which models it fits, and how to set it up properly.

Everything in the 17 inch kit

Most supermoto conversions for small electric bikes are sold as bare wheels, leaving the owner to source tyres, a sprocket, a chain and discs from four different suppliers and hope the sizes agree. These supermotard wheels Talaria owners can order from us as one kit avoid that. Everything below arrives together, matched, so the bike can be converted in one session.

• Front wheel: 17 inch black rim laced with silver spokes to a hub built for the Sting front axle
• Rear wheel: 17 inch black rim with silver spokes on a hub carrying the sprocket and rear disc mounts
• Front tyre: 70/90 x 17 road pattern, as specified by the kit maker
• Rear tyre: 90/80 x 17 road pattern, as specified by the kit maker
• 40T rear sprocket with a chain cut to match
• 220 mm brake rotors, one front and one rear

The black rim and silver spoke combination is a deliberate look. Against a black Sting the bright spokes read as classic supermoto, and the finish is straightforward to keep clean because road riding throws far less grit at the wheels than a trail does. What these supermotard wheels Talaria MX4 riders order do not include is a set of 203 mm rotors for the Sting MX3, and that matters for fitment, as the table further down explains.

The supermotard wheels Talaria conversion logic

Fitting the supermotard wheels Talaria owners buy as a complete kit is not simply a tyre change. Swapping from the 19 inch front and 16 inch rear that the Sting ships with to a pair of 17 inch wheels wearing road tyres alters the geometry, the contact patch and the way the bike loads its suspension. Understanding those changes is what separates a conversion that feels planted from one that feels odd.

Rolling diameter and geometry

A 70/90 section tyre on a 17 inch rim has a rolling diameter of roughly 558 mm, against about 623 mm for the standard 70/100 x 19 front. The rear 90/80 x 17 comes out at roughly 576 mm, very close to the standard 90/100 x 16 at around 586 mm. The front therefore drops by around 65 mm while the rear barely moves, which tips the bike slightly forward, steepens the steering angle and shortens the trail. That is precisely why supermotard wheels Talaria owners fit make the bike turn in so quickly.

Contact patch and grip

Knobbly tyres put a small number of blocks on the ground at any moment and squirm as those blocks flex. A road tyre puts a continuous band of rubber down, so braking, cornering and acceleration all act on a far larger footprint. On a smooth surface the difference is dramatic: the Sting stops shorter, leans further and drives out of corners without the rear stepping sideways. The same tyres offer almost nothing on wet grass or loose gravel, which is why supermotard wheels Talaria owners fit as a second set beat a compromise tyre.

Suspension behaviour

Road tyres do not deflect the way knobblies do, so the fork and shock feel every ripple in the surface. Many riders add a few clicks of compression damping and a little more sag at the rear once the supermotard wheels Talaria riders choose are on, so the bike squats under power instead of skipping. There is no need for new springs on a standard Sting; the adjusters cover it.

Which Talaria the supermotard wheels fit

The supermotard wheels Talaria Sting R MX4 and xXx owners receive are built around the 220 mm discs both bikes run from the factory. The Sting MX3 shares the same axle and swingarm layout but uses 203 mm discs and matching caliper brackets, so it needs a different rotor size. The matrix below sets it out.

If you own an MX3 and already have 203 mm rotors on your standard wheels, they can be moved across to the hubs on these supermotard wheels Talaria MX3 riders order, using fresh bolts and threadlock. If your discs are worn or warped, order a new pair at the same time. Owners of the xXx will find the swap identical to the MX4 procedure, because both bikes share the same brake package and axle sizes; you can browse the full Talaria XXX and X3 range for the model specifics.

Tyres, pressures and warm up

The tyres on the supermotard wheels Talaria owners receive are chosen to suit the rim widths, so there is nothing to size. What the owner controls is pressure, and this is where new supermoto riders go wrong most often.

Pressures

Off road habits do not transfer. Knobblies run soft to conform to terrain; road tyres need enough pressure to hold their profile under cornering load, otherwise the sidewall folds and the bike feels vague on the edge of the tyre. Start at the pressure marked on the tyre sidewall, ride a few laps, then drop a small amount at a time until the feel is right. Rear pressure controls drive grip, front pressure controls steering precision. Get both right and the supermotard wheels Talaria newcomers fit feel planted from the first session.

Warm up and scrubbing in

The road tyres on these supermotard wheels Talaria kits carry a release agent from the mould and are slippery for the first few miles. Ride gently, lean progressively further each lap, and avoid hard braking until the shine has gone from the whole tread. On a cold day the tyres never reach the temperature they would on a heavier petrol supermoto, so treat the first minutes of every session as scrub in.

Tubes and rim locks

Rim locks are unnecessary at road pressures; the higher inflation grips the bead firmly, and a rim lock would only unbalance the wheel. If the wheels are supplied with tubes, carry a spare front tube, because a 17 inch front is a common motorcycle size but not one every garage stocks.

The 40T sprocket, chain and speed readout

The supermotard wheels Talaria owners order arrive with a 40T rear sprocket and a chain matched to it. Check the tooth count on the sprocket currently fitted to your bike: if it is larger than 40, the conversion lengthens your gearing and the bike gains top end at the cost of some initial punch; if it is the same, the gearing is unchanged apart from the small diameter difference at the rear tyre.

With the rear rolling diameter within about 10 mm of standard, the Sting’s speed readout stays close to true, unlike a big wheel conversion where the display reads well under. Fit the chain at the correct slack for the Sting, roughly the figure in the owner’s manual measured at the tightest point of the run, and check it after the first ride because new chains settle. Line the sprocket up with the front by sighting down the chain run from behind the bike; the Sting’s adjuster marks are a starting point, not a guarantee.

For riders chasing straight line speed on a private circuit, our Sting R top speed guide explains what gearing, tyre diameter and controller settings each contribute, and why the road tyres fitted to these supermotard wheels Talaria owners choose are the fastest way to actually use that speed.

220 mm rotors and braking on tarmac

Braking is where the supermotard wheels Talaria owners fit earn their keep. A road tyre on a smooth surface can transmit far more braking force than a knobbly on dirt, so the brakes become the limiting factor rather than grip. The 220 mm rotors supplied with the kit are the MX4 standard size, which keeps the calipers, pads and hydraulic system exactly as Talaria designed them while giving you fresh, flat discs to start from.

Bedding the new discs

The rotors supplied with these supermotard wheels Talaria sets need pad material transferred onto them before they bite properly. Do a series of firm stops from moderate speed without coming to a halt, let the discs cool for a minute, then repeat. After a dozen cycles the lever feel firms up and the initial bite sharpens. Skipping this step and grabbing a handful on the first lap glazes the pads and leaves a brake that feels wooden for weeks.

Front brake technique changes

On dirt, the rear brake does a lot of the work and the front is used carefully. On supermotard wheels Talaria riders should reverse that habit. The front provides most of the stopping power on tarmac, and the rear is used to settle the chassis and, for those who learn it, to slide the rear into a corner. Expect the fork to dive more under hard braking, and adjust compression damping if it bottoms.

Fitting sequence and torque care

Because these supermotard wheels Talaria riders buy arrive as a complete kit, fitting is a single afternoon on a stand. Work in this order and the bike is right first time.

1. Support the bike so both wheels are clear of the floor, then remove the front and rear axles. Bag the original spacers, adjuster blocks and washers together and label which end they came from.
2. Fit the 220 mm rotors to the new hubs with fresh threadlock on each bolt, tightening in a star pattern to the figure in the Talaria manual.
3. Fit the 40T sprocket to the rear hub the same way, checking it sits flat and runs true when spun.
4. Install both wheels using the spacers supplied with the set, fit the new chain, and set the slack before tightening the rear axle.
5. Torque both axle nuts with a torque wrench. Over tightening a Sting axle preloads the bearings and shortens their life; under tightening lets the wheel walk in the swingarm.
6. Spin each wheel, confirm the disc runs centrally in the caliper, then pump the brake lever and pedal until the pads seat against the new rotors.

After the first ride

Recheck the chain slack, go round every spoke with a spoke wrench and bring any loose ones up to match their neighbours, and confirm the axle nuts are still at torque. New spokes bed into the nipples on the first hard laps and a quick check now prevents a loose wheel later. Bearings need no attention beyond the usual play check at each wheel removal; the higher speeds supermotard wheels Talaria owners reach on tarmac make a rumbling bearing easier to feel through the bars, so do not ignore it.

Swapping back to dirt wheels

Many owners keep their standard 19 and 16 inch wheels with knobblies fitted, so the bike can switch between disciplines in twenty minutes. That reversibility is the main reason supermotard wheels Talaria owners buy as a complete set rather than as a tyre swap. Store the unused set with tyres inflated, out of sunlight, and the discs wrapped so they do not pick up corrosion. If the original front wheel has taken a beating, a replacement 19 x 1.40 front rim assembly restores it, and riders who want the opposite conversion can look at the KKE 21/18 big wheel set instead.

Road legal owners: read this first

An off road Sting R MX4 or xXx on supermotard wheels Talaria riders use for tarmac remains an off road bike. Road tyres do not make it road legal, and it may still only be ridden on private land with the landowner’s permission, never on public roads, byways, bridleways or footpaths. That said, the supermoto layout is exactly what many riders want on a registered Sting L1e or L3e, and there the picture is different.

A registered Sting is approved as a complete package, and wheel diameter, tyre size and brake components all sit within that approval. Fitting the supermotard wheels Talaria L1e and L3e owners want is a modification you must declare to your insurer before riding; the government guidance on vehicle insurance is clear that undeclared modifications can void a policy. On an L3e the tester will expect the tyres to be road rated, correctly sized for the rims, in good condition and with legal tread depth. The road pattern tyres supplied with the kit are a far better starting point for that inspection than knobblies ever were, but confirm the load and speed ratings on the sidewall before booking the test.

Whatever the registration status, wear proper kit. Supermoto riding on tarmac produces higher speeds and longer slides than trail riding, and a road approved helmet that meets the standards on the motorcycle safety helmets page, along with gloves, boots and abrasion resistant clothing, is the minimum. Riders who want a bike that is road legal from the outset can compare the options in our road legal Talaria category.

Frequently asked questions

Will these supermotard wheels fit my Talaria Sting MX3?

Yes, mechanically the supermotard wheels Talaria MX3 owners order fit the standard axles and swingarm, but the MX3 uses 203 mm brake discs rather than the 220 mm rotors included in the kit. You will need to fit a pair of 203 mm discs, which are not included. Your existing MX3 discs can be transferred if they are in good condition.

Are the tyres included, or do I need to buy them?

The tyres are included with the supermotard wheels Talaria kit and already matched to the rims: a 70/90 x 17 front and a 90/80 x 17 rear in a road pattern. The kit also includes the 40T sprocket, a matching chain and two 220 mm rotors, so nothing else is needed for an MX4 or xXx conversion.

Does the 17 inch wheel set make the Sting faster?

Not by itself. The rear rolling diameter is within about 10 mm of standard, so gearing is almost unchanged unless the 40T sprocket differs from the one on your bike. What supermotard wheels Talaria owners notice is how much more of the bike’s performance they can use: road tyres on tarmac allow harder braking, deeper lean and cleaner drive out of corners.

Do I need to change the suspension settings?

New springs are not needed for a supermotard wheels Talaria conversion. Most riders add a little compression damping front and rear and run slightly more rear sag, because road tyres transmit surface detail directly into the suspension and the bike brakes harder. Make one change at a time and ride between adjustments.

Can I ride a supermoto converted MX4 on the road?

No. An off road Sting R MX4 or xXx stays an off road vehicle regardless of its tyres and may only be ridden on private land with permission. Only the registered L1e and L3e Sting models can be used on public roads, and any wheel change on those must be declared to the insurer.

How long does the conversion take?

With a stand, a torque wrench and the kit unpacked, a first time fitting takes an afternoon. Once the rotors and sprocket are on the new hubs, swapping between the supermotard wheels Talaria tarmac riders prefer and the original dirt wheels takes around twenty minutes each way.
