Similar to how Alpinestars released the telemetry from Marc Marquez’s 209 mph crash at Mugello, the Italian motorcycle apparel company has downloaded the 0′s and 1′s from Jorge Lorenzo’s Air-Tech race suit, to show us the physics involved from his collarbone-breaking crash.
Marc Marquez would almost certainly like to forget this past weekend at Mugello for the Italian GP. Heads up to the spoiler alert, but not only did he make an unforced error during the race, crashing out of second place all by his lonesome (with a comfortable margin fore and aft, we might add), but the young Spanish rider also had one of the fastest crashes ever in the MotoGP Championship during Friday’s Free Practice 2 session.
Losing control of his Repsol Honda RC213V at 209.9 mph as he approached the San Donato corner during the race, Marquez had to jump away from his race bike, at roughly 170 mph, in order to avoid the rapidly approaching wall barrier. Escaping with a battered chin, a small fissure to his humerus bone, as well as minor soft-tissue injuries to his shoulder, Marquez came out of the incident in FP2 rather well, all things considered.
Now that Marquez has gotten a clean bill of health from doctors in Barcelona (he will have to undergo some physio the next few days though), Repsol and others in the paddock can breathe a sigh of relief, and begin to analyze the crash in more detail. Helping add insight to the crash, Alpinestars has released the telemetry from Marquez’s Tech Air race suit, which shows the g-forces involved during the crash, as well as the deployment time of the suit’s airbag.
Here at Asphalt & Rubber, we spend some pixels talking about the finer points of helmet usage, especially when it comes to the debate regarding mandatory helmet laws. Looking at helmets from 50 years ago, and the basic concept hasn’t changed all that much in the time since.
A hard shell, some impact material, and a soft lining mated to a visor and chin-strap system, over the last half-century most of the improvements to the basic helmet design have been for added fit and comfort, or cheaper and lighter materials — even the more creative and innovative designs that are being hocked around the internet right now don’t stray far from the current concept.
Think 50 years ahead though, and it is hard to imagine the same shapes and designs staying constant. In fact, it becomes even possible to imagine motorcyclists wearing not helmets at all. No, I am not talking about some sort of libertarian movement that will rush through our political system, freeing us from the shackles of big government. Instead, I am talking about the true next-generation of safety devices for the gray matter that resides between your ears, which might put the mandatory helmet law debate to rest (well…probably not).
Getting a look at Dainese & AGV’s 2012 collection, Asphalt & Rubber was down in Orange County earlier this week to see the highly anticipated Dainese D-Air Racing leather suit, which has a four liter airbag system that helps reduce the risk of injury during a motorcycle crash. Dainese has been working on the D-Air Racing system for 10 years now, and after soft-launching the airbag suit in Europe, the Italian company is ready to bring the game-changing technology to American soil.
If you watch MotoGP or World Superbike, you have likely already seen the roughly one pound (650 grams) D-Air Racing suit at work, as riders like Valentino Rossi, Nicky Hayden, Stefan Bradl, Leon Haslam, and Max Biaggi have been wearing Dainese’s airbag leathers while racing, and have also been providing the company with feedback on the D-Air’s design and development. In addition to deploying an airbag that protects a rider’s neck, chest, and shoulders, the Dainese D-Air system also provides a telemetry package that track riders can use in lieu of a basic motorcycle data acquisition system.
Igor Chack may only be 26 years old, but this designer’s eyes have a taste for something old with a modern twist. Taking his inspiration from the 1929 Soviet Izh–1, Chack sees this iconic motorcycle coming to life nearly 80 years later with a hybrid powertrain and a bevy of features not only unthinkable in 1929, but not seen on today’s motorcycles as well.
Chack’s design centers around a 850cc hybrid motor that makes 140hp when running off of fossil fuel. 50% of the motor is made from heat resistant reinforced plastic, which helps reduce weight and enclose the integrated electric circuits. On the electric side of the powertrain there is a 60kW brush-less motor that’s built into the rear rim, along with its own two-speed gearbox. Chack estimates the combo could achieve 80mpg with the bike’s on-board fuel management system deciding which drive to use.
Motorcycle safety technology has clearly entered a new phase of development with airbag systems being pursued by a variety of apparel manufacturers. The latest company to enhance it’s riding suits with the technology is Alpinestars, purveyor of fine jackets, gloves, boots, etc. Alpinestars’ airbag system, dubbed the Tech Air Race, the system easily integrates into what the company calls the Electronic Airbag Protection Suit. The two components combined create a leather racing suit that can calculate in eight milliseconds whether a rider is crashing, and if so, deploy a pair of airbags that protects the rider’s body.
