Virtual Remote Display

The new Slacker Virtual Remote (shown here with optional smartphone bar mount) is now included with our Service Assistant app for iOS and Android. Now you can use your phone as a remote display, and save measurements directly to your setup notes. The virtual remote also allows you to reset Slacker to zero and place it in Auto Zero mode from your phone.

The optional Slacker Wireless Remote extends Slacker's primary display and button functions so you can always have a remote, regardless of whether you have your phone or not. It can be used in tandem with the Virtual remote for simultaneous, multiple display options or as a dedicated remote for those who just want the basics.

Easy to use and accurate. I like the app and the fact that you can review previous settings and log more than one bike

Was able to make suspension adjustments to my dirt bike by myself with amazing results. Big difference how the motorcycle handles. I recommend for purchase. 4 stars now due to their app needing money to keep using it.Sorry everyone. Research a little. There is a Slacker virtual app that works very good. Back to 5 stars for this product. The toll is really good it was the wrong app I had iasues with.

The main reason I got this is that I'm allergic to asking for help, and I just wanted to be able to check sag by myself–so I don't ask much of it and it certainly delivers. It offers a lot more capability beyond that, though.Instructions were pretty good and there are lots of videos out there to augment. Note that in order to get an initial zero, you will need a way to get your rear wheel off the ground with the swingarm unloaded: either a center stand, track stand (dirtbikes/lighter dual-sports) or get creative with ratchet straps and rafters (or something).I managed to confuse myself re. the "auto-zero" feature but quickly figured it out. The app (iOS) is pretty well-designed and uses BTLE to connect to the unit, so no need to pair or otherwise futz around; for me, it just works. It allows you to save "profiles" that are incredibly detailed with a few dozen parameters, but you can just set the ones you're interested in. I like that all the fields are just text and don't enforce a particular format. I created a "base" profile with stock settings. Any time I make a change, I'll duplicate the last profile I used, test it, then add notes for how it felt. It makes it very easy to keep detailed records of every adjustment I've made, and a guidepost for getting back if needed. Plenty helpful for a weekend amateur like me, and could be very useful for a more serious competitive rider who might (for instance) work up a profile for each track they ride, or even for each track/condition combo. You can really go as granular as you want. I wouldn't mind an option to hide unused fields (which is most of them in my case) but not a huge deal.It's nice that they give you multiple options for attaching the cord to your bike. The fender clip worked well on my dual-sport.All in all, very satisfied with this product and would recommend it to others.

Setting SAG has never been quicker or easier. Use free phone app to see readings. Do it yourself in all your gear for accurate weight. Right after a ride so the oil is hot. Used on multiple bikes. Dirt to street and track. Awesome tool.

Although much more expensive than a tape measure, this device is a real time saver -especially if you don't have someone else to help you set sags (which is the case for me a lot of the time). Or if you need to set sags often (when changing suspension for different tracks or track conditions) this device makes it quick, easy, and accurate.

A bit expensive but very happy with this purchase, the phone app works with the V4 well soo far and removes the need for some of the extra displays which helps keeps the cost down. I now take all the time I want to setup the suspension solo without a struggle and don't need a friend or helper standing around waiting to help (especially when it's midnight the day before your next trip). Would recommend this investment to anyone setting up or tuning their own bikes.

This is a must have item for setting sag on your bike. The time savings is worth the cost in that you can make adjustments in real time and by yourself.Add the Bluetooth readout and carrying case and you will not be disappointed. See in real time how just moving forward and bike on your bike effects your suspension.This can also be used on street bikes and mountain bikes as well. Get your suspension set to your rider weight for optimum suspension.

Haven’t used it yet, but everything came as described and looks good. Delivery was fast. Unfortunately I had to pay duty fees which I wasn’t expecting.
