Hey guys,
first of all I want to thank everybody who helped me with my research I love this forum I just placed an order for chain & sprockets kit for my 05, F4i (25k miles). I bought it for Motomummy (free shipping), otherwise Hard racing had best price (but + $12.75 shipping).

So I ended doing the 520 conversion - getting "All Steel (both)" Driven sprockets with EK MVXZ chain (rated 1000cc in Black color) for $175 Total delivered. Did I do good or bad? Or could've done better ?

Thanks!

 

You did fine but just a question? why did you go for a 520 conversion and stick to a steel rear sprocket? And I do like Hard Racing they go out of their way to get you want you want/need.

 

Probably because its a street bike....Why wouldn't you do a 520 conversion and use steel sprockets? I used to go threw 2 renthals for every one chain [that 2 sprockets and 1 chain for 20k miles], now I go threw 2 chains for every set of sprockets [thats one set of sprockets for 40k].

Op- I'd say you got a fair deal.

 

I was asking because of the difference in weight (albeit small), most people swap to 520 to drop weight, so why go with steel sprockets? I'm not saying he is wrong, I'm just looking for insight in his decision and his reasoning.

 

When I went from 530 to a 520 conversion recently I stay with steel sprockets because I heard they last much longer. The weight difference wasn't all that much. I carefully weighed all the old parts and the new ones. The difference was 12oz. That's not a whole lot when you consider the bike weighs over 400 lbs.

 

Ok but what prompted you to switch to a 520 chain? And sorry OP on hijacking your thread.

 

The 520 conversion kit is popular on one of the other forums I'm on. I wanted to experiment with different gearing by going -1 in the front. They also said it would be lighter, although I didn't know exactly how much lighter until I weighed it myself.

 

Yea I came to about a 100 gram difference between steel/alum and 520/530. I just wonder what others think about it.

 

I prefer 520 because yes its lighter weight but more importantly its the most common size used which makes 520 chains cheaper then 525. 520's are availible with much more strength then an f4i will ever need and have proven [to myself at least] to last as long as 525's so why not.

 

No problem.

My reasons:
1. I could get an Average 525 chain + some heavy sprockets in a cheap/mediocre brand for $150-$170 range (shipped) no-name brand, just cheap kit. Driven (quite popular sprockets) and EK (MVXZ) also very popular -1000cc bike chain.......strong & high quality for the same price as a mediocre 525....so why not?
2. A higher quality 520 is the same price, and a higher quality 520 would last longer, than the mediocre 525, so why not?
3. Though i don't need it, it would give me satisfaction/comfort knowing I'm riding the same chain/sprockets kit that a 1000 bike has.
4. Now if I get any weight savings too, again, why not?
5. And if it LOOKS nicer in gloss Black / Gold, why not?

I'm paying less for a chain / sprocket combo with better everything in a 520 conversion, so why not?
Just MY crazy reasons, but I could be wrong. Still a noob learning, that's why I'm here & asking questions.

Thanks!
