Since its inception in 1885, motorcycles have come a long way, with myriad changes and upgrades in design, technology, performance, and the convenience they offer. However, from time to time there comes a model that breaks all stereotypes that were associated with motorcycles and revolutionizes the field, making contemporary manufacturers rethink their models and follow the pioneer.

That being said, buyers are susceptible to wrong perceptions of motorcycles. While some remain underrated, others are wrongly celebrated. However, with time people tend to realize that these attributes, although exceptional, can lead to fatal accidents if not approached with restraint. People have come to call such motorcycles 'The Widowmakers', owing to the many lives that they have claimed. Some of these bikes are even difficult for experienced riders to tame. Although groundbreaking at the time of their release, they're nothing but trouble in the present times.

10 Suzuki TL1000 S

One of the most famous motorbikes to have existed in the scene during the nineties, the Suzuki TL1000 S was famous for its fondness for tank-slappers and unique buckaroo style of handling. However, a hidden problem made this beast of a bike quite unreliable when driven rigorously.

A rotary style rear suspension that was inspired by F1 racecars was fitted extremely close to the exhaust pipe, which resulted in the thinning of the damper oil, under heavy usage. This made the suspension under-damped and resulted in numerous accidents. This forced Suzuki to supplement the rotary damper with a steering damper in future models to save the TL1000 S from undergoing a terrible fate.

Honda's iconic Fireblade, the CBR 900RR became highly popular owing to the brilliant looks and incredible performance that it offered. However, this incredible performance was not everybody's cup of tea. Equipped with a light body that offered much faster handling than any of the liter bikes that existed alongside it, the CBR 900RR also featured a 16-inch wheel in the front that made the bike turn-in faster.

Although an experienced rider with proper knowledge in steering and throttle control can easily handle this magnificent motorcycle, it is not a ride that should be messed around with by amateurs.

Part of Kawasaki's legendary, yet cautioned against two-stroke triple series, the Kawasaki Mach III H1 500 made its entry into the market when the only relevant bike in its class-range was the Honda CB750. Weighing just 188kg, this monster was capable of producing 60hp in power output and reach a top speed of 125 mph.

This speedy affair coupled with the troublesome handling of a two-stroke motorcycle that has a weight bias on its rear-end made the Mach III H1 500 one of the scariest bikes that anybody could ride. However, it still retains its legendary status, owing to the fascination that two-stroke engines have had with motorcycle enthusiasts.

A dirt bike that was made famous by Kenny Roberts, after he raced the motorcycle to become the winner of Indianapolis Mile, Yamaha's TZ-750 Flat-Tracker is one of the most troublesome motorcycles that anybody can ever get their hands on. Even the seasoned and extremely talented Kenny Roberts swore to never ride this two-stroke, four-cylinder beast ever again, saying that he does not get paid enough to ride a machine like that.

Truth be told, he was paid exorbitantly at the time he made the statement, which makes it quite apparent how dangerous this motorcycle can be in the hands of an amateur. Good thing is that there are hardly any of these models left for purchase in the market, and the few that remain have been placed inside museums.

6 Suzuki TM400

Used to racing with the help of hand-made bikes, Suzuki launched its first production model of motocross open-class motorcycles with the TM400, which was released in 1971. Although promising to provide a whole lot of power, this motorcycle was quite a handful. Having below-par fork dampers and shock, the flexible frame of the bike featured awful geometry to make things really difficult for even an experienced biker.

This coupled with the strange ignition system, which advanced the bike's ignition on the basis of voltage output rather than the rpm made the TM400 even more unreliable. Bikers might be handling the motorcycle in the dirt and a sudden surge of power would come without any prior warning. There was no fixed point when this power would come, owing to the inaccurate ignition mechanics. The later models saw Suzuki fixing these problems, but the TM400 still remains one of the trickiest bikes to handle.

5 The Vincent Black Shadow

The Vincent Black Shadow! Doesn't it seem like a name that demands fear and respect? Well, so was the case when it was launched and people who have driven these maniacal motorcycles can testify to the frightening experience they guaranteed.

The Vincent provided shoddy handling and even poorer braking, courtesy its single leading 7-inch brake drum in the front, and a similar-sized drum in the rear. However, the Vincent engine seems to have never lost its charm.

4 Wheezer By E.J. Potter

One of the most extraordinary yet extremely dangerous motorcycles to have ever existed has to be the 'Wheezer', developed by motorcycle stuntman commonly known as the Michigan Madman, E.J. Potter. Made as a result of a strange idea and a drunken epiphany, the Wheezer is akin to no other motorcycle that has ever existed.

Struck with the concept that the Chevrolet engine resembled the Harley motor when seen from the rear and the only difference was that the former was a bit lengthier, Potter went on to create his fantastical customized bike on a Harley frame. The Wheezer initially featured a centrifugal clutch, which later got removed by Potter, since he had this idea that in order to promote a direct driving system he would have to abandon the clutch, thereby making it even more dangerous. Potter would race the Wheezer by revving the bike at around 7,000 rpm, while it rested on a stand and wheezing away by dropping it off the stand as soon as the race began.

3 Boss Hoss V8

A motorcycle featuring a 6,200cc 450 horsepower V8 engine should scream 'Scary' at the very mention of it, but that is not the only thing that makes this bike a handful to handle. It weighs in at over 1000 lbs, which hardly makes it nimble on twisty roads.

This powerful combination allows the bike to reach a top speed exceeding 160 mph and can even cause it to have rolling burnouts without the rider even realizing that it was happening.

2 Maico Enduro 685

The Maico Enduro 685 is probably one of the craziest motorcycles to have existed. Powered by a single-cylinder, liquid-cooled, 685 cc engine that is capable of producing a staggering 82hp, this two-stroke motocross motorcycle is extremely fast and scary.

This scare quotient is heightened by the fact that the bike only weighs about 200 lbs, and long-travel suspensions, narrow power-band, and short gears complement the attribute even further. Being extremely fast and tricky to handle, the Maico Enduro 685 requires not only a skilled rider but also a brave one to be handled properly.

1 Suzuki GSX R750

Irrespective of which GSX-R model a biker is planning to ride, if he/she does not respect the immense power that these Suzuki motorcycles are capable of producing, it could soon turn into a scary and traumatizing affair. However, with the GSX R750, the second GSX-R ever produced, riders were worried regarding the shorter wheelbase, thinking that it would prove to be a problem at high speeds and hinder proper handling.

Looking back at the same almost 35 years from its release, such a setting does not seem strange at all, but for bikers, at that time it was quite a radical change. These first edition models of the GSX R750 need to be driven like a proper sportbike and any hesitation or nervousness can prove to be fatal.
