Honda CB1100 Parts & Accessories

The Honda CB1100 is a modern retro motorcycle powered by an air-cooled 1140cc DOHC inline-four engine, reviving the classic styling and mechanical character of Honda's most iconic air-cooled four-cylinder motorcycles from the 1970s and 1980s. Honda built the CB1100 to offer the visual appeal of vintage machines alongside the reliability of contemporary engineering, including fuel injection, liquid-cooled oil cooling, and modern suspension geometry. The platform has grown into a well-supported aftermarket with exhaust, suspension, and cosmetic upgrades available from multiple manufacturers. Owners keeping a CB1100 in top condition will find quality parts across every service category listed here.

Popular Upgrades

Vance and Hines and Delkevic produce slip-on and full exhaust systems for the CB1100 that improve exhaust note and reduce system weight on the 1140cc air-cooled engine. Cobra and Dynojet Power Vision fuel tuners correct fueling when a full exhaust removes the original catalytic converter. Progressive Suspension rear shocks and Eibach fork springs improve handling response and load capacity. K&N air filters and Metzeler or Pirelli tires in OEM dimensions round out the most common service and upgrade parts.

Performance and Handling

The CB1100 chassis is tuned for smooth, stable riding at highway speeds, and suspension improvements focus on increasing damping quality and spring preload range beyond the standard OEM specification. Fork spring upgrades reduce front dive under braking and improve feedback in corners. Rear shock replacement from Progressive Suspension or Ohlins delivers the most significant handling improvement for riders who regularly carry a passenger or tour with luggage attached to the frame.

What exhaust fits a Honda CB1100?

The CB1100 uses a four-into-two or four-into-four exhaust configuration depending on the production year and market, and Vance and Hines produces slip-on canisters that match the original pipe diameter and mounting positions. Full exhaust systems from Delkevic and Cobra significantly reduce exhaust weight while improving sound character. A Dynojet Power Commander V corrects fueling when a full exhaust system removes the original catalytic converter.

How do you adjust valve clearance on a Honda CB1100?

Valve clearance on the CB1100 is adjusted using the shim-over-bucket method requiring camshaft removal to access and measure individual shims at TDC compression for each cylinder. Intake clearance specification is 0.15 to 0.25mm and exhaust is 0.21 to 0.30mm when cold, measured with a feeler gauge between the cam lobe and shim surface. Honda recommends valve clearance inspection at 8,000-mile intervals on the CB1100.

Why These Parts Fit Right
