Brake Discs and Rotors

MOTOKS manufactures stainless steel brake discs in fixed and floating designs for scooters and motorcycles. Disc flatness, runout and heat treatment are controlled in-house, which is what separates a disc that stays true after 10,000 km from one that develops pulsing within a few thousand.

What Matters in a Brake Disc

Runout tolerance: the direct cause of brake pulsing under lever pressure.
Disc thickness and minimum wear thickness: must match the caliper and pad set.
Floating vs fixed: floating discs handle heat expansion better under repeated hard use.
Mounting hole pattern and centre bore: confirm against OEM part number.

Rotor Range by Diameter

Five dimensions decide whether a rotor fits: outer diameter, thickness, mounting hole pattern, centre bore and offset. Confirm them against the OEM number before ordering — a 5 mm difference in diameter is enough to foul the caliper.

Rotor diameter	Typical fitment	Design	Thickness	MOQ
155 mm	125cc commuter scooter	Fixed, ventilated	Standard wear spec	100 pcs
160 mm	125cc scooter, front	Fixed, ventilated, full silver or black centre	Standard wear spec	100 pcs
170 mm	125–150cc scooter	Fixed, ventilated	Standard wear spec	100 pcs
180 mm	150–200cc dirt bike	Fixed, ventilated, black or hollow centre	Standard wear spec	100 pcs
220 mm	200–250cc motorcycle	Fixed, ventilated, large size	Standard wear spec	100 pcs
220 mm floating	GY6-125 / GY6-150, ZY125T	Floating, gold inner hub	Standard wear spec	100 pcs

Procurement Terms

Minimum order: 100 pcs per size. Several diameters can be combined in one shipment to build a mixed order.
Samples: Sample rotors are available so runout and fit are checked on the bike before a production run.
Lead time: 15–30 days after deposit. Express options are available for urgent restocking.
Customisation: Your logo on the hub or laser-etched on the carrier, private-label boxes, and dimension changes against a drawing where tooling allows.
Quality control: Flatness, runout and thickness are gauged on every disc, and heat treatment is controlled in-house. Surface finish and hole pattern are inspected before packing.
Payment and shipping: T/T with 30% deposit. FOB, CIF or EXW terms, shipped from Guangzhou to ports worldwide.

Brake Disc Sourcing FAQ

Should I choose fixed or floating discs for my range?

Fixed discs are the cost-effective default for scooters and commuter bikes. Floating discs are the better choice for performance, off-road and heavy-load applications where repeated hard braking causes significant heat expansion.

How is runout controlled?

Flatness and runout are gauged on every disc after heat treatment, and heat treatment itself is controlled in-house rather than subcontracted. That is what keeps a disc true at 10,000 km instead of pulsing after a few thousand.

Can you match a specific OEM disc dimension?

Yes. Send the OEM part number or a dimensioned drawing covering outer diameter, thickness, mounting hole pattern, centre bore and offset, and we will confirm tooling availability.
