Converting a bike's kinetic energy from straight ahead to turning requires a negotiationwith physics in a couple of ways. First, a rider pushes the handlebars slightly awayfrom the direction of the turn.
Because the wheels act as gyroscopes, this countersteeringleans the bike in the opposite direction into the turn , which puts the tires at an angle,narrowing what engineers call the contact patch and making the bike easier to turn.
At the same time, the rider moves off the bike in the direction of the turn. Thelean angle of the motorcycle shifts the center of gravity to the side, causing the biketo turn, while the weight redistribution lets the machine stay slightly more upright.
At the point of maximum lean required to get through a turn at the highest possiblespeed, centrifugal force wants to pull the bike machine off the track, and the rideruses traction, gravity, and momentum to stay in the game. To explain why the machine moves at all, Falco invokes Newton's second law of motion:A force applied to an object will cause it to accelerate. On some tracks, grand prix motorcycles approaching tight turns must slow frommore than mph to around 40 mph. Friction on the brakes primarily the frontbrakes makes this possible.
Some of this heat is transferred to the hydraulic-brake fluid, which cancause brakes to lose stopping power, with potentially disastrous consequences. Engineers use space age ceramic materials to avoid this problem, and riders becomeskilled at getting on and off the brakes quickly. Successful race riding is a lot like paying taxes: You want to push the rules as faras you can without breaking them.
There is a very fine line between optimum corneringand crashing, where outward, downward, and forward forces balance precisely. But rules are rules. By Bruno dePrato October 28, Saying Goodbye to Wes Cooley. By Kevin Cameron. Yvon Duhamel Dies at Ask Kevin. Idle Thoughts On Carbs. Some say the first motorcycle race was flagged off the moment a second motorcycle rolled down the assembly line and riders have been battling hammer and tongs ever since that seminal moment.
Whether that account is actually true is irrelevant because motorcycle racing is ever evolving, with new models and rules changes spawning disciplines spanning the past century as specific and unique as the very machines homologated for use in domestic and international competition.
Motorcycle Racing News. By Staff. By Maria Guidotti. Misano: Weather, Tires, and a World Champion. Max Biaggi on Rossi, Racing, and Retirement. In this article, let's explore some of the most common questions about motorcycle racing. The first motorcycle race occurred as early as the s, with the British TT Isle of Man originating in and official regulation starting in This race occurred in and was the inception of a long tradition of motorcycle racing.
Around , banked wooden tracks were being constructed to serve as venues for the sport. The first world championships were held in The American Motorcycle Association was created in , which has grown exponentially from the original 93 to over , members. There are a variety of motorcycle racing types, each with different classes or divisions based on the power of the bike. Precision tuned sportbikes are typically used for these events.
Motorcycle racing on an ice track is truly stunning; The bikes' tires must be fitted with spikes or studs that allow them to grip the slippery terrain. Supermoto involves completing a course with differing types of terrain, including motocross-type terrain with jumps, flat dirt tracks, and the typical paved road or speedway. Riders use a bike that is a balanced hybrid of sport bike and dirt bike to be able to complete the race efficiently.
This type of race is incredibly skill-based and not necessarily dependent on the rider's speed as they conquer varied terrain. Riders complete a motorcycle drag race much like any typical top fuel quarter-mile race. MotoGP classes go all the way up to cc engines with amazing rev limits around 17, rpm, producing in excess of hp , which is more than enough when you're rocketing around the tarmac on a bike that weighs merely lbs dry. The average bore-stroke of the engine is 5. These usually have EFI electronic fuel injection and as standard run on octane leaded fuel.
