Put a sting in your 2010 Z1000's tail

SCORPION has released an all-new new silencer for the 2010 Kawasaki Z1000.   The slip-on silencer requires no additional modifications: bolt on and go.Consistent power improvements throughout the rev range have been seen, with no adjustments to the fuelling, say Scorpion, with an average increase 3bhp.The new silencer has been acoustically developed to provide a greatly enhanced engine note.  This means the bike will be as loud as the original in terms of a dB reading, but the exhaust note offers a deeper growl. However, removable baffles allow the rider to dramatically alter the tone of the exhaust by simply removing one bolt per silencer.

AMA Pro Racing Announces Basic Twins Flat Track Class for 2014 Season

AMA Pro Racing announced a new class for Flat Track racing designed to provide a new stepping stone for up-and-coming Pro-licensed racers, replacing the Pro Singles class in 2014. The new class, to be called Basic Twins, is more or less a revival of the Basic Expert Twins division that ran during the 2007 and 2008 seasons, but dropped when the Pro Singles class was introduced for 2009. The new class will give young racers a chance to showcase their skills on Twins, easing their transition to eventually enter the Grand National Expert Twins class.
