Honda CB400F CB-1 Parts & Accessories

The Honda CB400F CB-1 is a Honda motorcycle powered by a four-cylinder engine displacing 400cc, representing a platform that has earned strong enthusiast support across decades of sport motorcycle culture and aftermarket development. The CB-1 brought the inline-four configuration to the 400cc class in a compact, sporty package featuring fully-enclosed bodywork and a race-derived seating position. Riders seeking to maintain peak performance or restore this distinctive machine will find that the CB400F CB-1 responds well to bolt-on improvements available from established manufacturers.

Exhaust and Intake

Aftermarket exhaust systems are among the most popular upgrades for the CB400F CB-1, with slip-on and full-system options available that reduce weight and 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 set is tuned to match the increased airflow across all four cylinders.

Suspension Upgrades

The CB400F CB-1 factory suspension benefits from upgrades when pushing the bike harder in corners or improving ride quality for daily use. Progressive Suspension and Hagon offer direct replacement fork springs and 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 OEM valving.

Brakes and Drivetrain

EBC and Ferodo brake pads are popular replacements for the OEM friction material on the CB400F CB-1, 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 CB400F CB-1 Use?

The Honda CB400F CB-1 uses a four-cylinder engine displacing 400cc with DOHC valve actuation and individual carburetors per cylinder. The engine architecture is responsive to jet kit upgrades and exhaust modifications, and benefits from carburetor synchronization to ensure balanced power delivery across all four cylinders at part throttle.

Ignition and Electrical

A performance ignition system eliminates the wear-prone components on older CB400F CB-1 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 CB400F CB-1 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 for all four carburetors and petcock repair kits are common service items that restore proper fuel delivery after years of storage or use.
