スズキ・GSX-R（ジーエスエックス-アール）とは、スズキが製造しているオートバイのシリーズ車種である。
GSX-R250・GSX-R250R・GSX250Sコブラ

GSX-R250は、400（1984年）、750（1985年）、1100（1986年）と１年ごとに展開して来たGSX-Rシリーズの末弟として1987年3 月に発売された。新たに開発された水冷４気筒DOHC4バルブエンジンは、SPECと呼ばれるヨシムラデュープレックスサイクロンのOEMエグゾーストパイプを採用し、当時の馬力自主規制値である最高出力45psを14500rpmで発生し、丸目二灯というGSX-R伝統のカウリング（ハーフカウル仕様も存在した）を纏い、スチール製のツインスパーフレームを採用していた。当時盛んであったSP-Fレースを念頭にクロスミッションを採用したGSX- R250SPも1988年に登場した。

1989年2 月には、大径フロントディスク、アルミツインスパーフレーム、4連スリングショットキャブ（GSX-R250は2バレルキャブレター）、補強入りスイングアーム、前後ラジアルタイヤ（リアは18インチ）を採用したGSX-R250Rと呼ばれるモデルが登場し、GSX-R250と併売されるようになった。このGSX-R250RにもSP-Fレースを念頭に置いたGSX-R250RSP（シングルシートカウル、クロスミッション、調整式前後サスペンションを搭載）と呼ばれるモデルが存在した。

250ccクラスのレーサーレプリカモデルでは2ストローク車の人気が高かった事に加え、シリーズ中では比較的発売時期が遅く、いわゆるバイクブームの終焉とも重なり、GSX-R250、GSX-R250Rとも一度もフルモデルチェンジを受ける事無く販売が終了したが、GSX-R250のエンジンは後に発売となったアクロスの、GSX-R250Rのエンジンは後に発売となったバンディット250やカタナ250のベースエンジンとして、それぞれ利用された。

なお、GSX-R250Rの一部外装を取り外したコブラ（COBRA）というネイキッド車も廉価版の位置付けで1989年9月より販売されていた
GSX-R250 / GSX-R250R / a GSX250S cobra

GSX-R250 was released as a pupil at the lowest rank of the GSX-R series that unfolded every 400 (1984), 750 (1985), 1,100 (1986) and one year in March, 1987. I adopted an OEM exhaust pipe of the Yoshimura dupe Rex cyclone to be called SPEC, and four water-cooled cylinder DOHC4 valve engines developed newly occurred in 14500rpm in best output 45ps which was then horsepower self-imposed restraint value and wore a cowling (there were the half cowl specifications) of the GSX-R tradition called two circle eyes lights and adopted a steel twin spar frame. GSX- R250SP which adopted a cross mission appeared in the mind in a prosperous SP-F race in those days in 1988.

In February, 1989, a model called GSX-R250R which adopted large diameter front desk disk, Mitsu Al in spar frame, four consecutive slingshot cabs (GSX-R250, 2 barrel carburetor), entering reinforcement swing arm, front and back radial (the rear, 18 inches) appeared, and it came to be done GSX-R250 and 併売. There was a model called GSX-R250RSP (equipped with single seat cowl, cross mission, adjustment-style front and back suspension) which took a SP-F race into consideration in this GSX-R250R.

The release time was comparatively late and was piled up with the end of so-called motorcycle boom of the series, and sale was finished without GSX-R250, never receiving full model changeover with GSX-R250R, but, as well as the popularity of two stroke cars having been high in the racer replica model of the 250cc class, as for the engine of GSX-R250, the release and the engine of GSX-R250R of the across that it was it were used as release and bandit 250 that it was it and a base engine of sword 250 each later later.

In addition, the Ney kid car called the cobra (COBRA) which removed decoration partly of GSX-R250R was sold by the positioning of the cheap edition from September, 1989

CBR400F (Shebearl Ef) is a motorcycle that Honda Motor Co., Ltd. manufactured and was selling from 1983 to 1985.
Outline

The industry was receiving an unprecedented motorcycle boom the 1980's. It restyled to oppose the rival power of each company in only two years after it had put it on the market, and CBR400F was put on the market though HONDA had CBX400F in fierce battle district 400cc class. It is a model that is popular among the hot-rodder who queues up with CBX400F and the HAWK system and is HONDA now.
One type

CBR400F is one put on the market on December 20, 1983. Four DOHC4 valve of air cooling four cycles series cylinder engine that adopted rotational speed response type valve stop mechanism "REV" that changed from two valves into four valves on the boundary of 8500 rpm generated highest sale this time max power of 58ps/12,300rpm in the class and the max torque of 3.6kg-m/11,000rpm.

The body equips a double Cradle frame of the corner section pipe with NS Comustarhoel of 16 inches in the reception desk and 18 inches in rear. The brake became a general outer board from the Inn board disk, and was made the first piece one triple disk. Moreover, the chassis of the adoption of the adoption of the dual piston caliper and TRAC (brake torque response type anti diving mechanism) that had become compacter etc. was greatly strengthened from the former model. Moreover, the rectangular headlight under was equipped with large-scale oil cooler, and it became a feature on the externals side.

Two from which CBR400F Endurans was put on the market on May 31, 1984. It is a model by whom a half fair ring, under a caul, and two light type halogen headlight are added. Three that is put 4000 limited special editions on the market in July of equipping Endurans with full fair ring, and was called alias "F-3" from Cowling's character in addition.
Two types

CBR400F and CBR400F Endurans did the minor change, and became two types on August 31, 1985. The set made of the stainless steel tube muffler was newly adopted, lightening of the body each part was equipped at the same time, and it equipped it with the swing made of measurement aluminum arm and the spoke Cast made of aluminum three wheel. The exterior also abolished under a caul and it became a refreshing impression. Moreover, it is four from this model from which CBR400F formula 3 that installs the standard is added as for an expression single seat and an integral duralumin forge backing rear caul step.

It wiped, it did not cut, it was drunk by the wave of making to water-cooled, and handicap on the weight side transferred the road to CBR400R of the succession in July, 1986 though CBR400F had the performance not to be inferior of the water-cooled power of each company as super-air cooling sports at the HONDA end.

1 スーパーモタードで初となるVツインエンジンを独自に開発。そのポテンシャルはすでに海外のレースで多くの結果を残しています。７７゜Vエンジンはバランサーシャフトなしで単気筒エンジンよりも振動を抑えることが出来ます。また同様の排気量を持つ単気筒エンジンよりもコンパクト、軽量なエンジンはSXVのトータルバランスをひとつ上のレベルにします。すべてのエンジンカバーはマグネシウム製、バルブはチタン製と軽量化をさらに上のレベルまで引き上げました。クランクシャフトも軽量シングルピース。エンジン重量わずか３０Kgを達成しました。.


2 エンジンコンポーネント一つ一つも吟味された、最新鋭のものです。３８mmのスロットルボディー（５５０モデルは４０mm）、インジェクション、プログラマブルECU,　駆動伝達部分も最軽量のものを使用、今までない最新鋭スペック、コンパクト、かつ軽量の駆動部分を達成しました。


3 フレームはエンジンと共に開発され、フレームとエンジンが共にマシン剛性を高めます。中空スチールトラス構造にアルミ製サイドプレートが高い剛性とねじれ特性を生み出します。


4 アプリリアのお家芸、アルミ製スイングアーム。軽量はもちろん、高い剛性を持ちます。スーパーモタード特有のワイドタイヤの装着にも対応。6.5インチ幅のタイヤの装着が出来ます。その際にチェーンとの干渉を防ぐため、エンジンに延長ドライブシャフトを標準装備、フロントスプロケットを外側に動かすことでリアのスプロケットに合わせることができます。
1 I develop a V twin-engine becoming naive in スーパーモタード originally. The potential has already left many results in an overseas race. 77 ゜ V engines can hold vibration in check than the one-lunger without a balancer shaft. In addition, a compact, the lightweight engine do total of SXV of balancing in a level in the one than the one-lunger with similar displacement volume. All engine covers were made by magnesium and raised lightweighting to an upper level if the valve was made by titanium. Single peace lightweight as for the crankshaft. I achieved engine weight few 30kg. .


2 It is the latest thing that one one engine component was examined closely. A throttle body (550 models, 40mm) of 38mm, injection, the programmable ECU, drive transmission part achieved the few latest specifications, a compact and a lightweight drive part with the most lightweight thing so far.


3 The frame is developed with an engine, and a frame and an engine raise machine hardness together. A side plate made by aluminum is twisted with high hardness for hollow steel trass structure and brings about a characteristic.


4 A swing arm made by a specialty of the application rear, aluminum. Not to mention light weight, I have high hardness. I cope with the wearing of a wide tire peculiar to スーパーモタード. The wearing of the tire of the 6.5 inches width is possible. An extension drive shaft is supplied with it to an engine to prevent interference with the chain and can put it together to a sprocket of the rear on this occasion by moving a front sprocket outward.
