    JT 520 Front Countershaft Sprocket

    Made exclusively from the finest grade of C49 high carbon steel, JT Countershaft Sprockets are made to last with a lifespan greater than any other steel or aluminum sprocket. Each sprocket is heat treated and hand finished to exceed OEM standards, so you get the maximum power transferred to the rear wheel.
    • Designed for 520 size OEM replacements or suitable conversions to 520 size chain and sprockets
    • Outlasts any mild steel or surface hardened sprocket as much as two and three times over
    • Item is bike specific, may vary from photo
    • Item # 7787

    JT 520 Sprocket

    Got this in a 14 tooth for a XR650l to slow the bike down for woods riding. It did the job, but I'm now trying 13 tooth. Overall great product, and at this price you can afford to buy both.

    Feels great

    I had to replace the chain on my '04 Ninja 250. Since this would be my 1st time since I bought the bike, I decided to change both sprockets as well. I went 15 in front, 45 in back - provides a good balance for in-town and freeway use. This sprocket fit perfectly, and feels very well-made; I expect it to show little sign of wear by the time this new chain wears out.

    great sprocket

    put this sprocket on a 2012 ninja 650. went from 15t to 14t. gave the bike a little extra power without too high of revs at highway speeds. sprocket is a lot lighter than the stock one and fit great without any added noise. will probably try 13t next

    Simple and affordable upgrade

    Installed 15-tooth on 2012 Ninja 250r. Dropped RPMs at 70mph by 1000, launch isn't bad at all (although my bike has intake\carb\exhaust mods). Installs just like the factory sprocket did

    It's a sprocket...

    What can be said about a sprocket? It fits and does what it's supposed to do. The price was great and so far it has held up.

    Didn't Fit

    It didn't fit properly with my new RK 520 chain on an 02' SV650S. Not worth the time delay & money to send it for an exchange.

    recommended

    Used to upgrade my stock 04 ninja 250. Quality choice, recommended product. When upgrading front and rear sprockets did not have to replace chain (unless needed).
