then the movie “Chariots of Fire”, love of motorcycle friends is definitely a spiritual beliefs like existence, Andy speeding recall the scene in the movie, and now still make my blood boil. Andy Chariots of Fire – Honda NSR250R generation of young people dream of becoming models, their interpretation of the story is more exciting than the movies!
When NSR250R born, set thousands of pet in one, you can think of young, fashion, sports, passion, it can be used to describe it. Who would have thought it through a lot of variables before the birth, almost “abortion.”
When it comes to NSR250R without mentioning its designers – Paul Valley pool man, before formally joined the NSR project, which is responsible for Honda pedal car design and development work.
In this valley of the insurance pool male participation during the development of a water-cooled two-stroke, maximum horsepower 7.2 of sports scooter Beat, this car has a lot of different example : shock absorber with a front stabilizer, the front brake drum with a cooling air inlet, and the switching position of the foot pedal of the engine torque.
This movement 50cc scooters foot V-TACS system is controlled by the right of the Knights, but according to the prevailing vision insurance pool Valley man, but he is trying to do It means an automatic switching function.
RZ250
MVX250F
NS250R
NS250F
For the two-stroke engine , the Honda and Yamaha can not compete at that time, even the boss Honda – Soichiro Honda R & D team have expressed their own lack of knowledge and two-stroke engine technology. But also because of the respected Soichiro Honda four-stroke engines, two-stroke technology not taken seriously within the company. But in 1980, he launched a two-stroke Yamaha RZ250, to obtain a good market response, Honda also introduced a hurry to fight MVX250F sports performance and better NS250F / R and other models.
but the frustration at lack of two-stroke engine technology, these models can not shake the status of Yamaha RZ250. But also the emergence of various problems, at the time the image of Honda played a very bad influence, once cast doubt on Honda’s level. But these failures did not allow Honda to give up, but let them think that today’s failure would mean success tomorrow.
The time came at the end of 1985, when he was the designer of the Indian scooter market insurance pool Valley male, the company received the command appointed him NSR250R of total R & D director. To get a better understanding of the car, nothing beats himself rode around to the more practical, so the cold winter in the valley pool of security men, up the NS250R (NSR250R formerly) speeding on the track, with their bodies feel NS250R, draw their truest judge. As consumers reflect, he also encountered a vexing oil indiscriminate spraying, noisy and nasty problems such as noise, but one thing it touches on so he is quite satisfied that it really quickly.
RS250RW
to solve the problem NSR250R pool in addition to the Valley of the tireless efforts of security men, but also thanks to HRC sector, it is mass production market also played a crucial NSR250R role. HRC was established in 1982, although it is owned by Honda, but independent of the Corporation, the main function is to car design and development. And in 1985, while the pool man appointed Paul Valley, HRC factory team also identified the introduction of the car RS250RW, the news that Paul Valley pool man saw a shortcut to solve the problem. If there are data to support RS250RW design, then NSR250R within sight. But it did not, independent of the Honda HRC how hard could easily put information and knowledge technology research, commercial research and development team to tell it? For a research and development team, its own research and development of technology like their own children, do not even think you give it away easily.
Therefore, the pool man Paul Valley office the first thing is to keep a good relationship with HRC, and deeper deepen this relationship. As it is to learn more than technical knowledge of some two-stroke to resolve NSR250R technical problems.
In addition, he also Yamaha TZR250 other models conducted in-depth research to identify bright spots can learn from and improve their NSR250R. But this is not a simple imitation, is based on the original from the inside to the outside of sublimation and refining, which cover more than some domestic automakers housing is much more difficult.
NSR250R engine
Although the HRC was technical support, but want NSR250R production also face a problem that is the cost. RS250RW are excellent in all respects, but it is a sports car is born track, each body part to be processed in millimeters, removing all unnecessary parts, but also have been manually assembled by professionals at their best. As a result of its cost, naturally, it is very high, this is clearly not an acceptable commercial vehicles. But also in the design of the original intention of also very different, as the track for a born sports car, as far as possible the performance of the press, as long as the finish on it. While commercial vehicles will have to consider its durability, a user may not want to run fast, but ran near the car.
NSR250R the manufacturer chose Hamamatsu Manufacturing, HRC and its famous comparison, whether or precision technical strength to be somewhat more fragile, you want to create a RS250RW par NSR250R, there are still very difficult, this pool Paul Valley redesigned male mold, optimization details, feel close to Cleveland Speedway car experience at the same time, as much as possible to increase durability, and through stringent quality requirements carping , this has been the first generation born NSR250R MC16 1987.
NSR250R MC16
NSR250R MC16 using a 249cc two-stroke water-cooled 90-degree V-twin engine, the maximum power of 33kW 9500rpm, the maximum output torque at 8000 rpm for 35.3Nm, curb weight is only 141kg promote the body is simply a breeze.

NSR250R MC18 (P1)
in 1988, homeopathy introduced MC18 version than MC16 and It says it has increased the diameter of the carburetor, 28mm to 32mm increase from the original, and with a new generation PGM electronic ignition system. Engine compression ratio also increased from 6.2: 1 up to 7.3: 1, further squeezing out more power. And thanks to PGM generation electronic ignition system, this generation of models, also referred to the Friends of Mount P1. And in 1989, MC18 also introduced R5K and R6K models, both on the engine and other configuration the same, the only difference is that there is a R6K dry clutch.
At the same time, MC18 turn electronic ignition PGM upgraded to the second generation, of course it is, we often say P2.

NSR250R MC21
1990 to re-launch NSR250R MC21, which is the biggest feature appearance using gull rear swing arm, an exhaust back pressure chamber leaving a moreGood location. And the aluminum frame using the frame beam wings, to increase the longitudinal rigidity and the torsional rigidity at the same time, by reducing the wall thickness is slightly reduced transverse rigidity. Allow the vehicle to maintain a better balance high speed while driving.
It is worth noting that not all of the MC21 are P3! Because PGM third-generation electronic ignition system in 1991 was only fitted to the MC21, starring Andy Lau appeared in “Chariots of Fire” is in the MC21.

NSR250R MC28
after the introduction of generations NSR250R, appeared to be in 1994 MC28 fans NSR250R called the best ride, as well as we often say that P4. MC28 biggest change its electronic card key, so much that it is the key, than it is more appropriate to a decoder Some, under normal circumstances, its 40 horsepower horsepower, but if you insert a HRC a card, then it will output full power.
You may find MC28 is still using a shock before being vertical, in fact, tested Inverted damping in the development of MC28, but before Inverted damping stiffness too high and its “flexible frame” design concept does not match, it did not use.

to create a model is called the legend, not only have technical support, but also a persistent heart, and to pay unimaginable efforts can succeed, although not catch up with the motorcycle golden moment in the 1980s, but these legendary models, still can make people feel its former glory.
