Introduction
Light motorcycle market, the domestic excise tax abolished in 1989, reduced advantage for motorcycle liability insurance premiums in the revision and subsequent two occasions, 400cc class going to shift dramatically, further reducing the replicated received by the shrinking market, a new report the number peaked in '88 was on the decline. Also, a light motorcycle naked market, the market has decreased in recent years to change direction, and the 400cc race that had to be naked and, overwhelmingly 400cc market is also looking at the class composition is the share of this category.
However, V-TWIN MAGNA '94 years since the launch market is getting activated now, and also help ensure that growing genres and large scooter trend has turned stable.

Honda In view of these markets, while to maximize the benefits of motorcycles, light support you as your naked 250cc wide range of customers, and tears around the bike leg of a classless liter, while low rotation demonstrate the improved output characteristics Torukiresuponsu region, to achieve unprecedented Raidingufiru HORNET, and by turning off a strong impact as a model for light motorcycles market, this class will further strive to activation.

Aim of Development
In developing HORNET is the case today golden naked and custom categories, with overwhelming force and presence, is what you feel Raidingufiru realize the joy of a new bike, the more interesting people One of the points you wanted to go out.

Specifically, while maximizing the benefits of light motorcycles, the basic idea of ​​the Honda Neikiddorodosupotsu "PROJCET BIG-1" being followed, and so you feel more attractive to this wide range of people "Neikiddorodosupotsu Inpakutibu beyond class" concept, a sense of form and impact, aimed at the implementation of the new Raidingufiru.
The 250cc and which emphasizes the traditional strength of the surroundings by wearing leg break Waidorajiarutaiya powerful sense of class, such as by Monobakkubonfuremu adoption of the new design, exterior design provides a powerful intonation In it, two-wheel light / have the overwhelming presence beyond the frame of the motorcycle to embody HORNET.

HORNET concrete development goals are summarized as follows 4.
  1. Nyubaransudezain conscious of the impact can be obtained around the legs classless
  2. Response while maintaining a sense of stability and big bikes, Raidingufiru combines lightweight maneuverability of
  3. Torukiresuponsu needed to manipulate the wide tires riding
  4. Low-frequency sound and feel comfortable from the idling sound of a sensual 4-cylinder at high rpm
This, HORNET aimed at the "Nyuraidingufiru" is.

The 31th Tokyo Motor Show '95 [] in, they embody the prototype of the HORNET results, and could have a strong impact on traditional light motorcycles, many new values ​​as a naked received a favorable reception from the people.
Sports, hot, come touch.

Styling
Our decisions on styling the "riding in a fun, Tsutomu Sako some impact" in developing the theme, set out to defy the boundaries of the development approach of the traditional road sports naked.
First, the origin was adopted in pursuit of a wide tire styling. And look what the design elements introduced by the riding fun and wide tires, the important point to consider in determining the styling from here "conscious Nyubaransudezain foot surroundings," HORNET was born the concept of styling.

Getting the concrete design work from around the foot and impact conscious classless "Nyubaransudezain" to create. We also, 250cc engine, compact and powerful legs around in case an ideal vehicle for the glamorous body to represent the highlight of each other with each other and constricted part overhanging portion, a side view of the conventional method as well as design sketches, and sketches of Downview simultaneously from inception, made a thorough study of the styling. In particular, this Downview eyes stuck out because the bike rider came up. From the atmosphere, and also decided to Hornets HORNET = naming.

The mock-up stage, we see shapes that overlap in the sense of fine touch and actually extends over the palm, has perfected the design to achieve a slim and voluminous than originally imagined.
The volume from the fuel tank with a sense of right and left protruding Kuni Tsuyoshi, improves the design to arrive by foot sheet refined flowing lines, strongly narrowed towards the rear cowl and tail, placed in the bottom right The muffler was, an imprint Torukiresuponsu, HORNET in if you are trying to feel the beauty and functionality of design.

And by those brought about by the appearance of the intonation, though it has a strong impact on the image and running, maximizing function, HORNET in the [then] Nyubaransudezain was born.

Riding

Getting the riding season "250cc with a lightweight maneuverability, solid feedback Bikkubaiku" proceeded to develop theme.

Specifically,
  • In urban areas and ease of handling, combined with superior cornering performance on a winding if the realization of maneuverability in the 250cc sporty
  • Combines a sense of profound feeling moist stability, handling reminiscent of a certain Bikkubaiku telling banks also will be
To realize the two elements to this conflict with the pursuit for the following three points.

Adoption of wide tires
TireNimble and responsive handling that, to ensure stability for big bikes only selected radials.
Number of test results, 16 inches front (130/70ZR16) of the swinging, wide rear tire (180/55ZR17) by combining the traditional with the 250cc class was around the foot, the tire grip margin It became possible to achieve a sense of security by giving certain sense of stability.

Monobakkubonfuremu decisions (dimensions of finished vehicles)
Dimension
Dimension

Dimension, as well as reduce the load sharing of the front can advance the position of the head pipe, a high engine position by exertion of the roll direction "response and light" to determine the basic spec.



Handling in order to achieve a responsive and asked that match rigidity balance of rear wide tire. In particular, we improve the rigidity of the swingarm to improve torsional rigidity by a newly designed Monobakkubonfuremu adopted by the head pipe closer to the center than the center point of the conventional twist, moist feeling dimension was achieved with an exquisite balance of rigidity and stability of both.

For handling and feel the presence of anti 力感 around the rear body by adopting a different formula Pibottoburaketto bolt from the traditional monolithic frame, with the balance between structure and surroundings Reru frame and legs. In addition, by raising the rear wheel inertial mass, as well as seasoned and presence is felt around the rear tire and wide sense, to get around the presence and rear anti 力感, especially during city driving seat the comfort, the new structure Kusshondanpa also improve the tracking ability of a continuous winding (new pistons) is adopted, allowing for independent settings for each piston speed region.

The three points above, the conventional motorcycle taste new] [Raidingufiru been completed.















Riding the "big bikes with solid feedback and wide tires, 250cc compromise the position flexible lightweight maneuverability of the class," proceeded to develop the goal.

Specifically, in response to the wide tires manipulate, position and hold the handle in order to optimize the aperture angle of the handle'm degrees of freedom, do not put a 23 ° angle of aperture intentionally set.
The lower corners, lower corner 14 of the existing configuration that caused more than ° and has been riding with a high degree of freedom in the armpit and some little opening.

Seat position, the fuel tank fits extremely refined, step position, load and let the bank without difficulty, and with the optimal position and reduce fatigue.
These handles, seat position for each step that combines the lightness and aggressive, and set the optimum position can imagine the fun of riding.

In addition, may arrive on foot before riding regarded as a problem, is considered an important factor in setting seat height and seat shape a sense of security from the moment of boarding. In particular, when considering the demographics of motorcycles, light aimed at the legs get a sense of security may arrives Many riders.
Frame from the head pipe to Suinguamupibotto, by employing new design Monobakkubonfuremu connected by a single pipe, and one that can seat rails, seat width and profile design freedom it increased, and now it is possible to set the best seat shape.
Especially now, when the rider's feet land on the ground, depending on the shape of the inner thigh of the first sheet to interfere, they decided to focus on the angle of the foot on the ground, stick to this part of the sheet form thoroughly without compromising the design conscious body around the foot, leg arrived

Power unit is mounted on a CBR250F '86 year about 11 million debut at nine years, reliable water-cooled four-cycle four-cylinder valve DOHC · 4 249cm 3 engine-based, easy to handle in urban areas emphasis on the well to improve torque at low revs in order further to improve the sense of blowing Agari, closer to the peak torque peak power output characteristics and to have a torque curve upward sloping Ino Tsuyoshi .
Also, by setting a narrow valley of torque deliberately blown highlights Agari response "Torukiresuponsu" to feel characteristics.

Getting this season, especially the 4-output characteristics for performance-oriented feel and Agari
気筒Rashii blew a four series by a set, and set the specifications of each part as follows.
  • By coupling between each exhaust, speed and torque to achieve the aim (point A · B below.)
    In addition, as shown by shifting the consolidated position, # 1-4 consolidated low revs. # 2-3 aimed at consolidation of the torque speed range. In addition, the ideal choice to pipe size and hole diameter of consolidation
  • About 75% by squeezing the bottom of the exhaust pipe set, achieve the same effect as setting the long tube length. Maximum ripple effect (below C Zone)
  • By setting up longer than the conventional muffler tube length from the collective strength to achieve well throughout the torque completed Appumafuradezain

Finally, select the optimum gear ratio and ignition timing to take advantage of these characteristics, "Torukiresuponsu" completed the.

Getting the taste of exhaust noise, "a sensual 4-cylinder sound at high rpm and low frequency from idling comfortable," proceeded to develop the goal. Specifically, two points are summarized below.
Internal Structure muffler

And at low revs at idle, the goal of low-frequency sounds with a sense of comfortable weight against the traditional structure of three paths, reduced by two room structure with a chamber expansion chamber, the exhaust sound from the Kuni Kon exhaust sound source from the exhaust, with sound and a sense of weight.
In addition, in order to emphasize the sense of weight, the resonator chamber while eliminating the unnecessary internal muffler to register rolls, the outer tube of glass wool scarf, emphasizes the low frequencies by attenuating the higher frequencies.

In the medium and high revs, feel the power surge with a rise in the rotation for the goal line four-cylinder sound exciting and sensual. Specifically, exhaust, aims to optimize the resonance effect of the pipe muffler pipe length, change in sound quality was achieved by rotating the exhaust accompanied this rise.
In addition, by adopting the muffler, the exhaust sound of riding on, now sounds good to the ears of the rider to feel the change in sound and exhaust sound more exciting.

Brake
The braking system, "making the best use of a wide tire grip, braking stable braking force can be obtained" as a concept, the development proceeded.
Specifically, a single large diameter floating disc, by employing a combination of rigid-mounted four-pot, it is possible to unprecedented high oil ratio, as well as achieve better response and linearity, Disukupureto can improve the toughness of heat due to temperature change, brake systems and obtain a stable braking force, to achieve good braking feeling.
The brake pads yet at the excellent temperature stability of μ is obtained with high friction characteristics Shikatsu stable under all conditions, RC45 same type of Sintered (sintering) is adopted as the pads.
