What does throttle by wire mean on a motorcycle?
The term ride by wire is analogous to 'drive by wire' which is used in case of four wheelers. In simple terms, it refers to the absence of mechanical linkage between accelerator and throttle. Instead, various sensors and actuators (connected by wires) control the fuel-air supply going to the engine.Nov 18, 2016
Is throttle by wire good?
Throttle-by-wire creates harmony between the throttle angle, ignition and fuel, which allows the engine to create more torque and power. Also, throttle-by-wire can better utilize variable valve timing.

Is drive-by-wire better?
The signals from the Throttle Position Sensor and the input from the potentiometer connected to the accelerator pedal, helps the ECU to perform the 'throttling' with greater accuracy. Drive-By-Wire eliminates the need for any mechanical linkages and hence aid in weight savings.Mar 1, 2018
How does a motorcycle throttle work?
The throttle controls how much air is allowed to flow through the carburetor, and the flow of air is what controls how much fuel is also fed into the engine. The Venturi Principle/Effect states that when air flows through a restriction of a tube (narrowing), the air speed increases, and air pressure decreases.Mar 20, 2020

What is the Throttle on a Motorcycle?
The majority of powersport vehicles are powered by internal combustion engines, and motorcycles are no exception.
What does the Throttle do on a Motorcycle?
What does the throttle do on a motorcycle? Contrary to popular belief, the throttle on a motorcycle doesn’t directly regulate the amount of gas entering the engine. Instead, what the motorcycle throttle does exactly is control how much air flows into the engine.
How does the Throttle Work on a Motorcycle?
The throttle on a motorcycle works in a very simple way. The twist throttle (right grip) is directly connected to the throttle valve with a cable. But on some of the newest motorcycles the throttle is controlled electronically. Twisting the throttle opens the valves, which allows more air to enter the engine.
How Do You Hold the Throttle on a Motorcycle?
Keeping safety in mind it’s recommended that you always hold the throttle on a motorcycle with all four fingers. The only time you have to move your fingers is when using the brake lever when you want to use the front brake. Best practice is to keep your wrist in a straight position, which results in a convenient and safe body position.
How do You Control the Throttle on a Motorcycle?
As a rule of thumb, you always have to control the throttle on a motorcycle by twisting your right wrist. One typical mistake of beginners is that they try to control the throttle by moving their whole right arm. Unfortunately, this leads to a disadvantageous riding position. Besides fatigue, it can even cause dangerous situations.
Which Way Do You Twist the Throttle on a Motorcycle?
Which way do you twist the throttle on a motorcycle? Don’t worry, as it’s pretty simple. If you twist the throttle backward the engine RPM increases, which causes the motorcycle to accelerate. In contrast, twisting the throttle forward reduces engine power which leads to deceleration.
What does Rolling the Throttle Mean?
Rolling the throttle means turning the throttle grip gently, which gradually feeds the engine with the gas/air mixture. This results in a slower, more moderate acceleration. At the other end of the spectrum there is an action called “hammering the throttle” or “twisting the throttle.” This means the throttle grip is quickly rotated backward.
Valve Overlap, Duration, and Lift
The long valve overlap usually found on “full race” cam grinds made this even worse. Overlap is the period around top center at the end of the exhaust stroke when the exhaust valves are still in their closing process, but the intakes have already begun to lift.
What the rider wants is not a certain amount of throttle opening, but rather a certain amount of torque
The traditional way past all this toil and trouble is to shorten the overall time that the valves are open (valve duration) and try to recover the loss by lifting the valves farther (increased valve lift).
The Throttle-by-Wire Solution
What does this have to do with throttle by wire? All the riders who have been through the above experiences have had the same thought: “Man, if I could just somehow learn to ride this thing, nobody would see which way I went!”
How does a bike computer work?
The bike's computer interperets your throttle input from your right wrist. That data, plus some other info from the bike it uses servos to operate the intake and meter's the fuel to give you your desired result. At least that's the way I understand it.
What is a fly by wire?
Fly by wire was the moniker given to a wire transmitting signals to a computer verses a cables connected to flaps and rudders. What this means to car and bike operators is that you're able to transmit more input to a computer by wire than you are just cables attached to a carb's butterflys. Telling a computer to keep the bike travelling ...
What is ride by wire?

In simple terms, it refers to the absence of mechanical linkage between accelerator and throttle. Instead, various sensors and actuators (connected by wires) control the fuel-air supply going to the engine.
When did Yamaha start using ride by wire?
Yamaha pioneered the use of ride by wire technology in 2006 on YZF-R6.
What are the advantages of ride by wire?
Firstly, it ensures precise control of the fuel air mixture going in the engine which enhances engine efficiency. This ultimately results in emission reduction. In addition, ride by wire technology allows setting up of various riding modes like cruise mode ...
Why is ride by wire important?
This is because emissions from an engine generally increase with capacity and power. To pass stringent emission norms without compromising on performance, ride by wire technology plays a key role.
Does a twist of the accelerator control the fuel mixture?
Thus, in such engines, a twist of the accelerator would directly control the supply of fuel-air mixture to the engine. However, this is not the case with ride by wire system as there is no cable connection between accelerator and throttle.
Why do carburetors have second throttle plates?
And just as it happened with carburetors, injection eventually morphed to include a second set of throttle plates—not unlike the vacuum slide in a CV carb—for the purpose of improving throttle response and enabling ever larger throttle bodies to permit horsepower increases.
Why use Ride by Wire?
Ride by wire changes everything, though, because the primary throttle plates (the only ones in an RBW system) provide the best engine response. They can be used in conjunction with fuel/ignition changes to carefully moderate power to the rear wheel. With RBW, TC is much more flexible, smoother, and effective.
What valve did carburetors use?
Very early carburetors used a simple butterfly valve to control airflow, and fuel delivery was passive. As air was drawn past various orifices, low pressure in the throat of the carb caused fuel to be drawn from the bowl, mixed with the air traveling past, and fed into the engine.
Does twisting the throttle squirt more gas into the engine?
Twisting the grip doesn’t squirt more gas into the engine —at least not directly. It simply admits a larger volume of air that then draws more fuel into the cylinder. Managing airflow is what the throttle is all about, and over the decades throttle technology has followed an interesting and cyclical path. Very early carburetors used ...
Does Yamaha have a mechanical linkage?
Yamaha has an additional mechanical linkage that can force the throttles closed in the event of an electronic failure ©Motorcyclist. When you give command of the throttle to an electronic device, you want to know that the bike won’t go all HAL 9000 on you. No need to worry; there are myriad safeguards in place.
Does riding by wire give you gas?
Let Ride-by-Wire Electronics Give You a Helping Hand. The term “give it some gas” is misleading. Twisting the grip doesn’t squirt more gas into the engine—at least not directly. It simply admits a larger volume of air that then draws more fuel into the cylinder.
Does RBW work on bike gears?
Also, for many years, bike manufacturers have used different fuel and ignition maps for each gear in an effort to tailor, usually by trimming back, power in the lower gears. No longer needed: RBW does this automatically, preventing, in essence, full power from ever reaching the rear wheel in the lower gears.
