Top Ten fastest bikes in the world

10. Suzuki GSX-R750

On the number 10 spot is not a liter class bike but a 750 cc bike, the Suzuki GSX-R750. In 1985, this was the first bike which started the trend of sports bikes and later on super bikes. The 4 cylinder 3/4th liter motor develops 148 Bhp of surging power. This power combined with its light weight chassis ensures that the Gixxer reaches its top speed of 268 kmph really fast.

9. Ducati 1098S
Number 9 spot is taken up by the Ducati 1098S. When this bike was first revealed to the public in 2007, there was a frenzy of fans for this bike. This was the ideal machine for both the race track as also for daily road use. This Italian bike also boasts of having one of the highest power to weight ratios across all sections and road going bikes. This bike boasts of a top speed of 275 kmph from its 160 Bhp motor.

8. Honda CBR1000 RR
Number 8 space is occupied by the Honda CBR1000 RR. This bike was introduced in the year 2004 and the designers are none other than the ones who have built Honda’s Moto GP bikes. A 1 liter 4 cylinder liquid cooled engine does duty on this Fireblade enabling it to push out 178 Bhp. With all this power, the Honda could go only 1 kmph more than what the Ducati could do. However the Honda revved to a very high 13k rpm.
7. MV Augusta F4 R312
The MV Augusta F4 R312 is number 7 on our list and it is here for a good reason. Not only was this bike meant for racing purposes but it is also built with the intent of taking a lead in all the races that it participates in. It makes a cool 182 Bhp at 12,500 rpm. The top speed that one can muster on this Italian is 282 kmph.
6. Yamaha YZF- R1
On the number 6 position is the world famous Yamaha YZF- R1. This bike was a rage in 1998, the year that it was introduced and still is. The liter engine has got 16 valves with 4 cylinders and liquid cooling technology. Not only does the Yamaha achieve a top speed of 284 kmph but it also does 0-100 kmph in 3 seconds, just 0.1 seconds off the official timing of a Lamborghini Aventador.
5. Suzuki GSX-R1000
For the number 5th position is another Japanese, the Suzuki GSX-R1000, the bigger brother of the 750. While the R1 may not be attractive to look at, the Suzuki is one hell of a looker. Its 999 cc liquid cooled motor makes 192 Bhp of power at 12,100 rpm and this is enough to propel this bike to a top speed of 285 kmph.
4. Kawasaki Ninja ZX-10R
Another Japanese slots in the number 4th position and this time it is Kawasaki making their debut in this list. The bike is the Kawasaki Ninja ZX-10R. From its ram air induction technology and 1 liter engine, this Ninja produces 198 Bhp of power which is more than enough to take this bike to its designated top speed of 288 kmph. As far as its desirability goes, this bike has quite a reputation of getting stolen and has the most claims for theft insurance.

3. Kawasaki Ninja ( Ninja ZZR1400)
The most powerful Kawasaki Ninja, the Ninja ZZR1400 makes its debut in the number three position. From its 1400 cc engine, this bike develops 190 Bhp of power at as low or high as 9500 rpm. This is enough to propel it to a top speed of 300 kmph and at the same time racing from 0-100 kmph in only 2.8 seconds.

2. Suzuki Hayabusa

We are sure that all of you guys must be wondering where the Suzuki Hayabusa, the legendary motorcycle, would be. Well, here it is at number 2 position. It also has a reputation of being the most powerful bikes in production across the world. Superbikes cannot get more maniacal than this and the Hayabusa has proved it time and again. As of now, this Busa does 302 kmph top speed runs however earlier on, some of the stock Hayabusas were seen clocking 325 kmph on a regular basis. Suzuki had to restrict its performance as it was seen as a death machine by many.

1. BMW S1000RR
The BMW S1000RR. If you would have noticed, the battle for the top spot was always fought between Japanese however it is an unsung German which finally clinches the top honors. Various Motorcycle of the Year awards plus Machine of the Year tags means that this radical looking motorbike is one of the best in the industry. It produces 193 Bhp of power at lofty 13500 rpm and its top speed is in the regions of 306 kmph. Its performance is enhanced to a great effect by its 181 kgs dry weight. Its radical styling may not win it many fans but it is the fastest stock production bike in the world as of now.
