The Honda Express is a line of mopeds created by Honda between 1977 and 1983.

Variants include the Honda NC50 "Express", Honda NA50 "Express II", Honda NX50 "Express SR" and Honda NU50 "Urban Express". All versions of the Express line are powered by an air cooled 50cc two-stroke engine coupled to an automatic transmission.

Introduction

The Honda motorcycle corp. of Japan released the Honda Express (NC50) to the North American market in 1977. This new bike was designed to enter the large market for mopeds that developed following the 1973 oil crisis. As such it came with a fuel efficiant single cylinder two-stroke engine. It was also designed to be simple to operate, as many owners would be inexperianced with or intimidated by larger, more complex motorcycles. Honda accomplished this by using a fully automatic transmission and a small oil pump to self mix the Express's oil and fuel, thus eliminating the need for premixing.

Models

NC50

A 49cc Moped which was manufactured from 1977 until 1983, it featured an air cooled two-stroke engine. The versions from 1977 until 1980 had a manual choke, point's ignition and a spring starter. Versions from 1980 onwards included a kick starter, CDI ignition and automatic choke as well as an improved compression ratio. All versions include an automatic one speed transmission with a centrifugal Clutch, double suspension and forced lubrication (does not run on mix).

Restoration & Repair

Today many moped hobbyists have Expresses because they are reported to be reliable. There are numerous forums and websites on which shop manuals and repair advice can be found. Here is an article on Honda Express Repair.
