Motorcycle
sport is a broad field that encompasses all
sporting aspects of motorcycling. The disciplines are
not all "races" or timed-speed events, as
several disciplines test a competitor's various riding
skills Motorcycles vary greatly in design for each discipline.
Broadly speaking, motorcycle sport can be divided into
two categories: tarmac-based road disciplines and off
road. Within each of these disciplines, there are usually
sub-groups. These may include classic machinery , non-current
to various extents, miniature machinery. Grand Prix
motorcycle racing refers to the premier category of
motorcycle grand prix currently divided into three distinct
classes: 125 cc, 250 cc and MotoGP. Grand prix motorcycles
are purpose-built racing machines that are neither available
for general purchase nor can be legitimately ridden
on public roads; this contrasts with the various production
categories of racing, such as the Superbike World Championship,
that feature modified versions of road-going motorcycles
available to the public. |
