Brembo brakes help sell motorcycles by demonstrating that the manufacturer chose a premium component for their machine. But how did the Italian brake company become such a renowned brand in the motorcycle world?

Finally, Harley-Davidson Big Twin engines with variable valve timing (VVT) have been introduced on the new 2023 Street Glide CVO and 2023 Road Glide CVO models.

We'll tell you about the main new features of both models, which also include new fairing designs and improvements to the suspension and infotainment.

In collaboration with Chinese company Qianjiang, Harley-Davidson is about to launch two new mid-displacement models: the X350 (HD350) and X500 (HD500).

Both models take the engine and many of the parts from the Benelli...

It seems that not everything is finished for the legendary Sportster model. The SWM brand has created a "clone" of this motorcycle, presenting a prototype at the Milan EICMA show very similar to what the commercial model will be, which could arrive at dealerships in September 2023. Its characteristics are...

One of the most important parts of the motorcycle, where the rider directly interacts with the machine's power control, is the throttle.

Can you confirm with certainty that your throttle is correctly adjusted? When you open the throttle grip to the full throttle, is the throttle actually fully open?

In this tutorial, we'll show you how to check and adjust your throttle in 6 steps.

Transmission oil must protect the gears and clutch plates while facilitating smooth and precise gear shifting. We'll explain how oil performs these functions and what qualities are essential in its formulation...

This engine marks a very important milestone in the brand's history, as it is the powerplant that will be used in most new models in the coming years.

Let's review the most distinctive features of this engine, both compared to other Harley-Davidson models and other similar options from the competition...

If you're a mechanic, you've probably read in a manual more than once about procedures for using the tightening torque for a nut or bolt. You might think you don't need a torque setting to change spark plugs or retighten exhaust bolts. But statistics show that bolts are often over-tightened, leading to breakage and damaged threads.

In this tutorial, we'll try to explain in a simple way what torque means, what it's used for, and how to check it...

A vehicle's transmission or gearbox allows us to modify the rotational ratio between the engine's crankshaft and the rear wheel. This ratio is called the "ratio," and to put it simply, it works the same way as...

Is your engine's high end generating too much noise?

Stop that annoying "ticking" of Harley-Davidson rockers.

The Harley Twin Cam engine has a gap between the rocker arm shaft and the bolt that's supposed to lock it. This gap allows the shaft to rotate and hit the bolt, causing a metallic sound, which is often mistakenly attributed to...

Brake fluid is a fundamental component of the hydraulic braking system. It transmits the force exerted on the brake lever to the caliper pistons and also prevents the formation of water droplets in the circuit, thus preventing component corrosion.

How many types of brake fluid are there on the market? What is the DOT rating for brake fluids, and how do they differ from one another?

Harley-Davidson's electric bike project is called Serial 1 Cycle Company, the nickname of Harley-Davidson's oldest known motorcycle, built in 1903.

This announcement is accompanied by a new prototype...

Checking the charging system in 3 steps

On this occasion, we're going to conduct an eminently practical tutorial to check whether any motorcycle's charging system is working properly.

Before starting the tests, let's briefly define the components...

Get your bike ready to hit the road again

When our motorcycle has been idle for an extended period of time, it's advisable to perform a series of checks and tune-ups to once again enjoy the pleasure of riding in optimal conditions. Let's review the key points when checking that everything is OK...

Surely if you are the owner (or know someone) of a Twin Cam 96”, manufactured between 2007 and 2011, you are familiar with the typical starting problem of these models: the engine turns, but suddenly, you hear strange noises (as if something were about to break), and the pistons move back, causing smoke to come out of the air filter.

This setback is due...

Did you know the Indian FTR has hidden traction and engine management modes that can be unlocked?

S&S Cycles' latest addition to the FTR line is a technological device that allows the base model FTR1200 to enjoy the additional modes that...

The Sportster model will be discontinued in Europe and probably in the USA in the near future.

The main reason for the end of the Sportster is...

For an internal combustion engine to function, we need three elements: air, fuel, and spark. In a carburetor engine, fuel is drawn in by the vacuum generated inside the engine. In modern EFI engines, fuel is injected under pressure in the correct amount and at the precise moment into the combustion chamber.

Under pressure

The fuel pump is used on motorcycles with electronic fuel injection (also on some carburetors with remote fuel tanks) to...

A vehicle's clutch is the component that connects the engine to the transmission, allowing the force (torque) coming from the engine to be connected or disconnected to the transmission, in order to change gears, for example.

We've come across a motorcycle that revs up when we accelerate, but the vehicle's speed doesn't increase accordingly. Or, in extreme cases, we engage first gear and when we release the clutch lever, the motorcycle doesn't move forward. In both situations, we probably have...

When winter arrives and temperatures are very low, the routine of warming up the engine before hitting the road begins. Because the engine is so cold, it's tempting to let it idle until it warms up sufficiently.

But, letting a cold engine idle for a few minutes can damage it.

Do you want to know why?

During the break-in period, new components generate excessive friction and heat, so specific steps must be followed to ensure the mechanical elements "break in" properly, thereby prolonging their useful life.

Although there are many procedures for performing this break-in, most manufacturers and experts recommend two key points to keep in mind:

Just six months ago, BMW Motorrad revolutionized the world of customization with the world premiere of the Concept R 18 at the Concorso d'Eleganza Villa d'Este.

Now, at the EICMA international exhibition, it has successfully unveiled a...

In motorcycles older than 10 years, with metal fuel tanks, internal corrosion is common. This is caused by the chemical components of the fuel (especially if it contains large amounts of ethanol) and, above all, by the humidity that comes from the outside air and condenses in the tank.

The best way to permanently remove this corrosion is to...
