Press Release, May 11th 1987, Imported and released the Italian sports bike "NS125R"

Honda Motor Co., Ltd. will import the sports bike "NS125R" produced by Honda Italia Industriale, a local production company in Italy, and will release a limited run (500 units) from July 1st .

The NS125R was developed for the European market, especially Italy, which has a long history of sports bikes. The series has been well received, especially among young people, for its light ride and sporty style, and in Italy in particular, it has been the best-selling on-road category for two consecutive years.

The engine is a water-cooled, two-stroke, single-cylinder. The cylinder, made by Giraldoni, has an inner wall coated with nickel and silicon carbide, giving it excellent wear resistance. In addition, it uses a Dell'Orto carburettor and a Solfer muffler/silencer to improve intake and exhaust efficiency, achieving an output of 22 PS/10,000 rpm and a torque of 1.7 kg-m/8,500 rpm, giving it powerful and sporty output characteristics.

Sales Plan (Domestic) 500 units (limited)

National Standard Cash Price 379,000 yen
(Excluding Hokkaido, Okinawa, and some other remote islands.)

The suspension is well-equipped with Grimeca cast wheels, front double disc brakes, Pirelli tires, and Marzocchi cushions. The body and exterior are made with Italian parts, including the Berlicchi frame, cowl, fuel tank, and headlights. The body is 2,000mm long, which is a little larger than the 125cc class, and is coloured in the image of the Italian flag, incorporating a rich Italian fashion flavour to meet the needs of users who want to express their individuality.

June 21, 1983, Press Release, Honda to release two new 80cc sports bikes with water-cooled, two-stroke engines: the Honda MBX80 Integra and the Honda MTX80R

Honda Motor Co., Ltd. will simultaneously release two new models on June 22nd: the Honda MBX80 Integra, a road sports bike equipped with a full fairing and a water-cooled, two-stroke, 79cc single-cylinder engine, and the Honda MTX80R, a lightweight land sports bike.

The engine installed in the MBX80 Integra uses a hemispherical combustion chamber with excellent combustion efficiency. Furthermore, it has a four-lobe reed valve with a baffle plate for smooth intake and a large exhaust chamber, resulting in a high output of 12 PS/9,000 rpm. 

It also has a well-established Pro-Link rear suspension that provides excellent road surface tracking, hydraulic disc brakes with dual piston calipers that provide high stopping power, and a full fairing that protects the rider from wind pressure while riding, making it a road sports bike with a full range of equipment suitable for the road.

The engine of the MTX80R uses the same hemispherical combustion chamber and four-lobe reed valve with a baffle plate as the MBX80 Integra. It has a high output of 11 PS/8,500 rpm and a tenacious torque performance at low and mid-speed ranges that matches the usability of a land sports bike.

In addition, the Pro-Link rear suspension provides excellent road-holding performance even on rough terrain, while the front suspension has a built-in fork mechanism and a long stroke of 200 mm. In addition, the slim body makes it easy to reach the ground, allowing you to enjoy a comfortable ride from rough terrain to urban areas.

The sales plan is

MBX80 Integra 3,000 units

, MTX80R 3,000 units (domestic, annual)

The national standard cash price is

MBX80 Integra is 228,000 yen

and MTX80R is 198,000 yen.

(Prices for Hokkaido and Okinawa are 3,000 yen higher. Other areas and some remote islands are excluded.)

June 20, 1979, Press Release, Honda releases MT50, a 2-stroke 50cc sports bike

Honda Motor Co., Ltd. will release the "Honda MT50" sports bike, equipped with a two-stroke engine, on June 27th. The bike can be enjoyed over a wide range of terrain, including not only city streets but also suburban areas and rough terrain. (Complies with 1979 noise regulations)

The Honda MT50 is based on the previously released Honda MB50, which was well received for its outstanding technologies such as a single-axis primary balancer, a bell-shaped combustion chamber, and an X-shaped backbone frame, as well as its innovative body design. It is a nimble sports bike equipped with large tires that provide excellent off-road performance, front and rear suspensions with good shock absorption, and handlebars with bars that are suitable for riding on rough terrain, making it a bike that can be thoroughly enjoyed both on and off-road.

Production plans are

The planned annual production volume is 62,000 units (including exports).

Standard cash price is

136,000 yen (excluding Hokkaido and some remote islands)

Honda's 50cc sports bike lineup now includes five models: the Honda CB50JX-I, Honda MB50, Honda XE50-II, Honda TL50, and the new Honda MT50. With each model having its own characteristics and ease of use, Honda is able to cater to a wider range of users.

Main features of the Honda MT50

engine

・Single-shaft primary balancer: A mechanism that uses one balancer shaft to balance the primary inertial force of the reciprocating part, reducing the vibrations specific to two-stroke engines.

・Combustion chamber centralized cooling cylinder head: The cylinder head is designed to concentrate more of the airflow around the combustion chamber while driving, effectively dissipating heat generated by the engine and reducing performance changes.

・Bell-shaped combustion chamber: Compared to the general hemispherical type, it has a greater effect on stirring the air-fuel mixture during the compression process, ensuring stable combustion from low to high speeds and preventing carbon clogging of the spark plugs.

・Separate oil supply system: Measures the throttle opening and supplies the ideal amount of oil according to engine speed.

・CDI ignition system = An ignition system that provides reliable ignition and improved starting performance, and is easy to maintain.

Body

・Heavy-weight concentrated design: Heavy weights such as the engine, fuel tank, and battery are positioned near the center of gravity, resulting in light maneuverability.

・X-shaped backbone frame: A simple frame constructed in an X-shape to reduce weight and increase rigidity, allowing for unique vehicle designs.

・Large diameter tires: The front wheels are 19-inch tires, the largest in their class, while the rear wheels are equipped with thick tires for driving on rough terrain, both of which are designed to improve off-road performance.

・Suspension: The car is fitted with a long stroke suspension of 135mm in the front and 120mm in the rear. In addition, the rear is tilted forward, which, combined with the wide tires, improves the car's ability to run on rough roads.

・Headlights and meter: Square headlights provide a wide illumination angle, and the highly visible speedometer and indicator lamps are integrated into the unit.

・Operability and safety: The turn signal switch, horn button, etc. are concentrated on the left side of the handlebar to improve operability. Also, safety is taken into consideration with a large tail lamp and turn signal lamp.
