Commuter heads are a volume business with thin margins and no patience for delays. The buyer is usually an importer supplying thousands of workshops, or a regional brand feeding an assembly line, and both measure a supplier on three things: mold coverage, batch consistency and delivery rhythm. Unit engineering matters, but it matters inside a logistics promise.
Our commuter range covers the highest-population platforms in the segment — applications for Honda CG125, CG150 and the Wave and XRM underbone families, Bajaj Boxer, CT100 and Pulsar, TVS Apache and Star City, Hero Splendor, Yamaha YBR125 and Crypton, Suzuki AX100 and GS125 — plus full coverage of the CG-clone horizontal engines from Lifan, Zongshen and Loncin that dominate African and Middle Eastern fleets, and GY6 scooter engines from fifty to one-fifty. Heads ship as bare castings or complete assemblies, with CKD supply available for local assembly programs.
Most of these platforms are already in our mold library, which is what keeps lead times short: no tooling wait, no prototype loop, just a production slot. Where a platform is missing, we open tooling from a sample on the same low-volume economics we run across the catalog.
CG125/CG150 Heads
The CG family is the highest-volume commuter engine ever built; our heads cover both the one-twenty-five and one-fifty generations, cataloged by casting variant.
Wave 110/125 Heads
Underbone heads for the Wave family, a platform where fuel quality across Southeast Asia makes hardened seats essential; ours are fitted as standard.
XRM 125 Head
Coverage for the XRM one-twenty-five, the dominant underbone in the Philippine market, with correct rocker and decompressor layout.
TMX 155 Head
The TMX one-five-five serves tricycle fleets that run all day at full load; heads for this platform get reinforced fin area at the exhaust side.
Boxer BM150 Head
Fleet-grade replacement for the Boxer, the default workhorse across African and South Asian boda fleets, built for fuel of unpredictable quality.
CT100 Head
The CT100 head serves the entry commuter segment where price tolerance is thinnest and volumes are largest; short-cycle die casting keeps the economics workable.
Pulsar 135/150 Heads
Covers the Pulsar family in the one-three-five and one-fifty generations, including the twin-spark head variants cataloged as separate part numbers.
Discover 125 Head
Discover family heads produced to the original two-valve OHC layout, a steady mover in South Asian aftermarket channels.
Apache RTR 160/180 Heads
Replacement heads for the Apache RTR family, the sportiest platforms in this category, with chamber volumes held tight for their higher compression.
Star City 110 Head
The Star City one-ten head covers TVS's core commuter platform, produced on automated machining cells for batch consistency at volume.
Splendor 100 Head
Splendor heads serve the single largest motorcycle nameplate in the world; we run this part number continuously, not in campaigns.
Hero CD100 Head
Coverage for the CD100 and related Hero commuter singles, an enormous installed base across South Asia and East Africa.
YBR125 Head
The YBR125 head covers Yamaha's global commuter single, a platform sold on every continent with year variants we catalog separately.
Crypton/T115 Heads
Underbone heads for the Crypton family, including the T-one-fifteen generation, machined to the original OHC specification.
Suzuki AX100 Head
The AX100 is the two-stroke that refuses to retire across Africa and South Asia; our heads keep the original squish geometry for low-grade fuel tolerance.
Suzuki GS125 Head
GS125 heads for Suzuki's long-running commuter single, with hardened seats fitted as standard for unleaded and low-grade fuels.
CG-Clone 125/150/200 Heads
Horizontal CG-clone engines from Lifan, Zongshen and Loncin power most of Africa's motorcycle fleet; we cover the three displacement generations with variant-level cataloging, because clone families differ in oil feed and mount details.
GY6 50/125/150 Heads
GY6 scooter heads in three displacements, the backbone of the global scooter aftermarket, produced on short-cycle die casting lines.
Horizontal C100/C110 Heads
Cub-family horizontal heads for the C100 and C110 architecture shared by dozens of brands, one of the deepest mold positions in our library.
70cc Moped Heads
Seventy-cc class heads for mopeds and entry underbones, a price-sensitive segment where our tooling is already amortized and lead times are shortest.

Commuter platforms run on our high-volume lines: short-cycle die casting cells for the high-population parts, T6 heat treatment, and automated machining cells that hold seat, guide and deck dimensions without operator drift across long runs. The process chain is the same one described on our cylinder head machining page, tuned here for throughput rather than small-batch flexibility.
Volume does not relax inspection. Every batch is sampled on CMM, leak-tested and checked for deck flatness, with results filed against the part number. For assembly-plant customers we supply CKD kits with heads, valve train and gaskets grouped to line requirements, and batch records follow each kit so incoming inspection at the plant stays simple.
The library covers the highest-population platforms in the segment: the Honda CG family and underbones, Bajaj Boxer and Pulsar, TVS and Hero singles, Yamaha and Suzuki commuters, CG-clone horizontal engines in three displacements, and GY6 scooter heads. Platforms already in the library move straight to production scheduling with no tooling wait. Send your model list and we confirm coverage within one working day.
Yes. CKD supply groups heads, valve train components and gaskets to your line's requirements, with batch records following each kit. We support assembly-plant programs from pilot lines through full production, and kit contents are fixed in writing before the first shipment.
High-population part numbers run on automated machining cells, which removes operator drift across long runs. Every batch is sampled on CMM, leak-tested and checked for deck flatness, with results filed against the part number — so the thousandth container matches the first approved sample.
Yes, and this is where cataloging discipline matters most. CG-clone engines from Lifan, Zongshen and Loncin share a family architecture but differ in oil feed layouts and mount details across manufacturers and years. We catalog each variant as its own part number and confirm which clone family your market runs before quoting.
Yes. Neutral boxes, private-label cartons and full regional-brand packaging are all standard options, and carton artwork follows your brand guidelines. Many of our commuter-market accounts run their own brand on our castings, and we support that arrangement as a matter of routine.
The engine code stamped on the crankcase is the fastest route, since commuter platforms are sold under different badges in different markets on the same engine. A casting number or photos of the original head close any remaining gap, and for clone engines a sample settles the question definitively.
The commuter segment forgives nothing. Margins are thin, buyers are exacting, and a supplier who misses a delivery window loses the account to one of a dozen alternatives. The notes below reflect how experienced importers and assembly plants buy in this category, and they apply to any source you evaluate.
Commuter motorcycles are the transport backbone of South Asia, Southeast Asia, Africa and Latin America, and their engines live brutal lives: overloaded bikes, low-grade fuel, dusty roads, stretched service intervals and full-load running in slow traffic. Head failures are routine, and the replacement market is enormous, but it buys on price, availability and consistency rather than engineering novelty. The winning supplier in this segment is the one with the deepest mold library and the most predictable delivery rhythm, because the buyer's entire business is keeping workshops supplied without interruption.
| MODEL | HOW IT WORKS | BEST FOR |
|---|---|---|
| Aftermarket wholesale | Container-load finished heads, neutral or private-label packaging | Importers supplying workshop networks |
| OEM program | Heads built to the brand's drawings and specification, batch records per shipment | Regional motorcycle brands and assemblers |
| CKD supply | Kits grouped to assembly-line requirements, with valve train and gaskets | Local assembly plants building under license |
Many accounts in this category run two models at once: CKD kits for their assembly line and packaged finished heads for the aftermarket side of the business. We support both from the same production records, which keeps the two channels consistent.
The CG-clone horizontal engine is the highest-population powerplant in the developing world, built by Lifan, Zongshen, Loncin and dozens of smaller factories, and installed under hundreds of brand names. The architecture is shared, but oil feed layouts, mount details and cylinder head variants differ between manufacturers and across years. Heads that look interchangeable are often not, and the error shows up as oil starvation in the valve train within the first thousand kilometers. The defense is cataloging: every variant needs its own part number, and every inquiry needs the engine code or a sample, never just a brand badge. We catalog clone variants individually for exactly this reason.
Price pressure in this segment pushes some suppliers to skip steps, and the failures arrive months later in your warranty claims. Three items should survive any price negotiation. Hardened valve seats: low-grade fuel destroys soft seats, and inserts cost little at the foundry. Leak testing per batch: a porous head in a fleet market multiplies into a reputation problem. And deck flatness verification: warped decks are the leading warranty item on air-cooled commuters that idle in traffic. A supplier who quotes without these is quoting a different product.
Ask which platforms are already tooled, because a supplier quoting tooling for a CG125 head is telling you they do not serve this market. Ask about continuous production versus campaign production, since a part number run continuously holds its process steady while campaign production drifts between batches. Ask how mixed loading works, because your container economics depend on combining fast and slow movers in one shipment. And ask for batch records on a sample order before committing to a program — the paperwork you receive on a trial shipment is the paperwork you will receive at volume. For adjacent categories, our dirt bike cylinder heads and V-twin cylinder heads pages cover the performance and custom segments.
