When I was in 8th standard my brother have brought tvs Apache 150 in 2006-07. When I saw this bike I love the design of the bike it was awesome. From that year onward my interest toward bike started. Then when I was in class 10th the new Apache 160 was launched with new colure i.e. yellow. On this colure bike giving a beautiful looks and cuts over its body. When I first look the advertisement of Apache 160 I fall in love with it. From that moment I made a decision when ever I go for a new bike it is tvs Apache RTR 160.

On 2010 when my 12th board exam was being going to held. Then I talk to father about my new bike he said that if I get first division in 12th board exam then only he bring me bike only. From that day I have decided to work hard and bring my Black Panther (my Apache) home.

When my result came I have got first division marks. Then my father told me to wait of 3-4 month and decide which bike you want to bring home.

I have already decided which bike I want to ride. Months passes and I can't wait for my moment. In between those months I have surf on internet and read reviews of different bikes I regularly check the tvs Apache site regularly. Then on last week on November I have saw the Apache RTR 160 hyper edge was launched. Then I decided to take home only that bike with superb looks and style.

Then after waiting again for few months I finally got my hands on my new Apache RTR 160 hyper edge on 3rd of December 2010. It is an awesome bike to ride. When I first sit on Apache and started the engine it makes a very beautiful throttle voice and the looks on fuel tank the racing strip give it a awesome racing bike looks. It was a complete different experience on riding an
Apache.

The handling of bike is perfect but some says it leads to back pain it's not true I ride my bike daily about 12 km I don't suffer from any pain intact if I need a chance to ride Apache whole day I will drive it comfortably. But the tire grip of tier is little bit not satisfactory on wet roads. The breaks are good but the rear shock absorbers are not very good it give a bad sound when it gets to a big ditch.

The pickup of Apache is very good then those bike that I ride. The gear shift is problem for those who are new to Apache otherwise it is good. The average of my bike in city is approx 45 to 47 it is depend how you ride it. I am in lucknow I have got my black panther at price of 71,000. It is very good bike in compare to other bike which come in its segment as I suppose.

The vibration is still in this bike also but I treated as it is a feature of all Apache that are present. The tires are very good I found three times nail in my back tire but it never puncture till now I hope it does not happen in future also. There is a one problem in this bike is that it length the seat which is not very long in comparison to other bike except FZ.

The Split Grab Rails are very good looking it also give it a sporty look and one more unique feature is removal mud guard, the dollop attach in front of engine gives it sporty look and the unique design disc brake. The hyper edge is also come with rear disc brake with 2,000 rs extra but I have chosen with single disc brake.

Over all it is an excellent bike to drive. There are many more features present in Apache but this is all I have to say right now. And I am proud to be an owner of Apache RTR 160 hyper edge it is truly "it's now or never".

Regards,
Priyam Srivastava

Honda Develops 700cc Dual Clutch Transmission Engine

Posted: 26 Sep 2011 09:49 PM PDT


Original Source: Honda Develops 700cc Dual Clutch Transmission Engine from BikeAdvice.in

According to Honda Press release, Honda has developed a new 700cc engine for motorcycles. The engine has features like 700cc displacement with bore x stroke of 73mm x 80 mm, liquid cooled, 4-stroke in-line two cylinders and second generation Dual Clutch Transmission. The engine has powerful torque in low to mid speed range with top class fuel efficiency that too in most environment friendly manner. Honda claims fuel economy of 27 kilometer per liter (WMTC mode) which is best in 500 and 750cc engines. The engine also claims 40% improvement (according to Honda calculation) in terms of performance compare to other sports model in its class.

This new engine will see its way on three different models based on different concepts which will be showcased in exhibition at EICMA 2011 to be held in November in Milan, Italy. The engine has two types of transmission, a six speed manual transmission and 2nd generation Dual Clutch Transmission. A first generation Dual Clutch Transmission was introduced on Honda's Flagship model VFR1200F.

Honda claims that the second generation Dual clutch Transmission to be more compact, lightweight and fuel efficient.

The Honda press release has following main features of the new 700cc engine.

1. Higher combustion efficiency and lower friction

A wide variety of low friction technologies that aid better fuel economy are incorporated: To improve fuel efficiency through better-controlled combustion while realizing a powerful ride in the low- to mid-rpm ranges, the bore-stroke ratio is set at 73×80mm. An ideal combustion chamber shape and optimum valve timing also contribute to achieve stable combustion. Resin coating is applied to the pistons, and lightweight aluminum material is employed for the first time in a motorcycle in the friction-reducing roller rocker arm.

2. Uneven-interval firing and uniaxial primary balancer

Adoption of uneven-interval firing with a 270° phase crank and uniaxial primary balancer help realize an engine with a pleasant throbbing feel that also reduces vibration.

3. Branch intake port inside the cylinder head, valve timing

The layout of a branch intake port inside the cylinder head was chosen to have only one intake channel for two cylinders. This design creates deliberate interference between the two cylinders’ intake processes to achieve precisely calculated changes to combustion timing.
In addition, to change the valve timing between the two in-line cylinders with one camshaft, the specifications provide for a cam with two timing routines for the intake valve. Through these measures, subtle combustion changes can be generated to give the engine a delightful, pulsating feel.

4. Exhaust emission purification system

To maximize the efficiency of exhaust emission purification so that the catalyzer, a three-way catalyst, can be started promptly after the engine starts, the catalyzer has been placed directly beneath the exhaust ports. This design lets the combustion gas pass through the catalyst while the gas is still hot. In addition, a combination of measures, including the adoption of an electronically-controlled fuel injection system (PGM-FI)*3  allows the engine to achieve an emission level approximately half the European emission standards (Euro 3)*4 . The resulting environmental performance is ranked among the top in the world without compromising powerful, smooth output.

*3 PGM-FI (Programmed Fuel Injection System) is a Honda registered trademark

*4 Honda calculations

5. Second-generation Dual Clutch Transmission

The Dual Clutch Transmission, developed for the first time by Honda for motorcycles and installed on the VFR1200F, is now lighter and more compact through a simplified hydraulic circuit and other design enhancements. A learning function has been added to each selected running mode to detect a variety of riding environments from city streets to mountain passes and automatically performs the most suitable shift control. Although it is an automatic transmission, the Dual Clutch Transmission delivers fuel economy on a par with manual transmissions as a result of its excellent transmission efficiency.

Seems that Honda is aggressive on its Dual Clutch Transmission technology and in the next phase it will try to incorporate it in smaller capacity engine (250cc-500cc). It may possible that the next generation CBR250R engine will have Dual Clutch Transmission.
