Hi guy's,
I just bought my versys 300x, and i want to replace the front sprocket to 15t.
I searched all the web for a rubber 15t that fits the 300x but i dont find it anywhere.
Any clue where i can buy it? And send it to Israel?
Thanks in advance
David

The X300 puts out 39 (ish) horsepower. I had a very long discussion with a Technical Staff member at J.T.Sprockets and covered the concern of the thinner JT565 series sprocket compared to the stock. (5.8mm wide instead of 9.3mm wide for OEM). As that is a difference. The staff member assured me that the X300 is not a concern as the JT565 sprockets are factory on bike up to a full liter bike (1000cc). The shaft and sprockets are hardened and with correct installation to assure no movement at all there is no way the X300 bike will have any effect using the thinner sprocket. I've had my JT565 sprocket on my bike to 1/2 season = over 2000 miles and no issues at all. The X300 is nowhere near the limit of the parts. I was assured of this from a very knowledgeable J.T. Sprocket technical (engineer actually) person.

Thanks, this question has been on my mind as well. Since I do a lot of stop-and-go in the city while commuting, I'm constantly having to bang through the gears, so moving to a 15t seems like the best solution. I will go ahead and order the parts based on your threads and videos.

Great work, thank you.

@Dave 300x Thanks for taking the trouble to put all this together. I'm a little confused about your link to the Dennis Kirk for the Sprocket? The model check on the webiste says "Item DOES NOT fit your 2021 Kawasaki KLE300C Versys-X 300 ABS" Am I missing something?

That is correct. The website assumes you are looking for a drop-in replacement sprocket and the 15t rubber-bumpered sprocket will not work as a drop-in, hence the warning and the need for the additional washers.

Just finished installing the rubber bumpered 15t sprocket using @Dave 300x 's videos. The installation went really smooth, no issues at all. Took about an hour, but a good chunk of that was making sure the chain was aligned and tensioned correctly after the sprocket installation. Thanks Dave.

The bike feels so much better now, this is probably the best upgrade one can do to the x300. The bike doesn't have that stressed feeling at speed anymore. Took it for a quick spin and in 6th gear I'm showing ~7,200rpm at 65mph (~105kph) indicated and ~8,400rpm at 75mph (~121kph) indicated. At both speeds the bike felt relaxed and my TBR slip-on wasn't roaring as it usually does at these speeds. The bike felt really happy and quiet doing things like cruising down my road in 4th gear, when I normally would run it in 5th-6th to keep the noise down a bit for the neighbors.

As of this post, the JTF565.15RB front sprocket is 25% off on Amazon, just a heads up in case anybody wants to grab some extras or is looking to make the conversion.
