Easy Upgrade

The chain on my 2004 Ninja 250 was getting stiff and worn out so I decided to replace everything and I bought new sprockets both front and back. They were both easy to replace and made of high quality materials, better than what is being sold by other online stores. I'm extremely happy with my purchase and my bike runs smoother than ever now.

cr250 rear sprocket

Nice sprocket. i definitely recommend. great quality and finish. i order a 51 tooth instead of my stock 49 to help gear me down for woods riding and climbing and this sprocket did just that with no problems. perfect fit as well. great product.

JT 520 Rear Sprocket

I installed this on my wife's 2006 Kaw Z750S. I ordered 3 teeth less to lower the rpm's at cruising speed and improve gas mileage. We just completed a 4600 mile trip and my wife was very happy with the reduced vibes and gas mileage. Durability will have to take a while but being a steel sprocket it should last a long time. Very pleased with the results

Solid rear sprocket

Just put this sprocket on my DRZ400S and so far so good. Everything lined up perfect and what can I say, it's steel. Hoping to get a lot of miles out of this one.

fit perfectly

Great fit, exactly the same as the stock sprocket. I'll be back to lower the rating if it breaks or anything :P

Sweet change of gears.......

I pulled the original 42 count rear sprocket and replaced it with a more touring sprocket of 38 teeth on my 2007 Ninja 500R. Fit and finish was very nice and the drop in rpm's was just right. Tooling around on the 500R at 70mph was less buzzy on the foot pegs with the lowered rpm's. The JT-520 sprocket slid on and mounted perfectly and in 25 minutes I was done with the whole project. Sweet.

JT 520 rear sprocket

bought this for a 03 kdx 200. looks nice and after a handful of rides the teeth still look intact. for the money, I would recommend it.

JT steel Sproket

Love the cheap price for a good product that lasts a long time. I used an aluminum one before this and it lasted for about 3 months, this will last me the whole racing season.

Works fine

Seems to be a good replacement for the OEM rear sprocket on my 2005 BMW F650GS. No complaints so far, although I've only had it on for a few weeks. Easy enough to install.
