190mm SDG-Style Pit Bike Brake Disc for 4-Bolt Wheels
New aftermarket 190 mm brake rotor for compatible SDG-style four-bolt pit-bike wheels. Check the physical mounting details rather than selecting by engine capacity.
Fitment
For 110–160 cc pit-bike applications only where the wheel already uses the matching 190 mm SDG-style mounting pattern, correct disc thickness and offset. Some front and rear wheels use different disc specifications.
SDG-style wheel mounting reference

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 universally interchangeable: front and rear SDG-style hubs can require different rotor profiles, bolt seats or offsets. 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.
