Slacker Digital Suspension Tuner
Works on dirt bikes, street bikes, and adventure bikes. For MTB click here.
When your suspension is dialed, everything becomes effortless. Slacker gives you instant, accurate sag readings right on the handlebars so you can tune your bike to perfection every ride. No helpers, no guesswork, no more wasted riding days.
Slacker is a patented system that mounts to any motorcycle or mountain bike in seconds and streams live sag measurements straight to your bars while you are mounted on the bike, using our optional wireless remote or the free Slacker Virtual Remote app. Simple, fast, and precise! It's the only way to properly set up your suspension on your own, whenever you like.
Directions For Use
Just stick Slacker on the axle using the super-strong magnet, connect the retractable cable to the universal clip, and turn it on. Now turn on the wireless remote, or connect our Virtual Remote app so you can see your readings while mounted on the bike! It could not be easier to take real-time measurements, with absolutely no assistance.
Includes all the required attachments for dirt, street, and adventure bikes to measure the shock and forks. MTB requires the optional Virtual Fender Mount to measure in the rear.
Requires (2) AAA batteries - not included.

"I bought this so I can fully dial in my two bikes. After months of no riding because of the harsh winter we had here in the northeast and suffering a really bad crash that left my wrist fractured, and broken ribs, I was excited to try it out. While I was hand tightening the virtual fender to the bike the little flimsy bolt that holds it cracked now I am left with an expensive paperweight. Really disappointed."
"High quality kit with everything you need to accurately set the sag on the front and rear shocks. I was surprised at how far off it was using weight formulas to estimate shock pressure to set sag. After setting the correct sag with the slacker, my bike rides so much better—more active on climbs and plush on the descents!"
"Purchased the Motorcycle starter kit to set sag on my dirt bikes. I've been using a tape measure previously to do this. The Slacker tool makes it so much easier and faster. Using this tool, I feel much more confident in the adjustments I am making and i dont need a second person to assist me. The instructions are very easy to follow and the tool works seamlessly."
"I love my slacker but my old one broke out of nowhere. Called about service was told to send it in and they will repair. Good thing I ordered another since my broken one has been there for 2 weeks. I love the product but idk about the quality."
"Good idea, smart execution. . Device feels robust, easy to use. Megnet to attach the tool on the rear shaft. You're done realy fast. Some extra self adhisive connecting point for the rope / wire were with the tool. Actualy nothing negative to tell anyone. Only,,,, throw in the battery's when packing the tool for shipping. Than you can get going when you receive the tool."
"Makes setting up the slack so easy, especially when alone. And with proper set up slack, the rebound and compression follow so easily and convenient. A properly set up bike makes such a difference, one wouldn’t believe it. Honestly, it’s addicting how rewarding the before and after is, I’m gonna set up every friends bike I can get my fingers an."
"I was surprised how inaccurate the shock stroke measure method was. Nearly a 7% difference in sag percentage on my bike. Which I suspected because I felt like I was too deep in the travel and this confirmed it. Note: this wheel movement measurement is not a holy grail, it’s a starting point to tune from. My 2 gripes are: the temporary fender required ALOT of strength to tighten the swivel point not to move. As soon as the tension loaded string was attached it pulled down. And the axle inserts could be a little larger in diameter. If I dismounted on the brake side, the weight of the device would pull it out of the frame. With the newly revised phone App, I did waste money on the remote but no big deal"
"This thing is so awesome and makes like way easier!! I love telling everyone about Slacker & showing them just how easy it is to tune your suspension with no assistance!!"
"Tool is simple to use, comes with everything needed for motorcycles (except batteries - wish there was a lithium rechargeable device version). Phone app works well, no issues. Very accurate and enhances safety. Purchase to do it yourself and save money from the stealerships. Only thing noted that I hadn’t seen mentioned is if you have rear axel spool sliders (for paddock stands) you may have to remove in order to attach this earth magnet to your rear axel. You may not be able to use your rear stand if spool has to be removed. Great price, great product, highly recommend to other. Device that pays for itself! Awesome."
"I placed an order on a promo deal that said it included everything plus the case and remote. The kit came, but no remote. Reached out to customer service who kindly sent the remote after a few short questions. The tool is super straightforward and easy to use and if taken care of should last any amount of slack adjustments performed from moto to mtb!"
