2007 Yamaha YZF-R1

Since I wrote Part One of this impression on Saturday, I've had a few days to arrange my thoughts. After this period of contemplation, I feel I'm ready to put pen to paper (or, more accurately, fingers to keyboard) and share a more in-depth description of my riding experience last week at Laguna Seca.


2007 yamaha R1

A good starting point would be the motor, as this is where the 2007 R1 has received the most drastic changes, and where yamaha's engineers have made the greatest improvements over the previous model.

The 2005-2006 R1 was often criticized for having a powerband biased too heavily toward the top-end; the bike was a rocketship when the rider kept the needle in the upper quarter of the tachometer, but in the lower RPM range, it was out-powered by rivals like the suzuki GSX-R1000 and kawasaki ZX-10R. This "600-like" powerband was great on the racetrack, but in everyday street riding, the (relative) lack of low-end grunt and mid-range pull was disappointing.

As I discussed in Part One, the R1 design team was tasked with the seemingly contradictory goals of eliminating or mitigating these shortcomings, while at the same time significantly reducing the new bike's emissions. To accomplish this, they decided to give up yamaha's traditional five-valve cylinder head design in favor of a more conventional four-valve layout, which allowed for a smaller combustion chamber and thus a higher compression ratio (now 12.7:1). The four throttle bodies feeding air to the new cylinder head are topped with an innovative system, called 'YCC-I', which varies the length of the intake runners depending on RPM and throttle position. Below 10,400rpm, the intake runners are 140mm in length, which significantly boosts low-end and mid-range power output. When the R1 spins past 10,400rpm (assuming the rider is applying at least 57.5% throttle), the upper section of the intake runners is lifted away, leaving the air to enter through the 65mm lower sections - a length optimized for high-rpm power output.

The throttle bodies also feature the same 'YCC-T' (yamaha Chip Controlled Throttle) throttle by wire system that first debuted on the 2006 R6. Although the throttle is still connected to two cables which run down to the throttle bodies, these cables do not directly actuate the throttle body butterflies. Instead, the rider's wrist motion is translated by a throttle position sensor, which tells the ECU how hard he wants to accelerate. The ECU then makes the decision as to how far and how quickly to open the butterflies, maintaining maximum air velocity in the intake tract to maintain maximum acceleration (consistent with the demands of the rider, that is). Why not locate the throttle position sensor directly on the twist throttle and eliminate the cables, you ask? Well, besides actuating the throttle position sensor, the return cable actuates a small arm that manually closes the throttle body butterflies. Thus, in the unlikely event of an electronic malfunction that left the butterflies open (the throttle-by-wire equivalent of a stuck throttle), the rider can manually close the butterflies by merely closing the throttle.

• 2005 Yamaha R6 (YZF-R6)

We started out to give the 2005 R6 more horsepower and a new fork, and wound up engineering a nearly new motorcycle.

Staying out front in the Supersport wars takes power:

New camshafts
Bigger throttle bodies
Improved fuel injection
Revised intake funnels

... and more, result in a smoother, fatter powerband with three more horsepower at 13,000 rpm.
To channel that power, a new, fully-adjustable inverted fork with 41mm tubes was added for the most precise handling possible.

It was too good a place to resist mounting powerful new 310mm front disc brakes, radial calipers and a radial master cylinder to even further exploit the R6’s amazing front-end feel.

The added rigidity of the new fork led to a redesign of the main frame to accommodate new rear suspension linkage.

Light weight, razor-sharp handling, unsurpassed overall balance – elevated to the next level.
That's why the R6 was the winner of Motorcycle-USA.com's Supersport Shootout for 2003 and 2004.

Anybody up for a track day?

With back to back Canadian Pro 600 Sport Bike championships to its credit, the 2005 Yamaha R6 is poised for even greater success with a host of important improvements for the 2005 model year. At first glance, the outward appearance of the new R6 may look similar, but looks are deceiving. The improvements have a dramatic effect on engine performance, braking power, handling and stability. The sharp handling and brilliant responsiveness of the R6 have been further enhanced by an all new 41mm inverted front fork and new 70 series front tire, while larger radially mounted brakes will have a significant effect on stopping power. New 40mm throttle bodies and revised fuel injection mapping and ECU settings have increased engine output by 3 horsepower. The upgrades are extremely significant and will become very obvious when the bike is ridden.

Yamaha Canada is pleased to announce that the new 2005 - R6 will come standard with an immobilizer ignition system that significantly reduces the possibility of theft. Yamaha Canada is proud to take the lead role in addressing our customers concerns regarding insurance rates and availability.

Features & Benefits

New for 2005

Engine upgrades in the form of 40mm throttle bodies, revised fuel injection and ignition mapping, new camshafts and intake funnels, etc., all result in a 3-horsepower increase at the same rpm as before with more power across the board.

New, fully adjustable inverted fork with 41mm tubes further reinforces R6’s main strength: precise handling. New, cast top triple clamp and forged lower clamp also increase rigidity, and work with revised handlebar positioning.

To complement the new fork, the rear section of the Deltabox III main frame was revised internally to work with revised swingarm linkage and mounts for improved handling.

Lighter, 310mm front brake discs replace 298mm units. New radial-mount four-piston calipers and radial master cylinder provide greater braking power and feel.

120/70-ZR17 front tire replaces previous 120/60-ZR17 for improved handling.

Twin, ring-type radiator fans are now used to ensure optimal engine cooling.

Revised headlight lens and revised under-cowl for even better style.

Chassis/Suspension:

· Radical, lightweight aluminum Deltabox IlI frame offers the perfect rigidity balance. The result is incredible handling response. The engine is a fully stressed chassis member allowing for a super-light frame design.
· Chassis geometry has been revised for 2005 including; wheelbase (1380 to 1385mm), caster angle (24 to 24.5 degrees) and trail (86 to 95mm) have been changed for 2005.
· Yamaha's exclusive Controlled Filling Die Casting (CF casting) is used to produce an incredibly sleek new swingarm that is remarkably strong and light by pinpointing exactly where material needs to be. Pivot position and swingarm length (576mm) are optimized for even greater traction.
· Removable aluminum rear subframe uses CF casting technology to provide lighter weight and fewer welds as well.
· All new, fully adjustable 41mm Kayaba inverted front fork offers 120mm (4.7'') of wheel travel. The new inverted forks offer incredible suspension performance with ultra-precise feedback. Adjustments include; 8 positions of spring preload, 13-way compression damping and 10-way rebound damping. The inverted design not only reduces unsprung weight but also increases the rigidity of the fork assembly.
· Revised fully adjustable Monocross link rear suspension utilizes a piggyback-style shock providing 120mm (4.7'') of wheel travel. The shock settings have been revised to maintain the ''suspension balance'' with the new inverted fork. Adjustments include: 8 positions of spring preload, 20-way compression damping and 16-way rebound damping.
· The relay arms of the rear link-type suspension have been modified to match the new fork and to enhance suspension performance. The seat height of the new 2005 R6 has been increased by 10mm (0.4'') due to the changes in the suspension.
· All new radial mount, 4-piston calipers squeeze new larger 310mm dual front disc brakes. The new mounting system helps to reduce caliper distortion for improved braking performance with excellent control and lever feedback. The larger 310mm discs are 4.5mm thick thereby reducing overall disc weight by 7%.

The Tomahawk is a Viper V-10 based motorcycle, a 500 horsepower engine with four wheels beneath it.
Chrysler will be selling the original Tomahawk concept and nine replicas through Neiman Marcus, for up to $555,000 each. The motorcycles cannot be licensed, so they cannot be legally driven on public roads. A Chrysler spokesman told Reuters they were meant as rolling sculptures.

Rumors had the Tomahawk selling for under $200,000, most likely at a loss or breakeven price, for publicity purposes - but still fully drivable. Wolfgang Bernhard, Chrysler's not particularly respected first mate, was said to be enthusiastic about that project, so much so that hundreds were projected to be built at under $200,000 each. They reportedly cost Chrysler over $100,000 to build (admittedly the work is outsourced).

The Dodge Tomahawk can reach 60 miles an hour in about 2.5 seconds, and has a theoretical top speed of nearly 400 mph. Each pair of wheels is separated by a few inches and each wheel has an independent suspension. Bernhard said four wheels were necessary to handle the power from the engine.

The Tomahawk remains on display at auto shows - though well out of reach of the general public, elevated on a special display.

World's Most Dangerous Animals

Mosquito-over 2 million deaths per year resulting from malaria infection caused by mosquito bites.The mosquito is a member of the family Culicidae; these insects have a pair of scaled wings, a pair of halteres, a slender body, and long legs. The females of most mosquito species suck blood from other animals. Size varies but is rarely greater than 15 mm . Mosquitoes weigh only about 2 to 2.5 mg . A single flight can last about 4 to 5 minutes. They can fly at about 1.5 to 2.5 km/h and most species are nocturnal. Mosquitoes are believed to have evolved around 170 million years ago during the Jurassic era with the earliest known fossils from the Cretaceous era .(IMG:http://63.229.12.241/topicimages/s/sn/snake.gif) Snake-Over 100,000 deaths per year. Snakes , also known as ophidians, are cold-blooded legless reptiles closely related to lizards, which share the order Squamata. There are also several species of legless lizard which superficially resemble snakes, but are not otherwise related to them. A love of snakes is called ophiophilia, a fear of snakes is called ophidiophobia. A specialist in snakes is an ophiologist. An old synonym for snake is serpent ; in modern usage this usually refers to a mythic or symbolic snake, and information about such creatures can be found under serpent .(IMG:http://63.229.12.241/topicimages/s/sc/scorpion.gif) Scorpion-up to 5,000 deaths per year.A scorpion is an invertebrate animal with eight legs, belonging to the order Scorpiones in the class Arachnida.(IMG:http://63.229.12.241/images/n/ni/nilecrocodile.jpg) Crocodile-up to 2,000 deaths per year.A crocodile is any species belonging to the family Crocodylidae . The term can also be used more loosely to include all members of the order Crocodilia: i.e. the true crocodiles, the alligators and caimans and the gharials.(IMG:http://63.229.12.241/images/e/el/elephantreaching.jpg) Elephant-over 600 deaths per year. Elephantidae is a family of pachyderm, and the only remaining family in the order Proboscidea in the class Mammalia. Elephantidae has three living species: the African Bush Elephant and the African Forest Elephant and the Asian Elephant . Other species have become extinct since the last ice age, which ended about 10,000 years ago. Elephants are mammals, and the largest land animals alive today. The elephant's gestation period is 22 months, the longest of any land animal.
