[u]The Kinetic - Hyosung Comet 250</u>

The Comet 250 is here. That is all what you need to know. You might educate others as to how expensive it is and at the same time have an inner desire to have it. Or you might just go out one day and book it. Whatever the case maybe, you need to read the whole of this thing for you might be overtaking a Zen with this thing on the highway or you might get smoked by one on the highway.

One has to admit that the Comet is a Big bike, good power ( 27 BHP ), good meaty tyres ( isn’t that what most of us crave for ), and its an international ( if I may call it that ) bike. Its already in many of the world bike markets and there are forums catering to it.

So what does that mean to us ?

It means that the Comet that we will get will be a refined machine, because it has already been tested around the globe. One more fact is there that the Comet is priced cheap as compared to other world markets ( example : in some European countries its for 4990 EURO == 2.6 Lac INR ).


xBhp continues to be a step forward and now has the India's first Comet 250 forum for discussing about the Comet! Why go elsewhere when you got everything you want know anout the comet right on xBhp!

The forum is availaible here : http://www.xbhp.com/forum/forum.bike?FORUM_ID=79

Hope you buy a Comet, it is a gem of a bike!

Here are more details about the COMET, directly provided to xBhp by KINETIC:

[u]Hyosung Motors : Sometimes called the Hyundai of two wheels</u>

Korea has two major bike manufacturers - Hyosung and Daelim (like Hyundai and GM Daewoo for cars). Daelim portfolio comprises mostly obsolete Honda four-stroke single derivatives. Hyosung on the other hand is on a roll and is fast gaining reputation as a builder of well-priced and well-made motorcycles - even compared to the Japanese majors. Just what Hyundai has managed to do in the car world!

Hyosung Motors and Machinery Inc was founded in 1979 as an offshoot of Korea’s largest leather goods manufacturer. The company initially tried to tie up with a European manufacturer but turned its attention to Japan when Moto Guzzi attempted to palm off Benelli’s defunct production line. Production started off in 1980 at the Changwon facility with the FR80 step-thru and GP125 motorcycle. From the initial 15,000 units production reached a peak of 150,000 units in the mid ’90s all comprising bought-in Suzuki four-stroke singles.

However the deal with Suzuki prevented Hyosung from exporting their bikes which eventually led to the setting up of an R&D centre in Hamamatsu in Japan staffed by engineers poached from Honda, Yamaha and Suzuki. The V-Twin family of engines has been developed at this facility and are now the backbone of Hyosung’s expansion, especially in export markets (numbering over 40). From the initial 125 and 250cc V-Twins the range has expanded to include a 650cc V-Twin seen on the Comet GT650 and the Aquila 650. Engineers are working flat out to develop a 1000cc (and 800cc) V-Twin engine.

Kinetic has a technical collaboration with Hyosung Motors that has brought to India superstars like the Aquila and the Comet, as well as the four-valve sportsbike GF Laser 170.


Answering prayers of biking enthusiasts of India, Kinetic has launched the high spec, high performance sportsbike Comet 250. The Comet 250 made by Hyosung Motors, brings breakthrough technology and performance with its 250cc, v-twin, 8 valve, liquid cooled engine that gives 27 bhp power, 21 Nm torque and a top speed crossing 140 kph. The Comet 250, India’s only speedster, will take the motorcycles scene in India to a new level.

The first real sportsbike in India, the Comet is priced at 1.67 lacs (Ex showroom, except hyderabad where it is 1.63 Lac ex sh); and will be available only as a “limited edition” bike in select cities only. The list includes Mumbai, Pune, Banglore, Hyderabad, Chennai, Delhi+ NCR, Chandigarh, Kolkata, Guwahati, and Coimbatore.

Unlike Aquila, the number of vehicles for the Comet is not pre-fixed. The exclusivity of the limited edition will be maintained by restricting the availability to 11 cities, and by a timeline of only a month or so for the bookings. The bookings for Comet will close on November 20th, and so this will be the only chance to get hands on this exciting bike. There will be a 3-month delivery period after the bookings. The Comet will be supported by Kinetic in terms of after sales service and spare parts, in the cities where it is launched.

[u]Highlights of the Comet 250:</u>

• The large sized bike has a “naked sportster” styling inspired by Ducati Monster motorcycles and dazzles with its perfect proportions and a massive sculpted petrol tank. The Comet 250 will be available in three striking colors – red, black and yellow.
• The Comet features a very high tech 250cc, v-twin, liquid cooled, 8 valve engine (which uses roller bearing camshafts, chain-driven DOHC valve gear operating on four valve per cylinder heads and using dual squish combustion chambers for optimum volumetric efficiency and twin down draught Mikuni CV carburettors for fuelling )
• the Comet also features a high spec Suspension - meaty inverted forks upfront with a magnesium finish to the outer tubes and a monoshock rear suspension
• Rectangular steel cradle frame finished in silver chassis
• the most powerful brakes - 300 mm front disc, 210 mm rear disc
• 6 spoke alloy wheels finished in white
• Massive tubeless tyres (110 section up front and 150 section at the rear),electric start, etc.
• Standard electric start
• A sporty riding position that keeps most of the rider’s weight neutral and importantly off the wrists
• The Comet project initially started as a 250 and 650 based around the same cycle parts and hence (for the 250) every bit is oversized and over specced. Swing a leg over the Comet and she feels more like a 600 than a 250
• 1430mm wheelbase
• The differences in rim size (3-inch front to 4-inch rear) make for a quick turning bike
• The preload is adjustable on the rear suspension. The suspension of such mono-shock bikes can be set up for individual riders

[u]The Comet's Suspension by Ashraf Sheik. ( auto expert )</u>

The Comet 250 motorcycle marketed by Kinetic is as contemporary as any motorcycle in the world today. What this means is that it features state-of-the-art, technologically advanced systems that are commonplace on the best bikes all over the world.
The most prominent amongst these are the front and rear suspension systems.
For the user to truly enjoy the riding experience it is important for him to feel comfortable and safe on the motorcycle. And also to be able to fully exploit the potential of the bike, in terms of stability, cornering and braking.
The most significant contribution to achieve this comes from the suspension system.
The Comet 250 employs an inverted front fork and a mono-shock rear system.
The benefits of these two technologies can be easily understood when one considers that utmost rigidity is mandatory from the forks if good control is desirable from the motorcycle.
In the inverted type, the axle is attached to the smaller-diameter tubes, which slide inside the fixed tubes. This has the advantage of having the larger—and therefore stronger—tube connected to the steering head and clamped securely in the two triple clamps, much better than if they were attached just to the wheel axle, as is the case in conventional type. This reduces the amount of flex in the fork assembly considerably, allowing much more precise response to rider input. Besides this since the lower tubes are lighter on an inverted fork, this reduces the amount of unsprung weight and this too translates to a significant advantage. The less mass and inertia the shock has to dampen, the better it can do its job, which is to ensure that the tyres contact patch stays glued to the road surface.
To compliment this modern setup, the rear system keeps step by dispensing with the age-old twin shock layout. The mono-shock system as the name implies uses just one shock absorber at the rear in place of the two that were employed earlier. In fact, mono-shock rear ends are de rigueur on everything but old-style or inexpensive bikes. One of the main reasons for moving towards a single shock rear versus the twin shock design of old was developments in shock technology. The main drawback to running twin rear shocks was that it was very difficult to get both shocks to do the same thing at the same time. It is also more compact, lighter and cost-effective to use one shock in place of two.
To evaluate and appreciate the major advantages of the mono-shock system over the twin shock system needs an understanding of the workings of the two systems. In a twin shock system in the conventional position at the rear end of the swing arm the bottom ends of the shock absorbers, mounted at an angle move in an arc when the wheel encounters a bump or a dip in the road. This allows the spring and damping to operate efficiently only as long as the angle does not get too acute. When the swing arm travels more than the angle of the shocks can cope with the springs can no longer compress and are therefore unable to cushion the deflection. In fact the system becomes progressively softer as it nears the end of its travel. This is in exact opposition to what the suspension should be doing. The mono-shock overcomes this very efficiently. The shock absorber is mounted much closer to the swing arm pivot, thus allowing it to be mounted almost vertically, enabling it to maintain spring pressure through out its travel range. The shock, in the Comets case is working through a linkage which makes it possible to tune the entire range of its working to be compliant over the minor bumps and yet cope with the worse road surfaces without bottoming. This affords a much more comfortable and controlled ride, no matter what the road surface is. A further sophistication is that both spring preload and rebound damping on the shock absorber are adjustable. This makes it possible to arrive at an optimum setting for a wide variety of rider preferences.
Along with all this ride control comes an equally important feature; braking performance.
What good is it if you have a bike that can sprint down the road faster than anything you happen to meet on the road, if you cannot stop when and where you want to? The Comet 250 will not let you down in this department either. Equipped with adequate sized disc brakes on both ends, ensures that you can stop securely and speedily whenever the need arises. Even panic stops will not upset the balance as long as you combination brake with both brakes.
The Comet’s V-twin engine with its twin overhead cams and four-valves per cylinder configuration is a performance perfectionist and with the help of the faultless transmission will make faithful followers of anyone that test rides this one-of-its-kind motorcycle. And that’s not all with its broad-beam perimeter frame screaming stability, the Comet begs to be ridden and ridden hard.
And finally when you park it, make no mistake it’s the best looking piece of metal in the entire neighborhood

The comet

[bikefreak]

This is a really good step. But as far as I'm aware, u've missed 2 more threads (at least) that deal with the comet. Why don't u move them also into this fourm ? They are given below

http://www.xbhp.com/forum/topic.bike?TOPIC_ID=5346 &
http://www.xbhp.com/forum/topic.bike?TOPIC_ID=5587

Another suggestion that came to my mind. Why don't you close some of the threads as per your discreetion as most of them deal with similar issues about the comet ?

BTW, was the site down some time back for this purpose ?

[Sunny]

thanks for the follow ups! your suggestions are already on my mind. the site wasnt closed for this purpose.

[soulreaper_20]

awesome man ... BTW the comet wheelie looks awesaome... hope to see some of those in the near furure pals ?

[nfsnfs]
