The Motool Slacker Digital Sag Scale V4 is the ultimate tool to set the front and rear suspension sag on any motorcycle.
This patented system allows anyone to quickly and easily setup their bike’s suspension showing you your unladen sag and rider sag, to tell you if your suspension has the correct spring rates installed.
The new Slacker with Auto Zero also allows you to place the tool in a learning mode so it can actually learn where the zero point is when a bike is lifted.
This is ideal for street bikes as well as dirt bikes when you don't have a stand or are doing multiple bike setups.
All you do is hold the back light button for 3 seconds to place it in Auto Zero mode, then lift the bike to unload the suspension and it automatically marks the zero point so you are ready to take measurements.
