Runs cooler.Runs much cooler than the Shunt voltage regulator rectifier.Saves gas.Less load on the stator, less work, less is used and you save.Extended battery life.Extends the batterys life and cold cranking capacity.More engine .Removes stator load resulting in more engine . With enhanced technologydesign.All item pictures are , if in doubt do not hesitate and compare our item to your original part. With enhanced technologydesign.This product is an advanced design lowers operating.STOP BURNING YOUR REGULATOR RECTIFIER !In addition, this rectifier has overheat protection, rather than burn up it will simply turn off for a while and cool off.Direct replacement to your original unit.Plug-and-play, direct fit, easy installation.Improved heat sink and charging capabilities Higher grade of electric components.We have even included the opposite connector (main harness side) as we know these are often melted corroded defective and a major for repetitive electrical issues. Before installing your new regulator/rectifier:Check the AC output of the stator.Replace any burned or corroded connectors on stator and regulator/rectifier.Check and repair any melted wiring. hi-temp on all connectors. for Vehicle models fitment 1098 -- 2007-2008 1198 -- 2009-2011 749 -- 2003-2007 848 -- 2012-2013 848 Super Bike -- 2011-2012 999 -- 2003-2007 Multistrada 1000 -- 2003-2006 S 1099 -- 2009-2012 600 -- 2004 650 -- 2005 955i -- 1998-2006 Speed Four 600 -- 2002-2005 Speed Triple 1050 -- 2005-2012 Speed Triple 955 -- 1999-2004 Sprint 955 -- 2000-2004 Sprint ST 1050 -- 2005-2012 Sprint ST 955 -- 1999-2004 1050 -- 2007-2012 955 -- 2001-2006 part replacement T1300560 540.4.019.1A 540.4.027.1A Other specifications : Number of plugs: 2 Number of pins: 7 Number of wires: 7 Minimum Charging Voltage: 14.5V +/- 0.5V Maximum Charging Current: 50A/500W Open Circuit Voltage: Less than 15V Operation Temperature: -20 Celsius to 85 Celsius colour:black Material:metal size:Width: 90 mm Length: 94 mm Height: 30 mm Fixation holes center to center: 75 mm Wires Length: 320 mm & 235 mm Package Contents: 1* commutator Only the above package content, other products are not included.
