Practically for the same reason your wife rearranges and decorates your living room, riders decide to customize their motorcycles. You want to fit it perfectly to your style. You want to adjust everything to its optimum performance and comfort. And of course, you want to get that uniqueness out of the design. Every rider likes to see heads turning after his custom motorcycle. It adds to the pleasure, and it just feels fantastic. You want to hear people say nice things about your kids, and it makes you happy to hear compliments about your two-wheeled beauty as well.

Custom motorcycle beauty

Building a custom motorcycle doesn’t only mean upgrading its performance and changing visual appearance. It’s also about adding to its functionality for whatever part it is missing from the factory. If you’re new to the hobby, you should probably start slowly. In the end, practice makes perfect, and you should upgrade your skills with time. Start with small changes and add simple mods (like the Smart Turn System or the Smart Brake Module ;)).

For some it’s a hobby, some do it for a living. Some just take it as a one time project, but in the end, most people would describe it as art. Are you having troubles to imagine how to connect dirty hands with art? Read on and see some beautiful custom motorcycle masterpieces as a result of dedication, hard work, great imagination and impeccable craftsmanship. Well, in some cases the creativity has no limits. It may not even have anything to do with art unless the art piece intends to bring a smile to your face. The video below certainly will.

Types of custom motorcycles

#1 Bobber

Custom motorcycle described as a »bobber« is called that way only in the last two decades, give or take few years. The name bobber derives from the word »bob-job« that riders use from the 1930s onwards, and it describes motorcycles customized in a way they resembled the racing motorcycle from the American Class C racing motorcycles back in the days.

The primary focus for this particular type of customization is to strip down any excess weight to improve power-to-weight ratio. Riders strip down all excessive fairings, remove the front fender and shorten the rear one, they remove any parts that aren’t essential for the best performance of the bike. One of the most recognisable features is the seat, only for the rider, a smaller gas tank, raised handlebars, and upwards curved exhaust pipes. This features became distinctive for this kind of custom motorcycles even up to date.

#2 Cafe Racer

Cafe racers started trending in the 1960s. The trend grew fast among young riders, which wanted to customize their motorcycles to resemble the Grand Prix racing motorcycles. Usually, Cafe racers were smaller displacement bikes, stripped down as much as possible to reduce weight and like with the bobber, to optimise the power-to-weight ratio. Riders tuned up the engines to the maximum extent practicable and upgraded their bikes for optimum handling on the road.

Another distinctive feature is the low-mounted and narrow handlebars, and elongated fuel tank, forcing the rider in a more racing position to minimise the wind resistance and getting the most speed out of their motorcycle. Custom cafe racer motorcycles were built for speed, not so much for comfort, thus they were intended for short-distance rides, like riding between cafes. It is obvious they were meant for showing off rather than riding. They are very trendy again in the last few years, and it is beautiful to see the return of the cafe racers on our roads.

#3 Chopper

Perhaps the most extreme custom motorcycle type, choppers are one of the most recognisable and undoubtedly the most popular type of motorcycles modification in the USA. It is not surprising at all, since the style originates from the USA. You just can’t miss them. You will quickly recognise this custom motorcycle type for their extended forks. Also, larger than the stock front wheel, increased rake angle and lengthened frames. Another signature feature of choppers is the so-called »sissy bar«. It is basically a set of tubes connecting the frame with the rear fender, very often set and extended several feet high.

Numerous workshops, also called »chop-shops«, are not only customizing factory built motorcycles but are building choppers from scratch as well. In many cases it became a type of an art form, sometimes risking a part of the motorcycle functionality and handling for a higher level of artistic expression. What started as a trend in smaller regions in the USA, soon became a worldwide phenomenon. The art form became popular after the year 2000 with many successful reality shows boosting this artform to an even wider audience.

#4 Scrambler

Scramblers are trending nowadays. Beside custom shops, even the manufacturers are releasing new models with scrambler designs, hitting tremendous sales results. The most recent scramblers the manufacturers introduced were the Ducati Scrambler, BMW R-nine-T and Moto Guzzi V7 Stornello Scrambler.

What defines a scrambler is the vintage, stripped-down design, knobby tires suitable for off-road riding, high pipes, rugged and aggressive looks. This type of custom motorcycle appeared along with the Cafe racers in the 1960’s where young riders competed in races from one point to another, often choosing shortcuts through rugged terrain and fields. Since back in the days there were no specific dirt bikes available. Riders customised the bikes available to make them perform better in off-road conditions.

Nowadays, manufacturers develop the dual-sport motorcycles to combine on and off-road riding experience. It makes me think if the latest Scramblers aren’t presented only for the riders who seek the visual attraction and nostalgia of this particular motorcycle type. As it seems, a lot of motorcyclists still have a lot of passion for Scramblers. Even among younger riders, recent Scrambler editions have a lot of success. Well, it has been an evergreen, and it will remain so for a while. Even though you can buy a Scrambler already from factory, a lot of riders prefer to build their own custom motorcycle in the “scrambler” look.

#5 Streetfighter

From my research, I could only conclude, that the Streetfighter type custom motorcycle evolved from the cafe racers as a subgenre in the late 1970’s to early 1980’s, after the introduction of affordable Japanese street bikes.

The rider removed as much fairing as possible to get the aggressive look. He took away the excessive rear footpegs, mirrors and perhaps some other unneeded details. One reason was to lower the weight of the bike and the second goal was to get the aggressive appearance that the name itself already suggests. Riders changed the headlamp as well, and it was trendy to add a big round one. Other mods were performance oriented.

One distinctive feature was to add the straight handlebars that helped to handle in wheelies. Another thing riders added was a short and loud exhaust. Better late than never, the manufacturers also recognised this trends. With a bit of delay, they introduced Streetfighters as serial production bikes. One of the first was the Triumph Speed Tripple, but the Ducati was the one manufacturer that went straight to it when Ducati introduced the Streetfighter in 2009.

#6 Supermoto

Supermoto is also called a supermotard. These custom motorcycles are created for races where riders compete on three different road surfaces that require different riding styles. Races take place on circuits with a combination of paved tarmac (road racing), packed dirt (track racing) and irregular jumps and obstacles (motocross). Supermotard, therefore, combines the characteristics of motorcycles from each racing type, allowing them to perform well on different terrains and different riding styles. Supermotards are usually custom motorcycles that combine an off-road bike with road racing tyres. Many manufacturers produce this particular combination in some specific models already from the factory as well.

Like with the Streetfighter model, Ducati went straight to it and had offered a specific motorcycle with a name that speaks for itself — the Hypermotard. Many other manufacturers offer dedicated motorcycle models for the same riding style, but Ducati has been the only one that chose a name that doesn’t allow many interpretations and sets the Hypermotard as a factory built Supermoto/Supermotard.

#7 Cutdown

A Cutdown is an expression for customization of scooter-like motorcycles. Most popular models for this type of custom modifications were the »Lambretta« and “Vespa” scooters. Whatever could the motorcycle still ride without was cut away, therefore the expression the »Cutdown«. Like with most other modifications, the number one priority is to increase the power-to-weight ratio and to get the scooter look as aggressive as possible.

Riders tuned up their Cutdowns with performance exhausts and modified carburettors, overbored cylinders and aftermarket shock-absorbers. They replaced the drum front brakes with hydraulic disc brakes as well and added a lot of carbon fibre add-ons to reduce the weight additionally.

#8 Drag bike

You’re probably familiar with drag races. Two vehicles are standing in line behind a ¼ mile stretch of asphalt with the goal to reach the ¼ mile mark as fast as possible. This kind of competitions are popular with a lot of different types of vehicles and motorcycles are no exception.

Custom motorcycle Drag bike

Racers modify drag bikes to get the most power out of the engine. Since they ride only in straight lines, customizers don’t put much focus on handling characteristics. Custom drag bike motorcycles are often elongated and have metal tubes extended far beyond the rear fender. This prevents the enormous torque to lift the front wheel and tipping the bike over. With modified engines with over 1000 HP, the acceleration is out of this world. Such power allows motorcycles to reach the ¼ mile mark under 6 second.

#9 Rat bike

Customizing a motorcycle can cost a fortune. But there is one specific type of custom motorcycle — the Rat bike. The basic idea of a Rat bike is to spend a minimum amount of money to keep it operational. Often without any consideration about the visual appearance. Riders of Rat bikes often use parts, that were not intended for the particular model of their motorcycle. Therefore they adapt any element to the point it serves its purpose. If there is a hole in the exhaust, Rat bike owners won’t weld it but would rather use a metal cover and fix it with clamps instead.

The rustier, the better. Some of the Rat bikes look like they came right out of the Mad Max series. They resemble motorcycles from the villains chasing Tom Hardy. While some riders find it awful, many seem to find beauty in rusty looks.
