F1 2008 and the Science of F1 Motorsport

As we enter another season of Formula One racing, many fans hopes rest on Lewis Hamilton, Fernando Alonso, Kimi Raikkonen and other F1 superstars; but lets not forget that it takes a lot more than just a good driver to win a F1 race.

In order to be successful in the highly competitive world of F1 motorsport, every technical advantage helps - no matter how small. Firstly, if you take a look at an F1 car, youll find a huge amount of technology under - and over - the bonnet, and everything from the gears to the gas pedal has been meticulously designed and refined to create a lighter, smoother, faster car. Meanwhile, ongoing testing of the cars aerodynamic properties continues to create faster vehicles that stick to the road, and every single surface of a modern F1 car, from the tyres to the drivers helmet, has its aerodynamic qualities considered and researched.

At the centre of F1 is the safety of the drivers, the pit teams and the fans. The heart of each car is built with an extremely strong structure nicknamed "the tub". This is the drivers cockpit and survival cell, and is constructed mainly from carbon fibre. The fact that so many drivers have walked away (or at least been helped out of) some seemingly catastrophic accidents is testament to the highly successful protective construction on the survival cell. The cars are also designed so that drivers can get out of the cockpits in the least possible time to avoid burns. The current regulations state that all drivers should be able to get out in no more than five seconds without having to remove anything except the steering wheel.

Many might be surprised to hear that F1 drivers are some of the most highly conditioned athletes on earth. You might think that little physical prowess would be needed for a sport that involves sitting in a car; but on the contrary, a huge amount of stamina and endurance is required, with drivers having to endure high G-force cornering which can cause extreme stress to their bodies. Due to the hot climates that many of the F1 races take place in, such as Australia, Singapore and China, the drivers must be able to handle high temperatures for long periods, and they can lose as much as 3 litres of sweat during a race!

And lets not forget the other members of the team that are so vital to success in this fast paced motorsport. Drivers may get most of the attention, but F1 is a team sport, and the speed and precision at which a teams pit-crew can refuel and change a tyre or make more serious repairs will have a significant impact on the drivers lap time and position in the race; a well oiled pit-crew can perform their tasks in just seconds.

So without taking anything away from the drivers of F1, we can see that it really is a team sport, and without all the research, technology and hard work from their team mates, those wining drivers wouldnt be able to spray each other with champagne on the podium.

This is the Fastest Electric Motorcycle

Motorcycle racing team from Italy, CRP Racing, recently introduced electric motorcycle racing, eCRP 1.4. This motor is designed to replace eCRP 1.2 has won racing electric motor 2010.

Introduction of environmentally friendly motor racing is once again declare ourselves to go down in the arena of e-Power FIM & riders Alessandro TTXGP with Branetti.

eCRP 1.4 uses lithium-polymer with a weight of 7.4 kilowatt hours of 52 kilograms. This motor can achieve a maximum speed of 220 kilometers per hour. "This bike has a top speed of electric motors,"wrote the TG Daily.

This motor can accelerate from 0-100 km / h in just 3.2 seconds. eCRP 1.4 also features a datalogger and sensors for GPS, dashboard racing, the latest Dual DC motor and an integrated air cooling.

The motorcycle is also equipped with a datalogger system that can record sensor for front and rear suspension, throttle, entry-exit control voltage, and monitors the condition of the engine temperature. All will be integrated with GPS.

These motorcycles can be rented for racing. Rental fee from U.S. $ 7,200, or about Rp65 million per three-day race. (eh)

The New Hand Controls Part IV The Ending

All the new stuff. You can even see the new hi/lo beam switch
on the headlamp bucket if you look closely.

The black paint is now as sanded off as I care to make it,
and the levers are new silver units (that got Scotchbrited)


The new hand controls are officially done - for now. The final details are as follows:

1. A non-dimpled Biltwell Generation II Frisco bar in chrome was trimmed of 3/4" from both ends and buffed with Scotchbrite.
2. The internally wired POSH Factory switches in brass were mounted to the left and right controls, controlling both the L/R signal and horn on the left, and the Run/Kill switch with a start button on the right.
3. A pressure activated banjo bolt brake light switch was installed on the front master cylinder, thus preserving front brake activation of the brake lights.
4. The headlight hi/lo beam switch was rerouted from the handlebars to the headlamp bucket. The new switch is now a hi-off-lo beam switch.
5. The Biltwell Whiskey Throttle in silver was set up to run a single cable setup and Biltwell Kung Fu grips were stuck on with the fiancees John Freida Collection hairspray.
6. The original lever assemblies were reused but modified with an angle grinder to eliminate the lip and extra tabs that secure the levers to the stock housings. The remaining black paint was removed with a wire brush, a 120 grit flap wheel and by hand with emery cloth.
7. Finally, the stock black clutch and front brake levers were replaced with silver ones which also ended up getting Scotchbrited.

No major problems were encountered during the installation and everything went pretty smoothly, although it was a little more time consuming than I originally anticipated.

The 2013 MV Agusta Rivale 800 Preview


MV Agusta released all the info ahead of the bikes official unveiling at the EICMA in Milan. Thie name is the Rivale 800. This bike builds on MVA’s line of inline three motorcycles, joining the F3 675, the Bruatle 675 and the all-new Brutale 800. These bikes are all younger siblings of MV’s F4 and the new Brutale 1090. Its takes a clear aim at one competitor – the Ducati Hypermotard. The styling attributes of the Rivale 800 display this; the front appears like Ducati’s Hypermotorad. But what’s also interesting is the rear tail section – it takes styling from Ducati’s Diavel. 


Same as Brutale 800, the Rivale features the signature steel-trellis frame and single-sided swingarm, all united through two aluminum-alloy plates. MV Agusta says the angle of the steering head on the Rivale 800 is half of a degree more open than the Brutale 800. The excursion of the fork and shock have also been increased to provide more comfort and conformity to the road surface.

The new 800′s engine is basically a bored-out version of the 675. The 800 pushes 125 horsepower at 11,600 rpm, which is 12 ponies more than the 675, and 60 ft. lbs. of torque at 8600 rpm. The engine features the counter-rotating crankshaft, something once only used in MotoGP. The design reduces inertia while changing direction, helping the bike’s overall balance.

For comfortable ridding, the Rivale 800 uses Marzocchi and Sachs components of suspension, which feature adjustable spring preload, hydraulic compression and rebound damping. And for stopping the Rivale 800 are dual, 320mm discs up front from squeezed by Brembo four-piston radial calipers, and a single 220mm disc out back squeezed by a twin-piston Brembo caliper.

The Rivale 800 also features a new dash. The compact "monochrome" fully-digital, mult-function dashboard was optimized for not only looks within the front fairing. MV Agusta says the Rivale 800 should be available in the second half of 2013, and retails for around $13,970 (10,990€).
