Honda CB450SC Nighthawk Parts & Accessories

The Honda CB450SC Nighthawk is a Honda motorcycle powered by a twin-cylinder engine displacing 450cc, representing a platform that has earned strong enthusiast support across decades of vintage motorcycle culture and aftermarket development. The SC designation indicates the standard Nighthawk variant, which featured a more relaxed riding position and shaft drive compared to sportier alternatives of the era. Riders seeking to maintain peak performance or restore this classic will find that the CB450SC Nighthawk responds well to bolt-on improvements available from established manufacturers.

Exhaust and Intake

Aftermarket exhaust systems are among the most popular upgrades for the CB450SC Nighthawk, with slip-on and full-system options available that restore or improve midrange torque delivery. A performance exhaust paired with a rejet unlocks the full benefit of increased flow. Pod filters and high-flow intake kits improve throttle response when the carburetor is tuned to match the increased airflow.

Suspension Upgrades

The CB450SC Nighthawk factory suspension benefits from modernized upgrades when pushing the bike harder or carrying a passenger. Hagon and YSS offer direct replacement rear shock units that raise the performance ceiling without requiring custom fabrication. Upgrading the suspension also improves braking stability under hard deceleration by controlling fork dive more precisely than the original OEM valving.

Brakes and Drivetrain

EBC and Ferodo brake pads are popular replacements for the OEM friction material on the CB450SC Nighthawk, offering improved initial bite and better fade resistance under repeated stops. Galfer braided stainless steel brake lines replace the stock rubber hoses to firm up lever feel by eliminating hose expansion under pressure. Drive chain and sprocket sets from DID and Renthal are standard wear items that are often upgraded to heavier-duty specifications for extended service life.

What Engine Does the Honda CB450SC Nighthawk Use?

The Honda CB450SC Nighthawk uses a twin-cylinder engine displacing 450cc with DOHC valve actuation that delivers smooth power across the rpm range. The engine architecture is reliable and responds well to carburetor tuning and exhaust upgrades for modest power improvements while retaining the tractable character that makes the platform enjoyable in everyday riding.

Ignition and Electrical

A performance ignition system eliminates the wear-prone points ignition on older CB450SC Nighthawk models and provides a more consistent spark advance curve across the rpm range. LED lighting conversions reduce electrical load on the stock charging system and improve visibility. A high-flow intake system rounds out the performance package when the ignition and exhaust upgrades are already in place.

Maintenance Parts

Keeping the CB450SC Nighthawk in top operating condition requires attention to consumable parts including air filters, oil filters, spark plugs, fuel lines, and gasket sets. NGK spark plugs are direct replacements that provide reliable ignition across all operating temperatures. Carburetor rebuild kits and petcock repair kits are common service items on older CB450SC Nighthawk models that restore proper fuel delivery after years of storage or use.
