\"Moto_pilotes_rollie_free\"<\/a> <\/p>\n

A mon entourage qui s’int\u00e9resse un peu aux deux-roues (ou qui fait mine), j’ai coutume de d\u00e9crire Jarno Saarinen<\/a> comme le Fosbury de la moto. Le premier \u00e0 avoir pos\u00e9 ses "demi-cannes" sur la piste m’a toujours fait penser \u00e0 l’athl\u00e8te am\u00e9ricain, quand ce dernier \u00e9crasa tous les concours de saut en hauteur gr\u00e2ce \u00e0 son passage de barre sur le dos, style de franchissement r\u00e9volutionnaire \u00e0 l’\u00e9poque. Je crois alors que Free peut \u00eatre compar\u00e9 \u00e0 Vuarnet, skieur auteur de "l’oeuf" \u00e9ponyme. <\/p>\n

\"Ski_jean_vuarnet_et_sa_position_de_\"<\/a> L’oeuf de Vuarnet est cette position tr\u00e8s ramass\u00e9e, invent\u00e9e par Jean V., ici en photo, qu’adoptent tous les skieurs de descente et aussi de KL (kilom\u00e8tre lanc\u00e9) avec des variantes, car elle offre le meilleur Cx, coefficient de tra\u00een\u00e9e.<\/p>\n

Et c’est cette recherche de la meilleure p\u00e9n\u00e9tration dans l’air qui conduisit Free \u00e0 la photo ci-dessus. <\/p>\n

L’histoire dit que, initialement, ce revendeur d’Indian (la marque am\u00e9ricaine c\u00e9l\u00e8bre pour ses cruisers aux garde-boues jupes, une entreprise en pleine renaissance \u00e0 l’heure actuelle) portait son ensemble en cuir qui l’emp\u00eachait d’aller au del\u00e0 d’un d\u00e9j\u00e0 fort honorable 147 mph (miles per hour), soit 236,6 de nos kilom\u00e8tres\/heure.<\/p>\n

Il prit l’initiative (g\u00e9niale) et le risque (certain en cas de chute, mais calcul\u00e9) de s’en d\u00e9barrasser, et de ne se v\u00eatir que d’un bonnet de bain, d’un maillot, de bain \u00e9galement, ainsi que d’une paire de tennis. Ce qui lui permit d’atteindre les 150,313 mph ou 241,9 km\/h, sur le c\u00e9l\u00e9brissime lac sal\u00e9 de Bonneville dans l’Utah. <\/p>\n

Soit le "Go your own way", slogan de Triumph conjugu\u00e9 au "Think different" d’Apple (oui, j’ai os\u00e9). Rollie Free \u00e9tablissait un nouveau record du monde de vitesse, c’\u00e9tait il y a bient\u00f4t soixante ans, et c’\u00e9tait sur une Vincent<\/a> HRD Black Lightning.<\/p>\n
