<原创+译文 >flat tracker 与 复古场地赛

    看够了晃得眼疼的chopper,一身痞子范儿的bobber，还有抬头撅腚骑姿的cafe racer，你还有另一种复古的选择：flat tracker宽阔但不高昂的车把，通过性高但坐姿平易近人，配上比街车轮胎抓地力更强的龟背胎，勾勒出flat tracker的常见形象。

因为喜欢，所以从一些国外网站找了些图片和文章，加之才疏学浅，只敢与各位同好交流探讨，难免有纰漏之处，感谢高人指正。

我们喜欢的是车，但是复古车必定有它自己的文化，不然也不可能流传至今而深受喜爱，同样的，要了解flat tracker，也要了解它的历史，这就要谈谈场地赛了（也有叫做绕圈赛的），为啥叫复古场地赛呢，因为之前的规则和现在差异很大，虽然现在还有类似的比赛，但已经是变种，甚至变种的变种了。

场地赛（绕圈赛）是一种围绕着卵圆型场地的摩托车竞速赛，比赛成员可以是个人或者团队，它因比赛场地的表面不同有不同的变种形式。（以后慢慢讨论和补充）最常见的比赛形式是speedway。在国际摩托车联盟（FIM）的管理下，这项运动在1920年代变得流行起来，并且一直持续至今。
(Track racing is a form of motorcycle racing where teams or individuals race opponents around an oval track. There are differing variants, with each variant racing on a different surface type.The most common variant is Speedway which has many professional domestic and international competitions in a number of countries.Administered internationally by the Fédération Internationale de Motocyclisme (FIM), the sport became popular in the 1920s and remains so today.)



绕圈赛通常是由4名、6名或者8名选手参与，选手们绕着逆时针方向，骑行4周、6周或者8周，除了最后一名外，其他选手均有积分。最终按照积分多少定输赢。

参赛的摩托车均为改装摩托，这些车辆没有刹车系统，燃料是甲醇（不是汽油），speedway比赛甚至使用连变速箱和后悬挂都没有的车辆比赛。使用甲醇作为燃料，原因是引擎可以达到更高的压缩比，这样赛车可以达到更高的速度，弯道时可达80英里/小时，尽管如此，过弯的速度主要还是依赖于骑手的总体技术水平。也正是因为如此，powersliding 或者 broadsiding这两种技术才被广泛的应用于各种形式的场地绕圈赛。

（Nature of the sport
Track racing involves between 4 and 6 sometimes 8 competitors riding around an oval track in a counter-clockwise direction over a set amount of laps - usually 4 to 6 sometimes 8 - with points being awarded to all but the last finisher on a sliding scale.
These points are accumulated over a number of heats, with the winner being the team or individual who has scored the most overall.

The machines used are customised motorcycles, these have no brakes and are fuelled with methanol. Speedway also uses motorcycles with no gears or rear suspension. The use of methanol provides an increased compression ratio to the engine resulting in higher speeds (approx 80mph when cornering) although the skill of Track Racing lies in the overall ability of the rider to control his motorcycle when cornering and thus avoid losing places through deceleration.This has resulted in powersliding or broadsiding being used as a technique in most variants of the sport to progress around the track.）

留待以后慢慢更新




（Track characteristics

Competitions take place on tracks which are defined by the FIM as being of the following:[1]

    Speedway - a track with a top surface in granite, shale, brick granules or similar unbound material rolled in on the base ground
    Long track - sand, shale or similar unbound material rolled in on the base ground
    Grass track - firm, level turf with minor undulations
    Ice Racing - ice with a minimum thickness of 10 cm

Variants of the sport
Speedway
Main article: Motorcycle speedway
A typical Speedway motorcycle

Speedway racing takes place on a flat oval track usually consisting of dirt or loosely packed shale, competitors use this surface to slide their machines sideways into the bends using the rear wheel to scrub-off speed while still providing the drive to power the bike forward and around the bend.

FIM regulations state that the motorcycles used must have no brakes, run on methanol, use only one gear and weigh a minimum of 78 kg. Races consist of between 4 and 6 riders competing over 4 to 6 laps.

Originating in New South Wales, Australia in the 1920s, there are now both domestic and international competitions in a number of countries including the Speedway World Cup whilst the highest overall scoring individual in the Speedway Grand Prix events is pronounced the Speedway world champion.
Flat track
Main article: A.M.A. Grand National Championship

Flat track racing looks similar to Speedway racing but is in no way related. Flat track motorcycles can have either two-stroke or four-stroke engines in amateur competition. Four-stroke motorcycles dominate professional competition and depending on the venue, can be single or multi-cylinder. Flat track bikes have front and rear suspension, and rear brakes. The brakes are what make it completely distinct from speedway, as the brakes allow for a different cornering technique. Successful riders will often move to road racing, which is considerably more lucrative. Many top American riders in Grand Prix motorcycle racing began their racing careers as flat track racers.[2]

Grasstrack
Main article: Grasstrack

Grasstrack (also known as Grasbahn) racing takes place on a flat oval track usually constructed in a field. It is similar to Speedway with races usually taking place over 4 laps from a standing start. Unlike Speedway, which has 4 riders per race, Grasstrack racing can have many riders in each heat and the circuit is normally longer, allowing higher speeds. The motorcycles are also different in that they have the addition of two gears, rear suspension and are larger in length overall. Like Speedway, the sport uses bikes with no brakes.
Long track
Main article: Long track
Stadion Haunstetten, a Sandbahn track

Longtrack (also known as Sandbahn) is a variant of Grasstrack held on tracks up to 1000 - 1200 meters in length and with speeds reaching 90mph - 100mph. The machinery and rules used are the same as for Grasstrack.

The sport is popular in Germany, possibly more so than Speedway. This means that the majority of tracks are to be found in that country, although tracks can also be found in the Czech Republic, Finland and Norway. Occasionally, Longtrack meetings are held in Australia and the USA, but these generally take place around converted horse trotting arenas.

Ice racing using studded tyres

Ice Racing includes a motorcycle class which is the equivalent of Speedway on ice. Bikes race anti-clockwise around oval tracks between 260 and 425 metres in length. The race structure and scoring is similar to Speedway.

The sport is divided into classes for full-rubber and studded tyres. The studded tyre category involves competitors riding on bikes with inch-long spikes screwed into each tread-less tyre, each bike has 90 spikes on the front tyre and 200 on the rear (or more).

In the studded tyre class there is no broadsiding around the bends due to the grip produced by the spikes digging into the ice. Instead, riders lean their bikes into the bends at an angle where the handlebars just skim the track surface. This riding style is different from that used in the other track racing disciplines. This means riders from this discipline rarely participate in Speedway or its other variants and vice-versa.

The majority of team and individual meetings are held in Russia, Sweden and Finland, but events are also held in the Czech Republic, Germany, the Netherlands, and occasionally other countries.）
