190mm Brake Disc for Custom Pit Bike Disc-Brake Wheels
New aftermarket 190 mm brake rotor intended for a custom pit-bike wheel that already has a compatible disc-brake hub and brake assembly.
Fitment
Suitable only for a correctly dimensioned aftermarket disc-brake wheel. A CRF50/XR50-style project may use this type of rotor after a suitable wheel and brake conversion; it does not fit an original drum-brake wheel.
SDG-style wheel mounting reference
- Nominal disc outside diameter: 190 mm
- Typical SDG-style centre opening: 76 mm
- Typical SDG-style mounting: 4 bolts, 100 mm between opposing hole centres
- Position: Front or rear only where the existing wheel and brake setup match
- Condition: New, unbranded aftermarket replacement
The mounting dimensions above describe the common SDG-style 190 mm disc family, not individual measurements of this stock item. Check the existing disc's thickness, mounting-hole size, bolt-head seating, centre bore and offset before purchase.
What's Included
1 × 190 mm brake disc. No fixing bolts or additional conversion components are specified as included.
Important Compatibility Check
Not a direct factory Honda CRF50/XR50 replacement: standard CRF50/XR50 wheels use drum brakes. Engine size, bike branding or a CRF50-style frame does not establish brake-disc compatibility. Compare your actual hub, caliper, disc thickness, offset and four-hole mounting arrangement before ordering.
Condition
New, unused aftermarket brake disc.
