Honda Launches the New DN-01 Large Sports Cruiser with Innovative Automatic Human-Friendly Transmission
TOKYO, Japan, February 28, 2008–Honda Motor, Co., Ltd. announced that sales of the DN-01 large sports cruiser will begin in Japan on Friday, March 7. The unique, low-styling body features a liquid-cooled four-stroke 680 cc OHC V-twin engine that resonates power and a new automatic transmission, the Human-Friendly Transmission (HFT), that delivers superior throttle response for comfort even on long rides, and simple operation with no need for clutch use, allowing sporty riding.
DN-01
The DN-01 takes its name from the phrase "Discovery of a New Concept," after Honda’s desire to develop a new concept motorcycle. Since its exhibition as a concept model at the 39th Tokyo Motor Show in 2005, Honda has been working toward the market launch of the DN-01, efforts that resulted in the machine being exhibited at the 40th Tokyo Motor Show in 2007 as a model scheduled for release. The DN-01 was developed as a large sports cruiser materializing a new concept, equipped with distinctive HFT, which is based on the automatic transmission in the 1962 Juno M85 and features characteristics optimal for a production machine, thanks to continuous development and advances in electronic control technology.
Key Features
Powertrain
The liquid-cooled four-stroke 680 cc OHC V-twin engine featured in the DN-01 demonstrates powerful and flat torque characteristics in the low-rpm range as well as high-rpm range, realizing smooth and easy revving. A superb fit with the new HFT realizes a comfortable ride feel. A single-sided swingarm (Pro-Arm), acknowledged in the Goldwing and VFR, and a maintenance-free shaft drive with superior durability and quietness have been adopted for the drivetrain. The DN-01 design also takes vibration resistance into account with a full rubber mount for the engine. For environmental performance, the DN-01 conforms with the 2007 exhaust emissions standards in Japan with an electronic fuel injection system (PGM-FI*1) and a catalyst device (catalyzer).*1 PGM-FI (Programmed Fuel Injection) is a registered trademark of Honda Motor Co., Ltd.
Automatic Transmission
An infinitely variable hydraulic mechanical transmission, the HFT realizes the lightweight and compact configuration required for motorcycles. Compared with the V-belt automatic transmission used on scooters, this automatic transmission unit can be stored within the engine crankcase, increasing the level of design freedom in the body layout. The HFT responds to a wide variety of rider demands, from easy-to-operate, comfortable riding to sporty and nimble ride quality with a direct response to accelerator operation, due to the hydraulics and computer control. In addition to two fully automatic shifting modes—D mode to cover ordinary riding and S mode for a sportier riding experience—the HFT features a six-speed manual mode, which allows riding with a manual transmission feel. Moreover, the HFT equips the world's first*2 lockup mechanism for an infinitely variable hydraulic mechanical transmission, contributing to improved fuel economy during cruising.*2 According to Honda survey
Design
From the "Low & Long + Modern Organic Body" design concept comes a truly individualistic style. The long-nosed front cowl incorporates dual projector headlights with overall front face shaped in sharp image. The integrated muffler bringing about a sense of unity with the under-cowl, and the Pro-Arm swingarm supporting the rear wheel on one side to give the rear a simple look, as well as the ten-spoke 17-inch wheels, accent the machine's functional beauty and unique sense of style. The instrument panel design combines luxurious LCD and white LED to simultaneously improve visibility and significantly enhance owner satisfaction.
Brake System
The Combined ABS, which is a combination of the Combined Brake System and the Anti-lock Brake System (ABS), is equipped on the DN-01, delivering powerful and dependable braking performance.
The three-pot calipers of the front brake provides strong braking control, while rear brake is equipped as a foot pedal type bringing a sense of motorcycle feel. And with such features as a parking brake for convenient parking on hilly roads, the DN-01 provides a full range of functionality for a feeling of security.
Body
Centralization of mass and a lower center of gravity, together with an ideal front and rear weight distribution, ensure responsive handling even with the long 1,610 mm wheelbase. Large foot step boards that can be repositioned to meet rider preferences and a low 690 mm seat height make for a spacious and comfortable riding position, giving the rider the most freedom of movement as possible. At the same time, taking tandem riding into consideration, there is also plenty of room for a passenger on the wide and long seating area. Moreover, passenger and rider seats are close in distance to enjoy a conversation, and well-though layout provides wide-open forward visibility. As rider is, the passenger seat is also designed to deliver unity with the machine and feel the exhilaration of riding.
Body Color
To suit DN-01's unique styling, the four colors of variations are set, exhibiting a sense of luxury and complete satisfaction for its ownership: Pearl Sunbeam White, Pearl Amethyst Purple, Candy Glory Red and Graphite Black.
Other
The DN-01 features the Honda Ignition Security System (H.I.S.S.), Honda's unique anti-theft system using an electronic interlock. The device is programmed to start the engine when the IC chip built into the original key and the ID in the ECU of motorcycle matches. Otherwise, the system prevents the engine from being started, providing effective protection.
Furthermore, an original system has been established for the DN-01 to provide a higher quality service. This new system functions with DN-01 dealer information network to manage the service history of the customer’s machine. To reference authentication data of the machine from the network, the information is stored on a RF-ID which is built into the main key of its machine called, Honda Motorcycle Data (HMD) key. By showing this HMD key to the DN-01 dealer, the machine's service history and information are available instantly through this system, allowing Honda to provide even higher level of service that will also lead to a higher customer satisfaction.

Honda Launches Full Model Changes for the FORZA Z and FORZA Z ABS Scooters
FORZA Z FORZA Z ABS
Powered by a newly designed four-valve single-cylinder engine, the next-generation scooter realizes a powerful riding feel while complying with the 2006 Japanese motorcycle emission regulation. The new frame and suspension system ensure a more comfortable ride than before. Refinement of the overall body configuration, which includes modifications to the front meter visor shape and placement, results in an elegant form that realizes both increased aerodynamic performance and comfort. With the development concept "premium and comfortable two-seater," Honda has brought these models even further forward.
For the engine, a newly designed four-valve engine has been adopted rather than the two-valve engine of the previous model. Modification of the combustion chamber configuration, along with the adoption of metal crankshaft bearings and a new dual-core catalyzer have led to higher output in reducing vibration, and further improving environmental performance, including greater fuel efficiency.
The ever-popular Honda S-Matic automatic transmission now features a load sensing control system, the world's first*2 for a motorcycle, in addition to the seven-speed manual shift mode. By automatically selecting the shift position for optimal driving force to suit the riding conditions,the sensing system provides a powerful riding feel even on uphill roads or during tandem riding.
Since its market launch in 2000, the FORZA series has been well received for its sporty performance and superb utility. The 2004 full model change with the concept "stylish open two-seater" received high evaluation from customers and has been a long-time favorite, being as a top placement*3 for the number of light-weight motorcycle registrations for 37 consecutive months, from May 2004 to May 2007.

Key Features
Newly Developed Four-valve Engine
In the new FORZA series, the conventional two-valve engine has been upgraded to a newly designed water-cooled four-stroke four-valve single-cylinder engine. To reduce engine noise, along with metal crankshaft bearings, a sealed compact crankcase was adopted to ensure sufficient lubrication. With this sealed crankcase, it is the first time for Honda to equip a primary balancer shaft. On the environmental side, the engine makes possible one of the lowest fuel consumptions in its class*4,using a roller rocker arm and an offset cylinder configuration to reduce frictional losses, and adding an O2 sensor for optimized fuel injection control. The use of a newly developed dual-core catalyzer allows clean environmental performance meeting the 2006 Japanese motorcycle emission regulation while also guaranteeing high output, reducing vibration and contributing in superb fuel economy.

Evolved Automatic Transmission
In addition to the seven-speed manual mode, the Honda S-Matic automatic transmission installed in the FORZA Z and FORZA Z ABS now features a load sensing control system, a first for motorcycles. In automatic mode, the mechanism automatically determines the load from the vehicle speed, engine rpm and throttle opening, and automatically selects the gear that provides the optimal driving force for conditions such as uphill roads or tandem riding. This new system realizes a powerful riding feel even on hilly, winding roads.
High-rigidity Frame
The newly designed backbone frame consists of large-diameter, thin-wall, high-tension steel tubes. With the frame weight relatively unchanged, the new structure realizes a 60% higher lateral rigidity and a 30% greater torsional rigidity. Simultaneously tough and flexible, this frame offers improved stability during high-speed and tandem ride, along with comfort on city streets.
Elegant Styling and Design
The concept behind the design was "a solid body and emotional surfaces." The slimmer body and the minimal rear overhang emphasize a compact and sporty feeling. Through an overall review of the body design including changes in the configuration and placement of the front meter visor, the new styling achieves an elegant form with improved aerodynamic performance without compromising comfort. Asserting a sense of presence, the circular tail lamp inherits the image of the previous model, with an even sportier design. And with the instrument panel, the design offers a high level of quality reminiscent of an automobile.
Rich Variety of Body Colors
For new FORZA Z, simple but popular Digital Silver Metallic has been chose from previous model. Also, three new colors have been set for the FORZA Z: Graphite Black, Duke Magenta Metallic and Candy Tahitian Blue. For the FORZA Z ABS, two new colors, Titanium Metallic and Graphite Black, have been set for the body. Along with the body colors, seat and step areas are colored in mocha-beige, creating overall of two-tone colored body. With wheels painted in gold, FORZA Z ABS provides luxurious image.
