e/Jockey shifter

Information
has gloss	eng: The jockey shifter is a gear shifting device used on motorcycles before the use of a foot-operated shift lever. A jockey shifter also known as a slap shifter gets its name from the location of the motorcycle riders hand when shifting gears, it is under his seat like the position of a jockeys hand while using his riding crop on his horse. This hand shifter lever is directly mounted to the transmission and is just long enough to clear the primary drive cover or belt drive. A motorcycle equipped with this type of shifter requires the use of a foot clutch. The foot clutch comes in one of two configurations; either a rocker foot clutch which was stock on many early motorcycles, or a suicide foot clutch which was never available on production motorcycles but was manufactured by daring motorcycle enthusiasts.
