Honda ATC70 Parts & Accessories

The Honda ATC70 is one of the most iconic youth three-wheelers ever produced, introducing countless riders to off-road riding through its approachable 70cc four-stroke engine, automatic transmission, and forgiving power delivery that made it an ideal first ATC for younger riders and beginners of all ages. Produced across a long model run that made it one of the best-selling ATCs in Honda's lineup, the ATC70 accumulated a massive installed base that continues to generate strong demand for replacement and restoration parts. The simple air-cooled four-stroke engine with automatic clutch requires minimal mechanical knowledge to maintain, making it a rewarding restoration project for enthusiasts of all skill levels. Collectors and parents who restore ATC70 machines for the next generation find a solid parts ecosystem covering carburetor kits, engine rebuilds, tires, and cosmetic restoration components.

Popular Upgrades

The most popular parts for the Honda ATC70 include Keyster carburetor rebuild kits that restore proper fuel delivery on Keihin carbs degraded by ethanol or long storage periods, OEM-spec piston and ring sets for engine rebuilds on high-mileage examples, and replacement tires from Kenda and Carlisle in the correct ATC70 sizing that restore traction and appearance on machines with aged cracked rubber. EBC brake shoes restore stopping performance on the front drum, and replacement chain and sprocket sets in standard gearing refresh the final drive system on worn examples. Seat foam and cover replacements are popular cosmetic restoration parts for owners bringing ATC70 machines back to presentable condition.

Performance and Handling

The ATC70 uses leading-link front forks and a single rear shock in a simple setup that is straightforward to maintain and rebuild with basic tools. Replacement rear shock absorbers in the correct travel and mounting dimensions restore the ride quality that softens on aged original equipment. Front wheel bearings and the rear axle bearing set are common service items that should be inspected and replaced during any complete restoration to eliminate the lateral play that develops with use and age on small-displacement ATC platforms.

What carburetor fits a Honda ATC70?

The Honda ATC70 uses a Keihin carburetor in the 13 to 16mm range depending on model year, and a Keyster rebuild kit is the most reliable and cost-effective solution for carburetors that are gummed up or running rich or lean from aged jets and O-rings. Chinese-market replacement carburetors in the correct bore size are available as low-cost alternatives for severely damaged carbs, though quality varies and jetting adjustment is typically needed. For performance builds aimed at MiniMoto racing or youth competitive riding, larger bore Keihin or Mikuni carburetors with appropriate jet kits provide improved throttle response on engines that have been bored and built for performance use.

What tires fit a Honda ATC70?

The Honda ATC70 uses front tires in the 19x7-8 size and rear tires in the 22x11-8 configuration, which are available from Kenda, Carlisle, and ITP in both standard rib and knobby tread patterns. Rib front tires provide the best straight-line stability for casual recreational riding, while knobby patterns in both the front and rear improve traction on loose dirt and grass where most ATC70s spend their time. Always verify the rim size before ordering since some ATC70 examples have been fitted with non-standard wheels during past repairs that change the correct tire sizing.
