Honda DN-01

The Honda's stunning new DN-01 is in a class of its own—the world's first crossover bike.
The style like a sportbike, but offering Honda's radical new HFT Transmission, it's an automatic unlike anything you've ever seen. You can shift it into six preset ratios, or you can let it function as a stepless, no-shifting Constantly Variable Transmission, or CVT. The DN-01 is a perfect choice if you're looking to get into motorcycling or if you're just a long-time rider who wants to be on the most cutting-edge bike out there.

It's like no motorcycle you've ever seen. And it's definitely like no motorcycle you've ever ridden. The revolutionary Honda DN-01 is designed to create a nearly seamless connection between you and your riding environment, with a relaxed, low seating position and a clear view to the road ahead.
Its Human Friendly Transmission (HFT) allows you to ride in fully automatic mode, or you can shift it like a manual transmission via handy handlebar-mounted push buttons. You can even rev the powerful V-twin engine at stoplights, something most automatic transmissions won't allow.

The Honda's reputation for forging new categories in motorcycling takes its latest form in the radical DN-01. This futuristic machine combines true sporting performance with a fully-automatic transmission, a low seat height and exceptional style.

The Unique Features
- Powerful 4-valve, 680cc liquid-cooled V-twin engine.
- HFT transmission is a continuously variable, hydromechanical design that automatically and seamlessly changes drive ratios to produce strong, smooth acceleration. Unlike conventional belt-drive designs, HFT is compact, quiet, no scheduled maintenance, and features two automatic modes and a six-speed manual mode with push-button shifting.
- Low 27.2-inch seat height assures flat-footed confidence when stopped.
- Large-diameter 41mm front fork and single-shock Pro Arm® Rear Suspension (see Technology Section) provide a sporting ride on low-profile Z-rated radial tires.
- Combined ABS (LBS-ABS, see Technology Section) triple-disc brake system for sure-footed braking in varying conditions.
- Combined Braking System (CBS) provides excellent braking power for added confidence in a wide range of operating conditions. CBS applies front braking force whenever the rear brake is operated.
- On the DN-01, equipped with dual front disc brakes with three-piston calipers and a twin-piston rear caliper, rider application of the front-brake lever activates all six brake pistons in the front calipers. Application of the rear-brake pedal activates the dual pistons of the rear caliper and the center piston of the front-left caliper.
- Anti-Lock Braking System (ABS w/CBS) utilizes modulators- one each on the front and rear wheels- driven directly by specially developed electric motors. In operation, an Electronic Control Unit (ECU) monitors wheel and vehicle speed. If one of both of the wheels approach a locking condition, the modulators, via a signal from the ECU, lower hydraulic pressure by acting directly on the brake piston(s). As wheel speed re-approaches motorcycle speed, the hydraulic pressure is increased. This entire process is repeated numerous times in just one second, resulting in optimal braking pressure and enhanced rider control.
- Beautiful aerodynamic design provides protection from the elements.

The Engine/Drivetrain :
- Compact 680cc, liquid-cooled SOHC 52-degree V-Twin provides substantial torque and power for everyday commuting and spirited backroad riding.
- Programmed Fuel Injection (PGM-FI, see Technology Section) with twin 40mm throttle bodies and high-performance 12-hole injectors provide excellent throttle response and fuel economy
while contributing to low emissions.
- Auto enrichment system is integrated into PGM-FI to optimize the air/fuel mixture on cold starts and eliminates the need for a choke.
- ECU-controlled, closed-loop emission control system with oxygen sensor manage the air/fuel mixture and reduce exhaust emissions.
- Front-mounted radiator receives ducted air from fairing shroud to maximize cooling.
- 2-into-1 stainless steel exhaust system with chrome-plated triangular shaped tailpipe is designed to centralize mass for improved handling.
- HFT offers two fully automatic, infinitely variable transmission modes - 'D' (Drive) mode for ordinary riding, and 'S' (Sport) mode for sharper acceleration. In addition, a push-button-selectable, six-speed manual mode allows the rider to upshift/downshift with the simple operation of left thumb-activated buttons.
- The ECU-controlled HFT automatically 'downshifts' when climbing steep grades to maintain optimum power.
- HFT provides 'lock-up' in cruising mode for maximum fuel economy.
- HFT features button-activated mechanical neutral, permitting engine revving when stopped. Mechanical neutral is automatically engaged whenever the engine is turned off, allowing easy maneuverability.
