Honda 600 Parts & Accessories

The Honda 600 series, comprising the N600 sedan and Z600 coupe, represents Honda's first entry into the North American automotive market in the early 1970s, bringing the company's motorcycle engineering philosophy to an ultra-compact four-wheel platform. The 598cc air-cooled two-cylinder engine produced respectable power relative to the N600's approximately 1100-pound curb weight, and the car's light construction gave it handling agility that surprised many contemporary drivers. Today, Honda 600 examples are collected for their historical significance as the starting point of Honda's American automotive story, and a dedicated restoration community maintains technical knowledge and parts sourcing resources for these rare machines. The Z600 coupe has particular collector appeal due to its fastback styling and limited production numbers compared to the more common N600 sedan.

Popular Upgrades

Carburetor rebuild kits and jet upgrades for the Honda 600's Keihin carburetors are among the most requested parts for running restoration projects, with motorcycle-sourced kits often compatible due to the shared Keihin design lineage. Exhaust upgrades and replacement systems are needed for most running Honda 600 examples because original pipes have typically rusted after decades of use. Ignition system restoration kits and electronic ignition conversions improve reliability over the original points-based system. Suspension bushings and ball joint replacements address the common age-related wear that affects steering precision and handling on these vintage machines.

Performance and Handling

The Honda 600's front-wheel-drive layout with a transversely mounted engine was uncommon in the North American market of its era and delivers neutral handling when the suspension is properly maintained. Tire sourcing for the Honda 600 requires attention to the small wheel dimensions used on this platform, with vintage-compatible radial options available from Toyo and Nankang in the required sizes. Brake system restoration is critical given the age of surviving Honda 600 examples, with front disc and rear drum configurations requiring complete hydraulic system evaluation on any example that has sat idle for extended periods. Weight savings from the Honda 600's original design means that engine performance upgrades have a proportionally greater effect on performance than they would on heavier contemporary vehicles.

What engine is in the Honda 600?

The Honda 600 (N600 and Z600) used a 598cc air-cooled two-cylinder engine mounted transversely in the front of the vehicle, derived from Honda's motorcycle engine design philosophy. Output was approximately 36 horsepower, which was adequate for the extremely light 1100-pound N600 body. The engine's motorcycle DNA means Honda motorcycle carburetor expertise translates well to servicing the Honda 600's Keihin units.

Are Honda 600 parts still available?

Honda 600 parts availability relies primarily on NOS inventories, specialty microcar suppliers, and the active vintage Honda 600 community that maintains parts interchange documentation. Engine components including pistons, rings, gaskets, and bearings are findable through Honda motorcycle parts suppliers because of the shared engineering heritage. Body panels and trim pieces are more difficult to source and often require custom fabrication or sourcing from parts vehicles.

Why These Parts Fit Right

Parts in this Honda 600 collection are confirmed for the N600 and Z600 platform's specific engine dimensions and chassis mounting points. The Honda 600's shared engineering roots with Honda's motorcycle line means some engine components cross-reference to Honda motorcycle part numbers, expanding the available supplier ecosystem. Body-specific parts remain the most challenging to source and require confirmation against the N600 or Z600 body style designation for correct fitment.

Riders looking to build out their Honda 600 can also explore exhaust systems, suspension upgrades, and air intake systems for a fully optimized build.
