STT Motorcycle sprockets & chains, made in Malaysia.
Straight from the STT factory, with the chains, brake pads and spares to go with them.

Our own sprockets, plus the parts riders usually replace at the same time.
One factory, a series for every rider: from everyday value to the hardest riding.
From a plain chain for everyday riding to a sealed X-ring for the hardest use. Sealed chains keep their grease inside the links, so they last longer and need less care.
01 · Everyday commuting
A plain black chain for standard replacement on small commuter bikes. Clean and lube it often and it keeps running smoothly.
02 · Work bikes and loads
Thicker plates for strength where it counts: delivery bikes, carrying loads and riding two-up. A plain chain that rewards regular lube.
03 · Daily riding, longer life
Rubber O-rings seal the grease inside every link, so the chain stays lubricated, stretches less and lasts far longer than a plain chain.
04 · Hard riding and racing
X-shaped seals touch the plates at four points instead of two: the sealed-in grease of an O-ring with less drag, for hard acceleration and long rides.
Every sprocket starts as a steel blank in our own factory. Point at a feature to see what goes into it. Need a tooth count we don't stock? We can make it.
Every tooth is induction-hardened, so the teeth resist wear while the core stays tough enough to take hard gear changes.
Teeth are CNC-cut to the 415, 420, 428, 520, 525 and 530 chain standards, so the chain seats exactly, runs quietly and wears evenly across every link.
Black and gold finishes protect the steel from rust and give the back of your bike a clean, sharp look.
Made in our own factory under an ISO 9001 quality system, with every batch checked before it is packed.
Every tooth is induction-hardened to HRC 40–45: hard enough to resist wear from the chain, on a tough core that takes hard gear changes without cracking.

The splined centre is cut to match your gearbox shaft, so the sprocket sits tight with no play and no rattle.

The front sprocket does the hardest work: fewer teeth carry the full engine force. Hardened teeth and an exact spline keep it going.

Soalan lazim tentang sprocket motor, spoket dan rantai: sizes, sets, ratios and where to buy in Malaysia.
Order online in our shop with delivery across Malaysia, or buy from an STT dealer near you: see Find a dealer. STT sprockets and chains (rantai) are made by Motorcycle Dealers Holdings in Ampang, Selangor.
The sprocket pitch must match your chain. STT makes sprockets (spoket) in 415, 420, 428, 520, 525 and 530 pitch. The size is stamped on the side of your chain and sprocket, or use Find My Parts to look up your bike, such as the Y15ZR, LC135, RS150 or Wave.
Front sprocket, rear sprocket and chain wear together, so it is best to change all three at once. A sprocket set (set sprocket dan rantai) puts a matched front sprocket, rear sprocket and chain in one box, ready to fit.
Change them when the sprocket teeth look hooked or sharp, when the chain has stretched so far that it can no longer be adjusted, or when the drive is noisy or the chain jumps on the teeth.
More teeth on the rear sprocket, or fewer on the front, gives quicker acceleration and a lower top speed; the other way round gives a higher top speed. Try different tooth counts in our sprocket ratio calculator.
Yes. STT sprockets are cut and hardened in our own factory in Ampang, Selangor, for motorcycles ridden in Malaysia, and sold through dealers across the country.
Spare parts shops, motor shops and online shops can register as STT-MDH dealers to buy at dealer prices.
