15 Tooth Sprocket Does Not Fit TT-R125

Sprocket installs easily, but the chain does not fit between sprocket and engine case. Motosport should not just the 15 tooth as being a "direct bolt on replacement for the TT-R125.

Great sprocket didn't have the holes as pictured which I was hoping for to maybe reduce a little bit on weight, overall so far so good

Gear change

I recently bought a new CRF230F and use it exclusively for trail riding in North Carolina. After my first three trips riding I decided to replace the factory 13 tooth front sprocket with this 12 tooth and I'm glad I did. There's a noticeable difference in 1st gear climbing capability and I still rarely use 5th or 6th gear so any top end loss is irrelevant. I've only had the new sprocket on for two rides so I can't speak to durability but it was easy to install. Only took about 20 minutes.

Sunstar Front Sprocket

I am impressed with the quality of the sprocket, but the manufacturer has mispackaged my 14T sprocket with a 12T in the incorrect package. Motosport is taking care of me though.

Installed 13t Sprocket from a 14t.

Aloha from the Big Isle of Hawaii! So stoked on my decision to change the sprocket on my bike before anything else. Sprocket & S+H came out to only $38. EZ Install! The torque increase is amazing! Top Speed is still the same. Referenced mileage by using Android App, so I -5mph from the speedo. I pack my wife on this for some good distances up hill in 6th gear no problem! Only reason for not rating everything at A+ is that my original sprocket had the rubber sound deadener. There is more chain noise but not a p[problem. Big, Huge difference. Well worth the investment.

Good, Cheap Sprockets

I've been using sunstar sprockets for years and they always seem to hold up well. They are a good value and cheap enough to buy a few countershaft sprockets to test some gearing options for your ride.

Better than OEM.

Great price. Actually gets the chain out away from the case where its supposed to be, versus the OEM sprocket. Which SunStar is OEM from the factory.

Just what i needed

I bought the 12t sunstar sprocket for my CRF450R to replace the 14t the ptevious owner had on for the dunes.
I had heard about problems with 12t countershaft slrockets letting the chain rub the case but i havent seen any sign of it.
Sprocket fit perfect and gave me great gearing. I have been a big fan of sunstar products for several years now and see no reason not to continue using them. The reliability and longevity has been on par with the more expensive parts i have tried

Larger primary sprocket

My KTM 300 XCW came stock with a 13 tooth sprocket. For dual sport riding I wanted a bit more cruising speed without having to wind the guts out of the engine but did not want to go to a smaller rear sprocket. Tried the 15 tooth primary sprocket from Sunstar (price vs. reputation seemed about right). Can run along now at ~40 mph for short stretches of paved road without over-revving the engine (it's a 2 stroke so still need to be careful to not starve the engine of lubrication). Note, the case saver guard had to be substantially filed to allow room for the larger 15 tooth primary sprocket, but other than that was a quick and easy swap. And make certain the primary sprocket is fully seated in to allow the circlip retainer to lock in the groove on the splined drive shaft.

What can any body say about a steel sprocket? It fit. it does what it's supposed to do. Only issue was figuring out witch is the inside of the sprocket.

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?

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

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.
HelicopterMechanic
Over 5 months ago Location: Batesville, AR 72501, USA
A: Depends on how much adjustment you have left. You should get a new chain anyway unless your just swapping sprockets.

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.
