How to build a cafe racer step by step A to Z
Thanks to technological innovation and a renewed emphasis on bad-ass aesthetics, this is a golden age for motorcycles. Any motorbikes enthusiast has, at one point, probably developed a taste for Café racers. These stripped-down two wheeled machines have changed the way we interact with motorcycles. Café racers tend to boldly emphasize on the philosophical statement:
In this article, we discuss how to build a cafe racer step by step.
If you fail to plan you plan to fail
Planning demands that you know the amount of money and resources you have to carry out your café racer project. Just like in a game of chess, the pieces you possess determine how easily you can capture your opponent’s queen.
Before you begin your project, take a detailed inventory of everything you need to complete your project vis-à-vis what you have at hand. Assess your commitment to the project and plan your expenditure.
Remember you will be spending an important amount of money to reshape your bike and that is why you need a budget.
You also need to put off unnecessary activities and instead focus your time and energy to the project.
Using our Game of chess analogy, sometimes you have to sacrifice the knight in order to capture the queen. These basic steps are compulsory considerations not unless you want to be one of those kids in a 1.6L Honda
Bike selection: The ultimate bike!
After you have planned the entire course of action, it is time to acquire the perfect bike for your project. If you are an amateur, you probably have researched much on how to build a cafe racer. That’s not enough. You need
there is a cafe racer in any bike…you just have to find it
Your café racer project will be all about
- cutting back on unnecessary clutter,
- improving handling,
- cutting weight
as well as
- unblocking potential horse power.
Knowledge, Time and Budget: The determining factors in a cafe racer project
Well at this point you need to consider three factors to guide you in acquiring your bike. These factors
Your initial decisions as well how your café racer will turn out to be in the long run will largely depend on these three factors.
You may have the money and the time but without the knowledge, your project would end up being incomplete.
Now switch any of those three factors around in the last sentence and the result would end up being the same.
There are many places to acquire the perfect bike for your project.
How would you like your bike?
This project will be all about giving out what you cannot keep
Planning your café racer project will not only save you time but also money and vital resources.
You need to identify the project steps that can be combined and those that need to
Planning will help you identify where resources can be shared and when they are needed. This will prevent a scenario when a certain part is needed and it is not available.
One more thing, you should cultivate a positive attitude towards the project as early as in this stage. Remain focused on what you want and avoid any distraction. As the saying goes: “You will catch more flies with honey than vinegar”
Set up the Workshop! Is it equipped?
Your workshop will be your working environment for the next couple of months. More often than not, the success of any café racer project is largely influenced by your workshop set up. Going back to our “game of chess” analogy, your workshop is your chess board. All activities will take place here. It is therefore important to ensure that your workshop has all
Tools and equipment should be carefully inspected and missing ones should be replaced. You need to know all the tools you will need to complete your project and purchase them way before you begin it. This is where you need to carry out the necessary research to identify what you need.
Make sure you have all what you will need in your project. For ease of accessibility, it is important to label the various tools and categorize them according to their purpose.
The workshop should be spacious and fully equipped. You should consider having specific locations for welding area/equipment, painting area/equipment, accessories, and a room or bench/desk where you will be doing the drawing and calculation of various measurements.
Disassemble the bike – Remove, remove and…remove
Before getting into the actual disassembly activities, be sure to note the delicate parts of your bike and designate a special spot for them.
The delicate parts of the bike will include the radiator(if any), the plastic fairings (they are worth good money if you don’t intend to put them back) and the gauge cluster. The radiator in most bikes is either liquid cooled or air/oil cooled.
Getting down to business-Separating the chaff from the wheat
Now that the preamble is over, let’s get down to business. The disassembly phase will require you to grab your camera and take tons of pictures before you begin unwinding those bolts.
A lot has been said on how to build a cafe racer but this section tends to be overlooked always.
Taking many pictures will help to document your build. You will also find it easy to reassemble the parts later on in your project.
You don’t want to lose vital parts of the bike.
You also don’t want a scenario where you replace the same part you removed from the same bike. This is where
As pointed out earlier in this article, building a café racer is all about cutting back on unnecessary clutter, improving handling, cutting weight as well as unblocking potential
Remove every part that requires replacement. You will have to take lots of photographs before and after removing every part. Ensure you store the part you have removed securely in your zip bag (here assorted heavy duty storage bags with zip-lock from Amazon). If the part needs modification for reassembly, ensure that is clearly
You may also opt to document every procedure, this will help to make your entire project clear and any hiccup can be traced. Consider having storage bins to store various parts. Your welding equipment should be on standby.
Frame cutting and welding, and lowering front forks
This stage requires that you
The rationale here is that building a café racer is an art much as it is a science and each bike is unique in its own way. Therefore, there
Frame cutting may sound to be a frightening title but it is one of the things you have to do to ensure that the end result is as solid and professional as possible.
It is important to take caution while cutting the frame. You don’t want to take too much off. Identify the easiest position to cut off the frame. This can be achieved by having a clear picture of how long you intend the seat and the cowl have to be. After cutting off the frame successfully, it is now time to weld a seat hoop.
We can now move to lower the front forks. This will accompany lowering the rear suspension as well. The desired effect here is to lower the
What to keep and what to ditch
This is the point where you will have to make genuine decisions on what to keep and what to ditch.
Anyone with proven skills on how to build a cafe racer will tell you that the ultimate appearance of your café racer will be determined by the modifications you will make at this step.
To start with, depending on your taste and preference, you will need to change your handlebars. More often than not, the first part that you will need to trash is the stock
Finally, you need to do a final touch on this conversion by deciding the mirrors to use. In most cases, the stock mirrors will end up in the dumpster. You will have to find some clean rear-view mirrors for your bike. To keep the profile of the bike low, many café racers builders opt for bar-end mirrors. You will also find a collection of lower clip
Another part that you may need to replace is the gas tank. There are numerous designs and styles of tanks.
You need to decide whether you will keep your original tank or use the tanks with side indents. Regardless of the choice you make, ensure that you take into account cable routing when replacing the tank. It is advisable to conduct this at the same time as the handle bar replacement as the two have a considerable effect on the overall length of the cables.
Fitting a replacement tank will no doubt require extensive engineering knowledge and expertise and if you are not competent enough in this field, then it will be wise to purchase a thank that is specific to your make and model. To protect your fuel tank from vibration, use rubber mountings whenever possible.
When it comes to the seat of your cafe racer, comfort comes last. The choice of your seat will depend on whether you intend your bike to carry passengers (or luggage) or not. If you intend to carry passengers, consider fitting your café racer with the seat that has a hump behind the rider. This is where the passenger would seat. Moreover, this extra space found in this hump is used to relocate the electrical wiring and you can use it to secure the battery if your bike needs one. Other seats are generally flat.
Now it is time to change the front fenders. Basically the front fenders for your café racer is usually shorter, lower profile counterpart or in some project completely removed. They need to be kept as light as possible. There are two options to achieve this. You can either opt to replace the front fender with a chrome one and the second option is to cut the original one. Doing so will make it light weight and will achieve similar results.
The wheels appearance also needs to be changed. You will have to decide how the wheels of your café racer will look like. You can choose to go with spoke wheel or alloy wheel. Either way, the ultimate appearance of your wheel will primarily depend on your taste and preference but should not be overlooked.
The stock headlights need to be replaced with classic ones. You cafe racer should have lights that will keep the track clear all the way.
Dealing with the delicate parts
In the process of building your café racer, there are parts that will need extra caution. These are the delicate parts that can ruin your project when placed in the wrong hands. This part serves to explain how to deal with these delicate parts. Who wants to ruin a project at this stage anyway?
Starting with the carburetor, you don’t want to be the guy who your boys wait for hours as you struggle kicking your bike for the 57th time to start. Nobody wants to be that guy. Nobody. That’s why you need to be extremely cautious with the carburetor. You need to choose quality filters, jets and needles that are going to be needed to rebuild your carburetor from the inside out
It is pretty much obvious that rejetting a carburetor can be a daunting affair. It can be real pain especially if you don’t have the right size of jets. However, rejetting is not a very difficult procedure and it can really help in the performance of your bike. Whenever you have difficulties with this part, seek professional help whenever possible.
Rebuilding the engine?
Most literature on how to build a café racer tries to avoid this section like a plague. However, there are instances when you will have to be forced to bite the bullet with an engine rebuild. This may be so when you are dealing with and old bike. Most bikes from the 70s are either tired or pooped out. In fact most of them are trashed. If you will rebuild your bike, you need to take great care as tampering with key parts of the engine can render your project incomplete. Some engines will not need to be changed.
The exhaust pipe needs to be changed as well. Do you need to use the swept back exhaust pipes? Are megaphones anything to consider? Well is all depends with your taste and preferences.
Now that said, let’s focus on suspensions. You need to spend on suspensions if you really want your café racer project to be successful. On this note, it is extremely vital to ensure that the dampening and the spring rates are matched to your weight and the weight of the bike combined.
When you lighten the rear shocks (eye-to-eye) you will get more cornering clearance and better turn in for corners. Lowering the back end of the bike on the other hand will not yield any improvement whatsoever.
Your ultimate bike will be cruising on two wheels. These wheels will determine the grip and stability on the road. They must therefore meet the standards of a café racer. The rims you decide to use must also be chosen carefully as mentioned earlier in this article. They will add up to the overall comfort of your bike.
The ignition system is yet another part that needs to be checked carefully.
This is the system that ignites the gas- air mixture as it enters the engine from the carburetor. This makes the engine to run.
You must take extra care when building your café racer, to have an accurate set up that time the exact times when the charging of electrical ignition coils to fire a spark plug at the top of the engine cylinder near the valves.
As opposed to the old setups, technology has come with better options and changed styles on how to build a cafe racer.
Brakes are an integral part of any locomotive. Café racers included. Your bike should have brakes that will make bike handling and steering easy for you.
Ask yourself whether you need braided stainless brake lines and new pads. If so, you need to acquire them.
When it comes to discs, you can swap out for larger discs from another bike. You can also opt to swap the front hub for something that came with two discs. At this stage, you need to ensure that you pick up a break master cylinder that is able to push enough fluid for two calipers. Take note of the steering head angle and triple clamp offset which feed to the “trail” part. We shall discuss this in details at a later day.
Preparation, rust off and cleaning: Pimp your ride!
Because you will be dealing with an old bike, odds are that it will be dirty. The older the dirtier. You
Look at the frames. Does the
Sometimes the parts you replaced might have rust. No one wants to ride a café racer stained with rust all over. If you find that the parts have rust, clean them.
You can sand where the paint is until it is gone completely. When the rust is gone and you are left with a bare metal, clean the area off with a solvent and dry it completely. Then get the paint of your choice and pimp your ride. Remember to use a clear coat to seal the deal.
You should take caution when cleaning the parts as it can turn out to be a messy affair if done
An ounce of prevention is better than a pound of cure
The most important part to clean is the tank. Using the primer to remove the rust is
Nonetheless, your tank should be stainless after the final coat. Why do you need to clean these parts in the first place? Well, rust is a chronic disease that has great potential to kill any metallic object it infects with no apologies. Just like other chronic diseases wears out your body, rust eats the stability of the metal slowly by slowly rendering it useless after some time.
The old saying comes true that an ounce of prevention is better than a pound of cure.
By cleaning the parts, you will be removing the rust that might have infected the metallic parts and by
Isn’t prevention better than cure? We shall discuss more on the cleaning of these parts later.
Everything is set. You have all the parts customized to your taste and preferences. It is time to reassemble the parts. This is where the café racer will take its shape.
At this point, you will need to use each and every picture you captured during the dis-assembly phase. The images will assist you to fix every part to where it belongs.
It is advisable to fix everything first before the seat. You don’t want to fix everything only to realize you missed an important component. You also don’t want to fix the seat only to find there’s something in the way later.
Always test if the parts fit before fixing them. It is not wise to fix something and take it off later because it didn’t fit well. As a matter of fact doing so will easily
You might have probably missed vital components in the reassembly phase. Talk of the brakes for example. Such a mess can cost you your life. You don’t want that to happen.
When you get to a point when you are assured that everything is in order, have one more check and boldly take the bike to the road. You now know how to build a cafe racer.
It is time to enjoy!
You have spent your precious time researching on how to build a cafe racer. You have spent hours building your own creation. You have sacrificed time, and money to have your café race customized to your taste.
Now is the time to enjoy the build as you prepare to enjoy the ride!
