Easy to install... If you have the proper tool

This front sprocket is a great product, very durable if you also renew your chain. Replacing your front sprocket with a bad chain will rapidly increase wear and your sprocket will not last nearly as long as if you replace your chain, this also goes hand in hand with the rear. That is why it is recommend to replace all at once. Also, I highly recommend that you buy the tool for it if the bike is a Kawasaki mini or a ktm mini. These bikes all have the clip, which if you do not have the tool to pull it off can be the biggest pain to do. Overall it is a great long lasting sprocket, but just make sure you have the tool.

Renthal makes proven durable products. Have not had a Renthal sprocket fail on me. Like any front sprocket, they are steel and offered in an array of sizes to fit your gearing needs.

Q: How to reduce torque on a 2011 KTM 50sx?
2 years 1 month ago
Currently running a 10 tooth front sprocket and 42 tooth rear sprocket. Which one should I change to lower the torque on the bike. Daughter gets jerked when she gets on the gas.
MotoSportExpert
MotoSport Staff Expert

A: For less bottom end power and more top end you would want to go down on the rear sprocket and/or up in the front. Remember 1 tooth in the front is equal to about 3 in the rear. Feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.

A: To reduce torque (spread out the gearing) you would want to increase the size of the counter-sprocket (front sprocket connected to engine, sometimes called the drive sprocket) or decrease the rear sprocket (Large sprocket attached to wheel hub, sometimes called the driven sprocket). Keep in mind the bike will accelerate slightly slower but will also have a higher top speed. Another thing to consider is you may want to stick to changes on the sprocket, not counter-sprocket. Counter-sprocket changes are BIG changes and you can get much more gradual changes with the driven sprocket.

Something else you may want to check before changing gearing is the chain tension. You say the bike jerks when she gets on the gas, that is usually a sign of a loose or stretched chain. Be sure to adjust this to the manufacturer recommendation with is usually about 1" to 1 1/4" of free play.

Q: Would changing the sprocket size on a 07 ktm105sx help with trail riding?
2 years 1 month ago
We trail ride the most and I know a trail bike would be better overall however we like the weight and size of the 105. Would changing the sprocket size set the bike up better for trail riding? Any recommendations on a good ratio or size for front and rear. I believe the stock size is 14 in the front and 49 in the back.

A: Yes you can definitely gear your 2007 KTM105SX to work better on the trails. Going up on the rear and/or down on the front will give you more bottom end. I would recommend searching the forums to find out what gearing is working best for trails on the 105SX.

Q: Best setup for mx front and rear sprocket?

A: Motosport.com only list the stock gearing for your Yamaha YFZ450.

As a general rule of thumb to get more acceleration (less top speed), you will want to either drop teeth in the front or add to the rear sprocket.

To increase top speed, you do the opposite.

Q: If I have a 13 on my bike and a 53 on the back if I do 12 in front and 52 on back will I have more touque and more top end at the same time?

MotoSportGrantK
MotoSport Staff Expert Top 1 Contributor
2 years 10 months ago
A: You can either gain acceleration or top speed, not both. 13-53 gives you a gear ratio of 4.08, going with 12-52 will give you a gear ratio of 4.33 giving you more slightly more acceleration and less top speed. Also, feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.

A: No.

It is impossible to get both more torque AND more top end with sprocket changes. The only way to accomplish this is to change the bikes transmission gearing (1st gear ratio, 2nd gear ratio, and so on) and even with this you could only accomplish more torque on the bottom and more top end in the higher gears.

It is a give and take. With sprockets if you want more torque you sacrifice top end. If you want more top end you sacrifice torque.

I hope this helps.
