Motool Slacker V4 Bluetooth

Set your race sag properly, on your own, in seconds.

The Motool Slacker is the digital sag tool the paddock actually uses. Clip it to the axle, sit on the bike, and the measurement appears on your phone over Bluetooth while you're still in the saddle. No tape measure, no second person holding the bike upright, no guessing between motos.

Why sag is worth getting right

Race sag is the single cheapest handling change available to any rider, and the one most people never set correctly. Too much and the bike runs low and vague at the front; too little and it stands up and deflects. Ten minutes with a Slacker will do more for how your bike turns than most parts you could buy for the same money.

What it does

• Measures rider sag and static sag directly
• Live reading over Bluetooth to your phone
• Works solo — no helper needed
• Fits MX, enduro, adventure and street bikes
• Repeatable to the millimetre, so you can log settings track to track
