    The 52T rear won't fit a Yamaha Warrior

    The 52 tooth rear sprocket will bolt onto the place it is supposed to, however the chain guide's steel bracket is so close to this sprocket that it won't allow for chain adjustment, making it impossible to use the 52T sprocket. I suppose one could use this but it would require cutting and welding the chain guide mount and fabricating a completely new chain guide. I'll use it on my 1981 YZ250 instead since steel JT sprockets have always given me good service.

    Mod sprocket for baby Ninja

    I installed JT 42T 520 pitch rear sprocket in my 250R to reduce engine workload at highway speed. It worked perfectly, looked nice and priced right. Could not ask for more. I put in 600 miles in 2 weekends, performance was admirable. Smooth and quiet. My engine reved 7000 rpm at 70 mph indicated speed. When ready I will get another front sprocket to fulfill my wish for this baby. Way to go, JT.

    Great Sprocket

    Really, what can I say? It is a rear sprocket, and seems to work great. I've a few thousand miles in it and it still looks new.

    JT STEEL SPROCKET

    I bought this for my 2012 DRZ400S Fit is perfect. The color matches the bike. "BLACK" I got the 41 tooth for better MPG and less rpm's at 50 mph. It has worked like a charm. The DRZ is not revving high in 4th gear at 45-50 MPH. I also replaced my chain which I took two extra links off for the smaller JT Sprocket. FIT IS PERFECT.

    JT STEEL Sprocket

    Real nice surprise to see the JT Sprocket was Black. I ordered a 41 tooth for my DRZ400S. Wanted more top end. Replaced the chain with a new one. Took two links off normal length. Fit like a glove. Hope this helps out. I was tacking out 4th gear, or lugging 5th. To do 50 mph. :(This will make it a dog out of the hole): I ride dirt maybe 10% of the time. So the change will be good for my commuting ride. Hope it will save the motor a few rpm's on the ride to work and back.

    30T for Honda Rebel 250

    Wow, this 30T sprocket made my Rebel so much smoother through shifts. I can actually travel more than 3 feet from a dead stop before shifting into 2nd. I'm 5'11" 180lbs.

    JT rear steel sproket

    One of the best steel sprokets I have found. I always run a steel JT on my 2006 ktm 250 stroke. I just wish they have more teeth choises, it goes from 45 then jumps to 49 teeth I need a 47 but it still works well. But I always get a diffrent sproket then in the picture it look like the sunstar sproket but it black but i still like it.
