Easily the best cost effective change to a KTM 390 ADV, and possibly many other bikes.
Worked perfectly with my 2023 KTM 390 ADV. Gives the bike more low end torque and eases clutch engagement feeling significantly. Honestly this is an easy install, and I cannot go back to a 15 tooth sprocket afterwards. This completely changes the torque feeling at low speed and makes riding at low speed easier on and off road. If you want to wheelie this will definitely help as well. There are a lot of very expensive mods you can do on a KTM 390 from a full exhaust to air intake/filter, and fuel maps/ecu mods, but this should be your first. Not only is it the cheapest of all($18), its also the most effective. JT Sprockets has been around for a long time, no worry here.

Best Upgrade for KTM 390 Adventure
I installed this 14T sprocket and was blown away! The bike leaves stop signs and stop lights with EASE compared to the stock 15T sprocket. The bike is peppier, and way more fun to ride. Size differences are shown in the images. Only downside was the loss of close to 10 mph on the top end.... but who needs to go over 100 mph? I now easily cruise at 80 mph with the tach at 8k rpms. Best 390 purchase ever. Installation is easy and if this is the only addition... your stock gear will work perfectly, just adjust your chain!

Solid item
Went down a tooth on a Svartpilen 401. Doesnt have the dampener rings like stock sprocket but i cant really tell. Gave a little more pull down low to mid. Overall happy.
