Riding for many years gives a rider the ability to know when they sit on a bad motorcycle. It also enables them to know when a bad-rated bike is hated for nothing. Unfortunately for the bike, whether a rider says it's good or bad, if the public hates a particular model, no matter how creative the commercials are, it'll still go down the automotive history as one of the biggest failures of all time.

This list features some of the biggest failures ever seen in the motorcycle industry. Some of these bikes are good and underrated, but others are a total disappointment. No one would want to sit on them for the second time after the first.

The H2 Mach IV 750 was one of the fastest motorcycles of its time. It was introduced in 1972. It was very fast that people nicknamed it the 'widowmaker.' Kawasaki said that the speed of the 750cc H2 Mach IV 750 required a seasoned rider with razor-sharp reaction.

The H2 Mach IV 750 accelerated from 0-60mph in 4.3 seconds. The biggest failure of this bike was its lightweight tubular frame that was too weak to contain the vicious performance of the H2 Mach IV 750's engine. It was upgraded in 1974, but it was still a dangerous bike.

The Indian Motorcycle manufacturing company started its operations in 1999 in Gilroy, California, United States. The company was operating in former CMC's operation facilities. The first model from the Indian facilities was the Chief, one of the most reliable cruisers money can buy. The Chief had a reliable S&S V-Twin engine – it was adored.

Unfortunately, Indian decided to build a brand new 1,600cc V-Twin engine called PowerPlus. This engine powered the Gilroy Scout. It was so bad that it ultimately caused the downfall of the entire company.

The Roadster 800 was introduced in 2000, manufactured by one of the oldest motorcycle makers in Germany, Sachs. The bike was equipped with an 800cc engine sourced from Suzuki, and it produced only 58 horsepower. The Roadster 800 was a conventional steel-framed naked bike with spoked wheels.

Although it was underpowered, it felt smooth to ride and handled pretty well, but it was priced very high. The fact that no rider wanted an underpowered bike with a racing motorcycle price made it a total failure.

5 1979 Honda NR500

The NR500 is known as Honda's biggest regret, the worst failure of all time. The bike was introduced when two-stroke motorcycles ruled the racing tracks, but it came with a four-stroke engine. Four-stroke engines are weaker than two-stroke, so Honda decided to develop their powerplant with 32 valves. And to improve its performance, the bike came with a monocoque body designed to reduce the motorcycle's overall weight.

Despite introducing an improved version with a V4 engine, the NR500 couldn't match its competition in performance and price.

Companies do innovative things to grab the attention of new buyers or maintain the existing ones. The F 650 CS or Scarver was a result of such ambitions by BMW. The company wanted to grab the attention of new buyers, women, and short riders.

They collaborated with Aprilia to build the 650 CS. BMW equipped this city commuter with a 650cc engine that was not very powerful. Its dashboard was too futuristic, and it was overly expensive. Its sales never left the basement, and BMW discontinued it after three years of production.

3 2012 Suzuki B-King

When Suzuki unveiled the B-King at the 2001 Tokyo Show, it was on fire. A wild concept of a stripped-down version of the Hayabusa hyper motorcycle. The bike featured a supercharger, a huge rear tire, and a styling straight from the future.

Everybody loved the B-King concept until it was produced. It had no supercharger, and its wild styling had been reduced to standard, yet it cost as much as it looked from the concept, a super naked bike. The absence of these features, which made people eagerly wait for it, meant no one wanted it anymore.

2 2018 Triumph Trophy 1200

Like many bikes in this list, the Trophy 1200 is not a failure because it's a bad bike. Triumph doesn't get a lot of things wrong when it comes to building incredible two-wheeled machines. The Trophy 1200 was launched in 2013, right after the 1200 Tiger Explorer.

The two shared several features, including the all-new 1215cc engine. Triumph was building the Trophy 1200 to compete with BMW bikes in the segment. The company had promised so loudly that it'd be a standout motorcycle in the cruiser segment. The failure was as loud as the promise.

1 2014 Honda CTX1300

The CTX1300 is a legend in many weird ways. It is the most recent flop in the motorcycle industry, and it also happens to be the one that gave up without a fight – it was produced for only one year. In a way, the CTX suffered a failure that could be reasonably explained.

First of all, this cruiser was based on the old STX1300. Straight off, no one expected the Americans to buy it, and they did not. On paper, the CTX1300 got style, but practically it was weirdly bland. Lastly, this bike was oddly equipped and overly expensive.
