Welcome to Honda moped parts and info. There is more info here than parts for sale. Most Honda Parts for sale are in the Parts by Type menu. Honda mopeds and the parts for them were only sold through Honda motorcycle dealerships. So the small shops that sold parts for European mopeds never did have genuine Honda parts in their inventories.

Myrons carries Honda parts from four sources. 1) aftermarket parts like brake shoes, spokes, tires, tubes, batteries, bulbs, petcocks, bearings, seals, hardware, spark plugs, etc, 2) some original used Honda parts from a few stripped out used bikes, mostly NC50. 3) Honda-Japan compatible parts from Taiwan-made Honda remake mopeds.  4) Honda-Belgium compatible parts from other European made mopeds.

Honda Belgium: Honda expanded it’s production into Belgium in the mid 1960’s, after the successful Honda 50 Cub sold well worldwide. Around 1975, when parts were also produced in Netherlands and Luxemburg, the name changed from Honda Belgium to Honda Benelux (for Belgium, Netherlands, Luxemburg). Since the 1950’s Europe had a demand for pedal-assist mopeds. 

Honda Benelux mopeds: Honda Benelux produced the P50 pedal moped from 1966 to 68. They made the PC50 moped from 1969 to 77. See the Wikipedia Honda P50, and Wikipedia Honda PC50 articles. Honda Benelux also produced the PF50 and PS50 families. The successor to the PC50 four-stroke 1-speed moped was the PA50 two-stroke variable speed, with way more take off and hill climbing power. The PA50 was produced by Honda Benelux from 1976 to ’91.

1. US Models   50-110cc   1959-84

 

 

 

 

 

 

 

 

 

 

 

 

These are condensed from the Honda Identification Guide 1959-2000. Over 110cc models are excluded. Pure off road and 3 or 4-wheeled models are also excluded.

The pedal-assist models that U.S. Honda dealers sold were the P50, PC50, and PA50. The two-stroke Honda PA50 moped is made in Belgium, and is covered in the Honda Benelux section. The 4-stroke P50 and PC50 mopeds were only sold one or two years each, and are not as common in the US as they were in Canada and Europe. The US motorcycle laws were not favorable to pedal-assist mopeds (motorized bicycles) until 1976.

Honda made many step-thru models that were like mopeds. They had foot shift 3-speed 4-stroke engines, but no manual clutch. So they were easy and well mannered compared with the roaring two strokes and bigger bikes. Honda revolutionized transportation worldwide with the C70 step-thru motorcycle, and set a Guiness World Record for the most motorcycles ever made of the same model. Ordinary poor people could go places cheaply reliably and safely on a Honda. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

In the next few years after 1984, for street bikes below 120cc, Honda only made scooters. Scooters have a rear engine, and many things different from mopeds. The only parts for 49cc scooters that Myrons might have are brake shoes, spark plugs, batteries, mirrors, and other things, but not much else.

In 1985 Honda came out with the Elite line of four stroke scooters, with continuously variable automatic transmissions. Once again forward-looking Honda revolutionized transportation. Before the Honda Elite there was no such thing as a 4-stroke scooter. Five years later, in 1990 Japanese scooters (Honda and Yamaha) were fairly common in US cities. Twenty five years later, in 2010, Chinese four-stroke scooters were as common as motorcycles on American city streets.

The first digit of the PC50 frame number changed from 1 to 2.

Honda PC50 Parts:

Tires: front 2-ply 2.00 – 19, rear 4-ply 2.25 – 19

Some of the parts on an early 1970’s PC50 are found on late 1970’s Taiwan mopeds that “copied” Honda. Myrons Mopeds has these PC50 items:

Engine parts 90% the same as Indian. See Parts/By Brand/Indian

Hubs & 80mm brakes 80% the same as  Angel

Cantilever Fork & suction cup solo seat 80% the same as Angel

Levers/switches 80% the same as Indian/Angel/General, maybe

Cables and other things might also be the same.

Tail light looks like Angel tail light

4. Honda NC50, NA50, NU50

Before the scooter craze of the late 1980’s, and during the end of the moped craze of the late 1970’s, Honda offered an ultralight kickstart moped, without pedals but still speed limited to 30mph. Thousands of NC50 Express and NA50 Express II mopeds were sold in the US, especially in states that did not require drivers licenses. Honda ran magazine ads showing how silly and ridiculous the obsolete pedal-assist mopeds were, and how a Honda Express would zip by them on the uphills.  

 

 

 

 

 

 

 

 

  One Speed Models:

1977-81 NC50 Express

1979-80 NA50 Express II

1982-83 NU50 Urban Express

 

  Two Speed Models:

1981 NA50 Express II

1982-83 NC50 Express

You can tell a two-speed by the bulge on the transmission cover.

 

 

 

 

 

 

1982 Honda NC50-AA Express Iowa
25mph version, not 30, for Iowa and other US states
has a restricted cylinder (on right, normal on left)
has a restricted carb PA25A-A see Keihin for details

 

 

 

 

 

 

 

Honda Express Parts:

Gas tank: The gas tank and oil injection tank are one unit. Often the wall between them leaks, allowing gas to get into the oil and oil to get into the gas. The simplest fix is to drain the oil tank and block off the supply line. Then use pre-mix 50:1 gas and oil.

Gas valve: M14-1.0 spigot down, see Gas Valves

Gas cap: 30mm quarter-turn, see Gas Caps

Carburetor: Keihin 11.5 mm, see Keihin where there are many photos, illustrations, and much information, as well as Honda Express carburetor parts for sale.

Main switch: Substitute main switch, fits and functions the same, but has 4-wire plug, price $20 with two keys

 

 

 

 

 

 

 

Spark plug: NGK BP5HS or equivalent, see Spark Plugs

Tires: 2.25-14 front and rear (NC50, NA50), see Tires

5. Honda PA50 Hobbit/Camino

The Honda PA50 pedal moped was produced at Honda Benelux from 1976 to 1991. The PA50 was called Camino in Europe, and Hobbit in the US. The PA50 Hobbit was sold in the US from 1978 to 1983. See the Wikipedia Honda PA50 article for more. Honda PA50 parts were originally only sold at Honda motorcycle dealerships, never at independent moped shops. Some components are interchangeable, or available for, or from, other European moped brands.
