I'm replacing the chain and sprockets on my 98 cbr600f3 and I've decided to go with a 520 instead of a 525. I planned on getting the DID 520vx3 along with the Supersprox 520 steel front sprocket but the only rear steel sprocket I've found is a Bikemaster 520. This leads me to 2 questions; 1) would this sprocket be any good? and 2) what other bikes' sprockets would work on my bike instead?

That rear-sprocket looks decent.

If you have time to research, you can find equivalent Supersprox rear sprocket for even more weigh-savings.

1. look up F3's sprocket dimensions in JT catalogue. Bolt-circle diameter, centre-bore, etc.

2. Look up what other bikes share those sprocket specs, maybe in 520

3. see what else is available for these other bikes, in 520


Looks like SprocketCenter has complete kit:

After doing some quick searching for reviews of Superlite sprockets (the ones that'd come in the kit you linked) I've found quite a bit saying that they've had issues cracking/failing so I'm wondering if they've gotten better and don't have those issues anymore? And thanks for pointing me in the right direction for the rear sprockets, I'm gonna go look and try to find something else that works a little better for me!

 

You're welcome.

I don't have any experience with DriveSystems Superlite, so let's avoid them.

I haven't had any issues with SuperSprox on my CBR600RR. Even flipped it to wear on other side when getting new chain.

Other sprocket outfit is https://sprocketspecialists.com/ . They've made custom alloy rear-sprockets for my Ninja 250 race-bike.

Here's link to JT's sprocket catalog: http://www.jtsprockets.com/downloads/
Link to sprocket specs for F3: http://www.jtsprockets.com/catalogue/part/JTR1304/
Just substitute part# for sprocket you're interested in to get specs & dimensions.


Looks like Vortex has 520 kit too: https://www.sportbiketrackgear.com/v...BoCWLMQAvD_BwE
CycleGear has Vortex 520 aluminium F3 sprockets: https://www.cyclegear.com/parts/vort...sprocket-honda

 

Thanks for all the links, I'm gonna look into finding sprockets from different bikes that'll work on mine as the vortex kit changes the gearing and I'm mostly wanting to keep that stock. I've been able to few aluminum 520 sprockets however I've really been looking for a steel one just for longevity. If I can't find anything then I think I'm gonna go with the bikemaster sprocket as a last resort or I might just resort to keeping it 525, but again, appreciate the links and the information!
