Poor sprocket choice

This aftermarket sprocket is heavier than the oem. The picture shows a nice cut out sprocket, the Sunstar sprocket I actually received is one solid steel piece. Even the oem Yamaha R6 sprocket has cuts to make it lighter. What is this? Happily returning this item.

This purchase is very good when replacing OEM, or updating. Very happy with sunstar so far. Only a few rides on this Sprocket. Motosport shipped it very fast to me and was able to install myself. Good product.

2018 Yamaha XT250 gearing nearly perfect

Purchased a 45T rear a few weeks ago (stock is 48T) - noticeable improvement
Purchased a 16T front a few weeks later (stock is 15T) - near perfect gearing at this point (for me anyway).
Would drop to a 42T rear if I could find one

Out of the gate!

Just put on the sunstar 13T front sprocket. After a quick ride I noticed a big improvement in response. It did shorten gears, but there is no stutter when getting on the throttle anymore. Quick and simple to install and adjust the chain.

Works as it should.

I bought a 13 and 14 tooth front sprocket to switch between ratio's for my rides based on the terrain. I'd suggest that everyone buys both!

Exactly what I ordered.

Ordered, came to my door, and was correct! Exactly what I ordered. Already on the Vstrom and 1200 miles on the clock.

2014 Suzuki Vstrom 1000 ADV. With new chain and sprockets from Motosport.com.

Simple solution to my Ninja 400's highway problem.

This sprocket (one tooth larger than the stock one on my 2018 Ninja 400) reduced my highway RPM's by 500 and made my commute a pleasure. It fit perfectly, was under the 8% change that causes the check engine light to come on, and was a very inexpensive solution. I was actually thinking of trading in my 400 (with 128 miles on it) for a 600 before this saved my bank account!!!

Q: Is the ten teeth good for a kx250 1997 or will it not fit well

A: This will fit your bike, however, anytime you are going down in teeth in the front you must go up in the rear that is if you are attempting to achieve more power on the bottom end of your torque band.

Q: I know when trying to get better top speed to drop teeth on the rear sprocket but how about the front? drop or add teeth on the front for top speed
2 years 5 months ago
currently my top speed on my Honda 300ex is 65 and I want to get that faster and I know I need to drop teeth in the rear but I'm not sure to add or drop teeth in the front.

A: add 1 tooth to the front, be careful of clearance issues with engine case
HelicopterMechanic

A: Faster = front sprocket bigger and rear smaller. One tooth on the front equals about five on the rear.

A: Going up teeth on the front sprocket and/or down on the rear will add top speed.

A: Check this link out, there's a great chart at the bottom of the article that shows the smaller change with rear sprockets compared to the front sprocket. Hope this helps.

Q: Will this fit my 03 z400 and if I get the 13 tooth front and keep the 40 tooth rear can I keep stock length chain

A: Depends on how much adjustment you have left. You should get a new chain anyway unless your just swapping sprockets.

A: All aftermarket chains come in a generic length and need to be cut to fit. You will want to do this on the bike with a chain breaker tool to make sure you get the correct length needed.

A: Probably but youll have to run without the case guard. That big of a gearing jump you may want to look at making the rear smaller.

Q: Chain 530 or 520 for this sprocket couldn't see it anywhere
Over 4 years ago
Is it a 520 or 530 didn't see what it was so curious
MotoSportGrantK
MotoSport Staff
Over 4 years ago
A: If profiled for your 2012 Suzuki Hayabusa, it will be a 530 sprocket so you will need to use a 530 chain. A 520 will not work.
