Front Rim Assembly 19” x 1.40” Sting MX3 / MX4 / X3

A Talaria front rim in the original 19 x 1.40 size, supplied as a built assembly with silver spokes and ready for your tyre, disc and axle, is the quickest way to put a bent or cracked front wheel behind you. It fits the Sting MX3, the Sting R MX4 and the X3 and restores the factory geometry, speed reading and tyre choice in one part. This page covers fitment, when a wheel is beyond truing, tyres and tubes, installation and care.

Is this the right Talaria front rim for your bike?

Three checks settle it. First, the model: this Talaria front rim is built for the Sting MX3, the Sting R MX4 and the X3, all of which run a 19 inch front wheel from the factory. Second, the rim size stamped or etched on your existing wheel, which should read 19 x 1.40. Third, the spoke colour, because this assembly uses silver spokes, the finish fitted to the standard MX3 and MX4 rather than the black spokes of the Expert edition.

If your bike is a road legal Sting, this is one of the few wheel purchases that needs no second thought, because a like for like Talaria front rim keeps the bike exactly as it was registered. A conversion to a different diameter, covered near the end of this page, is a different matter.

What the assembly includes

The word assembly is doing real work in the product name. This is not a bare hoop that you then have to lace, tension and true. This Talaria front rim is a 19 x 1.40 hoop laced with silver spokes and nipples to the front hub pattern used across the Sting and X3, built and trued so it can go straight onto the bike.

The rim

The 19 inch diameter and the 1.40 inch internal width of this Talaria front rim are the factory dimensions for the Sting and X3. That width is matched to the 70/100 x 19 front tyre these bikes are supplied with, giving the tyre the profile Talaria intended and keeping the bead seated under hard cornering on a rim lock.

Spokes and nipples

Silver spokes are the standard finish on the MX3 and MX4, and they are what this Talaria front rim is laced with. They are laced in the same cross pattern as the original wheel, so the wheel takes braking loads and side loads the way the frame and fork designers expected. Nipples are accessible with a standard spoke key, which matters when you come to re tension the wheel after its first few rides.

What is not included

• Tyre, tube and rim lock: choose these to suit your riding, see the tyre section below
• Brake disc and disc bolts: these transfer from your old wheel
• Front axle and spacers: reuse your originals, check them for wear first
• Bearings and seals: confirm what is fitted on delivery and grease before first use

When a front rim needs replacing

Many riders order a Talaria front rim before they need one, and a few keep riding one that should have been retired months ago. The dividing line is simple: a rim that can be trued back to round with spoke adjustment is a truing job, a rim that has taken a set or lost material is a replacement.

Replace it when

• There is a visible flat spot or dent in the rim wall from a rock or a kerb, however small
• A crack has started at a spoke hole, which shows as a hairline with a dark stain of dirt drawn into it
• The rim runs out of true by more than a few millimetres and truing brings one section straight while another goes out
• The bead seat is gouged so the tyre will not hold pressure with a new tube
• Spoke holes have elongated, which lets the nipples rock and the wheel loosen itself

True it when

A Talaria front rim with a gentle sideways wobble, no dents and even spoke tension is almost always recoverable with half an hour and a spoke key. The same is true after a spoke has broken and been replaced, provided the rim itself was not bent in the process. If in doubt, take the tyre off and sight the bare rim against a fixed point while spinning it; damage that hides under a tyre is obvious on a bare hoop.

Tyres, tubes and rim locks for a 19 x 1.40 rim

The factory tyre size for this Talaria front rim is 70/100 x 19, the standard front size on small wheel motocross bikes, which means UK riders have a wide choice of intermediate, soft and hard terrain patterns from every major tyre brand. Because the rim width is the correct match for that size, the tyre profile is neither pinched nor splayed.

Choosing a pattern

Most of the UK is soft to intermediate for most of the year, so an intermediate front knobbly is the sensible default for a Sting used on woodland and farm tracks. Riders who spend their time on hard packed quarry floors or rocky moorland benefit from a hard terrain pattern with more closely spaced knobs. For sand and deep mud a soft terrain front with tall, widely spaced blocks clears itself far better.

Tubes and pressures

Fit a heavy duty tube. The Sting’s front wheel is light and the bike carries less weight over it than a petrol machine, which encourages riders to run low pressures for grip, and a thin tube pinch flats on the first square edge. A 19 inch heavy duty tube with a matching rim tape is the combination we recommend for a Talaria front rim. Set pressures to the tyre manufacturer’s guidance for the terrain and check them cold before every ride.

Rim locks

A single rim lock stops the tyre creeping round the Talaria front rim under braking at low pressures and tearing the valve out of the tube. Fit it opposite the valve and balance the wheel afterwards with a small weight if you feel a shimmy at speed on hard ground.

Spoke tension, truing and bearings

Every laced wheel settles in its first hours of riding as the spokes bed into the hub flanges and the nipples seat into the rim. A new Talaria front rim is no exception, and the single best thing you can do for its life is a tension check after the first ride and again after the first few hours.

Checking tension

Tap each spoke on the Talaria front rim with a spoke key and listen. A tight spoke rings, a loose one thuds. Bring loose spokes up in quarter turns, working around the wheel in the same direction rather than tightening one spoke fully, and keep checking the rim against a fixed point. Even tension around the wheel matters more than absolute tightness.

Truing at home

With the Talaria front rim in the fork and the bike on a stand, hold a pen against the fork leg close to the rim and spin the wheel. Where the rim moves towards the pen, tighten the spokes on the opposite side a quarter turn and loosen the near side spokes the same amount. Small changes, patience and frequent spinning get you within a millimetre or two without a truing stand.

Bearings

The bearings behind a Talaria front rim live an easier life than the rear ones, but they are still exposed to jet washing and to deep water crossings. Spin the wheel with the brake calliper removed and feel for roughness or play. Sealed bearings are replaced rather than repacked, and the job needs a drift and care not to load the balls while driving the new bearing into the hub.

Fitting the front wheel

Swapping a Talaria front rim is a thirty minute job with the bike on a stand and a torque wrench to hand. The sequence below is written for the standard forks and applies equally to a bike upgraded with a Manitou Dorado.

1. Lift the front wheel clear of the ground on a paddock stand or a suitable block under the frame.
2. Remove the brake calliper from the fork so the disc lifts out cleanly, and hang it clear without stressing the hose.
3. Loosen the axle pinch bolts if fitted, withdraw the axle and lower the old wheel out.
4. Transfer the brake disc to the new Talaria front rim assembly using fresh threadlock on the disc bolts, and torque them evenly in a star pattern to the figure in your Talaria owner’s manual.
5. Fit the tyre, tube and rim lock, seat the bead with a burst of pressure, then set your riding pressure.
6. Offer the wheel up, fit the spacers as they came off, slide the axle through and tighten it to the manual’s torque figure before any pinch bolts.
7. Refit the calliper, centre it on the disc, pump the lever until firm and spin the wheel to check for rub.
8. Bounce the front end a few times so the fork legs settle on the axle, then tighten the pinch bolts.

Ride gently for the first few miles, then re check the axle, the disc bolts and the spoke tension. A wheel that was true on the bench can need a quarter turn here and there once it has been loaded.

Alternatives to the standard size

A like for like Talaria front rim is the right answer for most owners, but a front wheel purchase is also the natural moment to consider whether the standard size still suits your riding.

Stay with 19 inches if

You ride tight woodland where quick steering matters, you are shorter and value the seat height, your bike is road legal and registered on its factory wheels, or you simply want the bike back to how it was. A 19 inch rim Talaria Sting owners already know is the least disruptive choice, and it keeps the speedometer accurate.

Consider a change if

You want more rollover on rocky or rutted ground, in which case the KKE 21/18 wheel set for the MX3 converts the bike to full size motocross proportions. Or you ride mostly on hard surfaces and want a supermoto stance, which is what the 17 inch supermoto wheel set is for. Both change gearing, seat height and speed readings, and neither suits a registered road legal bike without informing your insurer, as GOV.UK guidance on vehicle insurance makes clear.

Matching the rear

If the rear wheel is also tired, the 16 x 1.85 rear rim completes the pair with this Talaria front rim in the factory sizes. Remember that the rear on this listing’s partner is finished in black, so match spoke colours front and rear if appearance matters to you.

Frequently asked questions

Does this Talaria front rim come with a tyre fitted?

No. The Talaria front rim assembly is the rim laced to the hub with silver spokes, built and trued. Tyre, tube, rim lock and rim tape are chosen and fitted by you or your workshop, which lets you pick the tread pattern that suits your riding rather than accepting whatever tyre a distributor had to hand. The factory size is 70/100 x 19.

Will it fit the Talaria Sting R MX4 with the larger front disc?

Yes. The MX4 uses the same 19 x 1.40 Talaria front rim as the MX3, and your existing disc bolts to the hub. Use fresh threadlock and a torque wrench on the disc bolts, and re centre the calliper after fitting. Only the spoke colour differs from the Expert edition, which runs black spokes.

Is a 19 inch rim Talaria Sting front the same as a 19 inch motocross front?

The rim and tyre dimensions match small wheel motocross bikes, so tyres, tubes and rim locks in 19 inch sizes are interchangeable. The hub, bearings and axle are specific to the Talaria, so a motocross front wheel will not bolt onto a Sting. This assembly is built on the Talaria hub pattern for that reason.

How often should I check the spokes?

After the first ride, after the first few hours, then at every wash. New wheels settle, and a quick tap round the spokes with a key takes less than a minute. A loose spoke left for a month becomes a broken spoke and, eventually, a rim that goes out of true beyond recovery.

Can I fit a bigger front tyre on this rim?

The 1.40 width is matched to a 70/100 x 19 tyre. Fitting a wider tyre on a Talaria front rim this narrow pinches the profile, makes the tyre roll on the rim in corners and can foul the fork or mudguard. If you want a larger front tyre footprint, the correct route is a wider rim or a 21 inch conversion, not stretching a tyre onto the standard rim.

Is the wheel covered by warranty?

Yes, the Talaria front rim assembly is covered by our UK warranty, full terms on the warranty page. Impact damage from rocks, kerbs or crashes and damage caused by riding with loose spokes or at very low pressure are wear and misuse rather than defects, which is why the spoke checks on this page are worth doing.
