Cant beat this front sproket

Very Good Sprocket. Already passed 10k miles since I installed it and no issues. Will buy again when I get a new chain and rear(which is also Sunstar) in another 10K or so.

Sunstar 525 c.s. sprocket

Installed this on my Suzuki 650 V-strom along with a new DID chain, and changed the gearing from a 15 to 16 to drop the revs a skosh. Went on perfectly and works great.

Good buy.

I'm sure there are better sprockets out there, and I'm also sure they're a lot more money. I read in a couple places that sunstar are often spec'd on OEM bikes, so you know you're getting something reputable. Installed a few weeks ago with a new chain and my bike runs as smooth as ever.

I love making upgrades to my motorcycle that will last. Sunstar is great because it offers factory strength.

Does the job

Put this on my Nighthawk 750 about two weeks ago along with a new chain and rear sprocket. Installation was easy and it is doing the job just fine. I will know better in about 5000 miles how well it wears.

Great Alternative to OEM

Sunstar Countershaft Sprocket

Not much to go wrong with a sprocket. Part seems to be sturdy enough and fits as it should. Installed on an 06 Suzuki V Strom 650. Motorcycle Superstore handled the transaction with their usual ease and speediness.

Great sprocket

Changed my 15 tooth factory to a 17 to bring the rpm's down on the highway and got 4 mpg better mileage. My 2008 GSX 650 F is much smoother now too. After researching I found that my GSX uses the same front sprocket as the SV 650. Highly recommend these sprockets.
