Hey Everyone:

Just bought and 03 rr and the first owner installed a 520 conversion on the bike with DID ERV chain. To tell you the truth I am not sure what this really does. I know that it makes the bike quicker off the line but Im not sure if this is something I should keep on or change back to stock. I also have the stock sprocket and chain as well.

Is this too much power for a beginner or should I just leave the aftermarket parts as is? Any feedback would be appreciated. Thanks.

 

just leave it
are the sprocket teeth the same?
in that case you wont notice much of a difference at all.

if the teeth are changed it will take off a little quicker but just dont crack the throttle open and you will be fine

kinda like a firearm
its only as safe as the person pulling the trigger

 

Stock chains are 525, the 520 is a conversion kit that many people do. The 520 is a narrower chain, and comes with 520 matched sprockets which you have on there now. Basically what the 520 does over the 525 is that is lessens the rotating mass of the bike, and makes the bike more responsive. It has the same effect that putting lighter wheels on the bike would have, just on a smaller scale. If its on there now, then leave it. Personally I am not a fan due to the fact that it typically needs to be tightened more frequently, and is more prone to snapping due to the fact that its less metal, and unless its a really high end one, probably isn't as strong as the 525. My buddy on an SV1000 just had a chain snap, and he is now looking into a new engine cause the chain cracked the engine cases on its way off. If you are racing on a track then its worth it, but on the whole its really somewhat unnecessary for street riding and the like. And if your going to be clutching wheelies, then be careful, added stress under those conditions can lead to breakage. Like the previous threat stated, if you switch back you wont really notice a difference unless the gearing was changed,,, but thats a whole other topic of discussion.

 

pretty true stuff
especially the part of the high end chain

as long as you get quality like the DID ERV3 chain you will be fine.

i have had this chain on my 1000rr for 5K miles and only had to adjust it once.

it will be fine for the 600

 

did is pretty much the best you can buy, dont worry about it snapping as long as you adjust the chain, and lube it... you do know you have to do those two things right?

 

I recently did the 520 conversion (stock gearing) with new sprockets. To be honest, couldn't really tell a difference. But, less rotating mass is always a good thing. (not to mention a high-end 520 conversion kit is usually cheaper than the stock chain and sprockets.)

 

yeah with stock gearing and street riding you wont notice much of a difference. on the track at high speeds the lower rotating mass will help with cornering.

 

^^ Guess that's my excuse for blowing more student loan money on a track day. My excuse for using it would be "I'm conducting a study to see how the effects of less rotating mass equates into higher maneuverability on two-wheeled machines." I think I'll get away with it.
