520 conversion

Hey guys, just wanted to get some opinions on doing the 520 conversion. I'm not planning to put the RC on the track that often, so is there any real benefit of doing the conversion? I plan to get a dedicated track bike.

Lighter weight where it counts. With aluminum sprocket it save a fair bit but aluminum wears faster. Just stay on top of chain adjusting, lubing and cleaning. I have had my Driven 520 quick acceleration kit on for 2k without issue

I just replaced my 520 set. I got a DID and alum rear AFAM and Driven steel front. 15/42. It's an exact replacement for the last set that I got somewhere around 20,000 miles from.
This set-up is about 2-1/2 lbs. lighter than the steel 530 OEM. And that's rotational mass.
Definitely keep up on your chain slack and lube, but I wouldn't ever switch back to OEM for street use. I have no idea about track.

Is there any other benefit from the 520 conversion besides weight loss?

If the 520 kit is a high quality kit it will generally outlast most OEM 525 or 530 chains if properly maintained. That's more of a by-product though of simply having a superior product installed as the main goal is weight savings. A typical 520 conversion from a 530 kit with an OEM steel rear sprocket usually saves about 4lbs of rotational mass which is quite a bit.

I gotta ask you if you weighed them to actually see the difference. I contend that there's about 2-1/2 lbs difference over a stock steel 530 set. Not 4.
I weighed my old set, it was about 4-1/2 lbs. Anyone know what a stock set weighs?
