Fitment FAQ

Will this part fit my specific model and year?

This brake assembly is intended for Vehicle Category; Displacement / Series; Common Compatible Models; Sport & Street Bikes; 600cc, 750cc, 900cc, 1000cc; Honda CBR600/1000, CB900; Suzuki GSXR 600/750/1000; Dirt & Pit Bikes. Key physical/spec details from the product data include 600cc, 750cc, 900cc. Use the compatibility table and product photos together before ordering.

Do I need to match the OEM part number?

Yes. If your original part has a stamped OEM or manufacturer number, match that number first before ordering. For this brake assembly, also compare the caliper bolt spacing, brake hose length, master-cylinder bore, lever side, banjo fitting angle, drum/hub dimensions, and handlebar diameter. This is especially important for Honda/Suzuki CB900/CBR600 models because similar model names can use different parts by year or trim.

What models or situations does this part not fit?

Do not order this brake assembly for machines outside the listed compatibility, or for units with different caliper spacing, hose routing, lever/master-cylinder setup, drum/hub dimensions, or handlebar diameter. Do not rely only on the model name or engine size.

What should I check before ordering?

Before ordering, compare your original part with the photos and check the caliper bolt spacing, brake hose length, master-cylinder bore, lever side, banjo fitting angle, drum/hub dimensions, and handlebar diameter. Recheck listed specs such as 600cc, 750cc, 900cc. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
