Bullet alloy wheels do not come from the factory: every Bullet 350, Military, Standard or Black Gold, leaves the showroom on a spoked 19 inch front rim and a spoked 18 inch rear rim, with tube type tyres. Any Bullet with alloy wheels you see on the road has had them fitted later.
Changing wheels on this bike is more than swapping rims. The new wheel has to carry the right hub, brake disc or drum mounting and sprocket carrier, and you need tyres that match the rim, tube or tubeless. Below are the popular styles and the checks a good mechanic makes first.

What the factory fits on each Bullet 350
| Variant | Front wheel | Rear wheel | Tyres |
|---|---|---|---|
| Military | 19 inch wire spoke | 18 inch wire spoke, drum brake hub | 100/90-19 and 120/80-18 tube type |
| Standard | 19 inch wire spoke | 18 inch wire spoke, disc brake hub | 100/90-19 and 120/80-18 tube type |
| Black Gold | 19 inch wire spoke | 18 inch wire spoke, disc brake hub | 100/90-19 and 120/80-18 tube type |
So the honest answer to anyone asking about new standard bullet alloy wheels is that the Standard has none either. The sister Classic 350 alloy wheels page covers a bike that does get factory alloys on some trims, and the Hunter 350 alloy wheels page covers the roadster. The Bullet's identity is the spoked wheel, and Royal Enfield keeps it that way.
Royal Enfield Bullet 350 alloy wheels: the popular aftermarket styles
| Style | What it is | Watch for |
|---|---|---|
| S type | Cast wheel whose arms curve in an S shape from hub to rim | Thin arms on cheap castings; ask for the load rating |
| 3 spoke | Three wide straight arms, a sporty look | Heavier wheel, harder to balance by eye |
| Black finish | Powder coated or painted black alloy | Chips from stones show quickly; touch up early |
| Multi spoke | Many thin arms imitating a wire wheel | Hard to clean between the arms |
Owners searching for standard bullet alloy wheels usually mean one of these. The S type is the common pick at bullet accessories alloy wheels counters, while black alloys suit the darker paint schemes. Looks aside, judge any wheel by how it is cast and whether the seller can show the load it is rated for. A 195 kg bike with a pillion and luggage puts real load on the rear.
Hubs, brakes and the rear sprocket
Aftermarket alloys are usually sold as complete wheels with their own hubs. Before fitting, a mechanic must confirm:
- Axle size and spacers: the wheel must sit centred in the fork and swingarm.
- Front disc mounting: the 300 mm front disc and its bolt pattern must line up with the caliper.
- Rear brake type: a Military with a 153 mm rear drum needs a drum hub; Standard and Black Gold need a hub for the 270 mm rear disc.
- ABS sensor rings: on dual channel ABS bikes the toothed rings must sit at the exact gap or the ABS light comes on and the system shuts off.
- Sprocket carrier and cush drive: the chain line must stay straight.
Wheel bolt patterns on bikes are about discs and sprockets, not the car style PCD, though the measuring idea is alike; our PCD calculator shows how bolt circles are worked out.
Tube or tubeless after the change
The main reason riders want a Bullet 350 with alloy wheels is tubeless tyres: a nail bleeds air slowly instead of dropping the tyre flat. That only works if the alloy rim is made and marked for tubeless use and you fit tubeless tyres in the factory sizes, 100/90-19 and 120/80-18. Do not reuse the factory tube type tyres without tubes. Some cheap alloys need a tube anyway, which cancels the main benefit. Read tubeless tyre to see how the bead seals.
Ride, weight and paperwork
A wire wheel flexes a little over broken roads and is easy to true by adjusting spokes. A cast wheel is stiffer and cannot be trued; a crack means replacement. Heavy styles add unsprung weight, which you feel over speed breakers. Let the insurance company know, since non factory wheels can affect claims, and store the original spoked pair safely, since a dealer may want the bike back in stock form for warranty work.
Keeping black and painted alloys looking right
Hose off loose grit before touching the paint, then wash with diluted car shampoo and a soft bristled brush. Chain lube spray sticks to the rear wheel, so wipe it after each chain clean. Avoid acid cleaners, which dull black powder coat. Each month, spin the rear by hand with the bike on its centre stand, push the bike slowly to roll the front, and watch for runout or a fine crack at each arm's base. Our black alloy wheels guide covers paint touch ups.
Which is better for you: spokes or bullet alloy wheels
Keep the spokes if you love the classic look, ride rough village roads or want a wheel that a roadside mechanic can repair. Go for alloys if most riding is on tar, you hate tube punctures, and you are ready to pay for quality wheels plus proper fitting.

Questions owners ask
Is there a Bullet 350 variant with factory alloys?
No. Every trim, cheapest to costliest, rolls on 19 inch front and 18 inch rear wire spoked rims, tubed tyres included.
Can I fit S type alloys on my Bullet?
Yes, if the wheel set matches your bike's axle, brake mounting, ABS rings and sprocket carrier. Buy a set the seller confirms for your exact Bullet version and have a mechanic fit it.
Will alloys let me run tubeless tyres?
Only if the rims are made for tubeless use. Then fit tubeless tyres in the factory sizes, 100/90-19 front and 120/80-18 rear.
Are Classic 350 factory alloys a direct swap?
They share the same rim sizes, but hubs, brakes and ABS parts must match your Bullet. Ask a dealer to check part compatibility before buying.
Do alloys change the Bullet's ride?
A cast wheel feels a little firmer and cannot be trued like spokes. Heavy designs can make the bike feel slower to steer.
Is a 3 spoke alloy strong enough?
Strength depends on the casting quality and load rating, not the number of arms. Ask to see the load rating and a tubeless stamp on the rim.
