Engine:

A four-stroke engine providing levels of performance equal to or surpassing its two-stroke
rivals, at a similar weight. The 249cc single cylinder revolution also brings with it a
significant reduction in pollutant emissions.
A SOHC water-cooled configuration and equipped with Honda's Programmed Fuel Injection system (PGM-F1)

 

ECU: the electronic injection control unit

The lightweight, simplified integrated injection system (PGM-F1) is yet another of the Cota
4RT's revolutionary technologies. With a lower volume than that of conventional carburetors,
it brings together in a single piece the throttle body and the ECU - its intelligent,
high-precision control unit.
Its sensors perform instantaneous calculations of a range of variables such as environment and
engine temperature, atmospheric pressure, etc., to ensure its optimal working and a precise
response anywhere, including demanding high-altitude conditions.

Battery-free starting:

Taking advantage of its R&D experience, Honda has launched a world's first:
a system in which the kick start activates an extremely high-performance generator that
provides the ECU with enough power to run the fuel injection pump, thus guaranteeing a
quick reliable start, eliminating the need for a battery feeding the electronic injection system,
and reducing weight.

Frame:

The introduction of a new engine has meant a complete redesign of the frame to bring it in
line with new requirements. The new aluminium twin spar frame surrounds the engine in a
diamond-type configuration, providing an optimal balance between rigidity and handling, as
well as perfect integration of the tank, the mudguard and the one piece muffler. Furthermore,
the weight/rigidity ratio has been optimised, losing 1.6kg without affecting performance.

Suspension:

Exclusive design from Showa both front and rear.

Front: 39mm cartridge-type fork with a special titanium nitrate coating, with 22-step
adjustable compression and 20-step rebound damping, 175mm axle travel.

Rear: vertically set gas chamber absorber offers maximum travel and gives lower centre of
gravity and reduced seat height, stepless compression and 12-step rebound damping
adjustment, 170mm axle travel.
