DESCRIBE A TOURIST ATTRACTION YOU ENJOYED VISITING
You should say:
• what this tourist attraction is
• when and why you visited it
• what you did there
• and explain why you enjoyed visiting this tourist attraction
Anyone who comes to visit my country should spend time discovering one of the most renowned tourist attractions of Vietnam which I’m going to tell you about. It’s a coastal city named Nha Trang.
It’s just a small city and you could walk around the city in a couple of hours but actually, there’s no need to do that as we have a fantastic public transport system. It really comes in handy so it’s easy to get around.
I visited this peaceful city one year ago when I was on my summer holiday. I came along the sandy beach to enjoy the fresh air, the refreshing breezes and the salty taste of seawater. I felt like my daily stress and hardness of life disappeared. I also dropped by some shops and chain stores in the centre but only for window shopping. Pavement cafes everywhere excited me most. There I could have a cup of coffee whenever I wanted.
I am definitely keen on this city due to many reasons. Firstly, it is such a worth-living city because of its peace, cleanliness and beauty. I can see the colourful lifestyles of the people there. Secondly, this charming city attracts a lot of foreign visitors, so I can learn many things from them, especially their good manners like queuing or bringing their own water bottle when going out. All in all, this is a city that is worth visiting once in our life.

By friend of a country, this time the second coming to the store,

The animation is the first appearance


It releases road sports motorcycle "VTZ250" to be able to enjoy willingly without the fairing
　Honda Motor Co., Ltd. releases it in 1984, and the road sports motorcycle which renovated improvement and the appearance design of an engine / the body / the foot circumference as a succession model of "Honda / VT250Z" getting a favorable reception by height of a simple style without the fairing and the general performance releases "Honda / VTZ250" from April 15.

　While the output / torque / the mileage improves general performance remarkably, this VTZ250 realizes large lightweighting (dry .152kg in weight → 144kg). It is it with the equipment that emphasized the lighter sports nature and the simple high efficiency road sports motorcycle which can enjoy a style and the interval when I was able to give you high feel of a material willingly inside and assumes that it is met still wider user needs from a beginner to a veteran rider.
　The engine thoroughly pursues the reduction of improvement and the frictional resistance of 吸 / the exhaust efficiency with two water-cooled .4 cycle / DOHC .90 degree V type cylinders which is the genealogy of the VT250 series (June, 1982 release). I can match the output characteristic of the inside / the low speed range to use many every day and improve 43PS /12, 500rpm, torque by the output while improving 2.5kg - m /10, 500rpm, the mileage to 52.2km/L (test 50km/h 定地走行 value).
　As for the visiting body / feet relations, a twin tube frame (a diamond type) of the light weight / Shin pull / amount of hardness and a product made in aluminum cast wheel (front and back 17 inches) of three spokes of the S character sectional structure adopt the front floating disc brake of the diameter (281mm) very much. I regard a refreshing style and the light sports nature as the equipment that I emphasized.
クニさんの友人、今回で2回目の来店、

動画は、初めての登場です

VTZ250は1987年に発売された、
VT250Zの後継かつVT250F（F2H）の廉価版という位置付けでカウルを無くし、フロントホイールをシングルディスク17インチ化したモデルであった。F2Hとほとんど性能的には変わらない上に、40万円を切るという価格設定（F2Hの8万円安だけでなくVT250Zの3万円安であり、後年はさらに値下げされた）を行なったことから、特にビジネスライダーからの評価が極めて大きく、当時のバイク便御用達車両として不動の地位を築いた。これによりVTZ250はかなりの台数が販売されたため、現在も愛用しているライダーは多い。

フェアリングのない気軽に楽しめる
ロードスポーツバイク「ＶＴＺ２５０」を発売
　本田技研工業（株）は、昭和５９年に発売し、フェアリングのないシンプルなスタイルと総合性能の高さで好評を得ている「ホンダ・ＶＴ２５０Ｚ」の後継モデルとして、エンジン・車体・足廻りの改良と外観デザインを一新したロードスポーツバイク「ホンダ・ＶＴＺ２５０」を４月１５日より発売する。

　このＶＴＺ２５０は、出力・トルク・燃費など総合性能を一段と向上させながら、大幅な軽量化（乾燥重量・１５２ｋｇ→１４４ｋｇ）を実現。より軽快なスポーツ性を強調した装備や、シンプルな中に高質感を持たせたスタイルとあいまって、気軽に楽しめる高性能ロードスポーツバイクとなっており、ビギナーからベテランライダーまで、一層幅広いユーザーニーズに応えられるものとしている。
　エンジンは、ＶＴ２５０シリーズ（昭和５７年６月発売）の系譜である水冷・４サイクル・ＤＯＨＣ・９０度Ｖ型２気筒で、吸・排気効率の向上と摩擦抵抗の低減を徹底追求。出力を４３ＰＳ／１２，５００ｒｐｍ、トルクを２．５ｋｇ－ｍ／１０，５００ｒｐｍ、燃費を５２．２ｋｍ／L（５０ｋｍ／ｈ定地走行テスト値）へと向上させながら、日常多用する中・低速域の出力特性もあわせて向上させている。
　車体・足廻り関係は、軽量・シンプル・高剛性のツインチューブフレーム（ダイヤモンド式）や、Ｓ字断面構造の３本スポークのアルミ製キャストホイール（前後１７インチ）、大径（２８１ｍｍ）のフロント・フローティングディスクブレーキを採用。すっきりしたスタイルと、軽快なスポーツ性を強調した装備としている。
