Hello,

I've been researching for the past month and half on my chain upgrade. I've searched and learned but there are a few things I still am curious about. I'm looking into doing the infamous 520 conversion with -1, +2 change in sprockets. I've heard mostly good things. However locally I've been told that a smaller front sprocket increases the angle in which the chain turns and causes the chain to pre maturely need replacement. I'm wondering if there is any truth to this. It makes sense. I'd like to know if its even worth taking into concideration.

Also, locally people are very negative towards 520 do to weaker parts. I've personally seen a friends rear aftermarket sprocket warp and have the chain jump. Given it was a vortex sprocket and I'd put money on the fact that the chain wasnt properly maintained. I'm just wondering if this is any type of common.

Thanks for your help and time.

I'm not a professional on the subject, so don't take my word as law. But, some things I've learned since joining the motorcycling community:

1) Vortex sprockets are crap
2) The 520 is a thinner than stock chain
3) This thin-ness might be a problem with the liter bikes, or those making gobs of power
4) But shouldn't be a problem for the vast majority of 600s
5) Most Importantly - Proper Chain maintenance is crucial to the life of a chain

My brother has a 2006 R6 same as mine. He went -2 in the front 2 years ago and has never had a problem with it.......

I'm running -1 +2 with vortex sprockets and a DID chain. I've got 3000 miles on them including track, canyon, and commuting. Everything looks fine, I think the most important thing is maintanance and keeping the chain well adjusted.

I've done the 520 -1/+2 and i've all for it. I have the vortex rear aluminum and that thing is super light, i thought it was going to rip in half one i hit the throttle, but it seems to be holding up fine.

It said to adjust the chain after 10 miles, but mine didn't stretch until after like 150km, then i adjusted it and it's still good after about 1000km.

Sure it might involve a little more maintenance, but the pros outweigh the cons by a long shot.

Dont know where you heard Vortex sprockets are shit from... but I tend to disagree. The only sprockets, besides one conversion, that i know of has used Vortex sprockets without a hitch. The other used renthals.

I wouldnt think the chain turning around a sprocket would be bad for it, it doesnt get enough angle between the links to damage it, unless you run like a 12 tooth, then maybe

I've heard just about everything from Vortex is low quality stuff. I got a set of sliders thrown in from the dealer when I bought my bike. Some things got messed up, and it took like a month before I received them. So, I bought a set of Motovation sliders and the Vortex's hardly have any material in comparison.

I dunno, I'm not saying they make complete crap, it's just I've heard bad things about them... especially their sprockets. Too many horror stories of sprockets failing and chains ripping into the engine block for my liking. Heard nothing but good things about AFAM sprockets, Driven sprockets, and Renthal sprockets though

A smaller front sprocket DOES make the chain bend more, causing it to wear out faster.

Short answer is "yes." But then if want the benefits of lighter weight and less drag, a 520 is good for racing.

My 2 cents, anyway

Short answer yes. Long answer... Not enough to turn me away from doing a 520 Upgrade. The maintenance is KEY in that factor too. I have done sprocket upgrades on a stock chain and I have done sprocket conversions (to a 520 kit) I ran my stock chain and sprockets about 6000 miles then I ran my stock chain and -1 +2 sprockets for another 10,000 miles with NO Problems. Decided to upgrade to a 520 setup at 16,000 miles and have put about 8,000 miles it it also with NO problems what so ever. Maintenance for a chain is CHEAP! Lube it every 400-500 miles. if you keep it lubed, it will stay flexible... and it will wrap around any sprocket (of the correct size) that you put it on.
I also second the motion of VORTEX SPROCKETS SUCK. Only because I have a buddy that bought their stuff and KILLED IT within a month. Brand new everything too, and it was all installed right, nothing out of the ordinary... rounded them teeth PRONTO!!!
I think thier stuff is probably good for the track (quick, hard use, and replace) but not for lengthy uses.
Oh well... If you're looking at sprockets and stuff. Go here Link www.sprocketspecialists.com or CALL THEM. If you have any questions they will be able to answer them. I have been using their stuff for over 3 years, and NEVER a problem. Their web site is kinda whack, but their products are INCREDIBLE (quality and price) I recommend them to EVERY one I talk to about sprockets.
Oh well... That's all I got man. Hope that I have helped you out some.

If you go to a front sprocket of 15 teeth instead of 16, you'll wear the sprocket out 6.25% faster, however, most chains outlast sprockets with proper maintenance, so why worry about the chain? Instead of 20k out of a set of chain/sprockets, you'll only get 18750 miles out of it. Really not that big of a deal. As far as the angle goes, it has nothing to do with it at these sizes. You only wear it faster because the output shaft is spinning faster for a given speed, so it takes more teeth to go the same distance, meaning more chain wear. The smallest sprocket I know of for these bikes is an 11 tooth from sprocket specialists, and you can safety run that for quite a few thousand miles before needing to be replaced.
