Motogp Technology

Aimed at the enthusiast who would like to gain a greater understanding of technical and design issues facing MotoGP constructors, this fascinating book provides detailed analysis of the cutting-edge technology used in the sport’s premier class today. Each area of a racing motorcycle’s design is explained and separate chapters for each manufacturer trace the development of each machine over the years through to the detailed specification of the current version.

The World Championship Grand Prix (WCGP) is the premier championship event of motorcycle road racing. The WCGP was established in 1949 by the sport's governing body, the Fédération Internationale de Motocyclisme (FIM), and is the oldest world championship event in the motorsports arena. This book, developed especially for racing enthusiasts by motorsports engineering expert Dr. Alberto Boretti, provides a broad view of WCGP motorcycle racing and vehicles, but is primarily focused on the design of four-stroke engines for the MotoGP class. The book opens with general background on MotoGP governing bodies and a history of the event’s classes since the competition began in 1949. It then presents some of the key engines that have been developed and used for the competition through the years. Technologies that are used in today’s MotoGP engines are discussed. A sidebar discussion on calculating brake, indicated, and friction performance parameters provides mathematical information for readers who like such technical details. Future developments of MotoGP engines, including the use of biofuels and recovery of thermal and braking energy, are presented. The introduction concludes with a chart that details the winners of the various classes of WCGP motorcycle racing since the competition began in 1949. The bulk of the book consists of four previously published SAE technical papers that were expressly chosen by Dr. Boretti to provide greater insight to the relationships between engine parameters and performance, namely the influence on friction and mean effective pressure of traditional spark ignited four stroke engines tuned for a narrow high power output. The first paper provides the reader with a quick way to estimate the friction loss and engine output. The second paper discusses output and fuel consumption of multi-valve motorcycle engines. The third paper, published in 2002, compares WCGP engines developed to comply with the then-new FIM regulations that allowed four-stroke engines in the competition. The fourth paper examines specific power densities and therefore the level of sophistication and costs of MotoGP 800 cm3 engines. This paper shows the performance of these as well as the 1000cc SuperBike engines. The fifth paper presents four engine concepts including one for a MotoGP/Superbike with 2 and 3 cylinders. The sixth paper compares 3 and 4 in-line, V4, V5, and V6 layouts through 1-D engine simulations. The seventh paper considers the actual operation of 800cc MotoGP engines on the race track, where the percentage of the duration in fully open throttle is less than 20% of the race, but the partial throttle is used for as much as 80% of the race. The final paper in the compendium reports on the Honda oval piston engine concept.

This book brings together research working at the boundary between design knowledges and mobilities, offering a novel collection for both theorists and practitioners. Drawing upon detailed case studies, it demonstrates the diverse roles of design in shaping mobility at different spaces and scales: across cities; within different types of buildings and infrastructures; and through commuting, work and leisure activities. A range of international scholars illustrate the designed mobilities of car parks, traffic lights, street benches, pedestrian wayfinding systems and accessible design in the urban environment; they examine spaces within hospitals, airports and train stations and investigate design practices for bicycles, future urban vehicles and MotoGP motorcycle racing. Other contributions explore overlooked mobile artefacts such as television and video game remote controls, 3D printing and the types of packaging which enable objects themselves to move around. This book demonstrates how the tools, assumptions and processes of design shape spaces of mobility, and also illuminates how shifts in the fluidity and circulation of people, practices and materials in turn reconfigure practices of design. Mobilising Design develops multi-disciplinary understandings of design, drawing upon diverse literatures including design history, product design, architecture and cultural geography. By highlighting often invisible artefacts and associated knowledges and controversies, the book foregrounds the taken-for-granted ways in which everyday mobility is designed. It will be of interest to scholars in geography, sociology, economic history, architecture, design and urban theory.

Set your pulse racing with this stunning visual guide to over 1000 pin-up machines - iconic symbols of wanderlust, speed, and the open road. From Gottlieb Daimler's gas-powered "engine on a bicycle" which set fire to the seat on its first outing, to superbikes such as the Ducati 916, Motorcycle: The Definitive Visual History takes you on an enthralling tour of the bike's history. It shows you bikes that appeal to the head - practical forms of transport - and to the heart - a parade of classic pin-ups including cult machines such as the Honda RC30, the Triumph Bonneville, and the Harley-Davidson XR750. Motorcycle: The Definitive Visual History shows the brilliance and impracticality of different designs and features detailed cross-sections of engines such as the air-cooled two-stroke. It explains how the great marques such as the Royal Enfield, the "legendary" Indian Scout, Vespa, and Norton all became household names. Whether you are a hardcore enthusiast or looking forward to your first machine, this is one title you cannot be without.

Injury. Adrenaline. Addiction. These are the things that fuelled one man's race to international stardom as he pushed boundaries and took life on and off the bike to the limits. Starting out as a talented youth riding the desert tracks of California, his reckless nature and incredible talent earned him a position in the rarefied world of professional motorcycle racing. Despite the success in his professional life, his personal life was crumbling around him - John was battling with depression and temptation, which began to threaten his career, health and marriage, ultimately bringing him to a life of alcoholism, addiction and even smuggling. In his remarkable memoir, one of the world's most renowned riders takes us on a raw and unique journey to the extremes of fast living. John 'Hopper' Hopkins is an icon for motorsport fans worldwide. He won't let anything hold him back. He has broken almost every bone in his body (twice), suffered a bleed on the brain, and had a finger amputated... yet he continued to race. Finally, at the age of 35 - with his latest crash at Brands Hatch in 2017 putting him in rehab for two years - he decided to hang up his helmet. Leathered tells the incredible story of an unparalleled career. From bone-crunching injuries and alcohol-fuelled antics to the breakdown of his marriage, it unveils the true stories behind the lurid headlines.
