HI Guys,

My 2010 F4 has about 7500 miles on it and the service manual says to replace the chain. Does anyone recommend a specific one? Also says to replace the sprockets. Do you suggest getting a performance kit? I've seen a lot of these 520 conversion kits but what's the difference in performance?

In the real, regular world...none.

Stick to standard for road use if you can. If that chain was well looked after, it will go a lot further, but that's not my call. Replace the lot with OEM, look after it, and you'll be fine for 15k I recon.

Alright Chuck - I've just got back from the lab, having tested your hypothesis that "In the real world these is no difference between a 525 and a 520 chain set".

My findings are that, having ridden for 15,000 kilometers overnight in the lab at work with both the 520 & 525 chain set, indeed there is a measurable significant difference.
And that difference is that, in the tested environment (linoleum floor with fluorescent lighting), the 520 chain looks prettier!

Now I'm off to bed.

Shouldn't you be mowing the lawn for Ed, Dave?
I see, from the picture, that you did put on pants...unnecessary, but a nice gesture!
(BTW, don't look down...one of your legs is missing!)

Thanks for the "Heads up" about the "missing leg" (good pun that).
I have contacted the lost & found department.
They said that they have 2 right legs and a pancreas but no left leg has been "Handed in" - I'm on fire here!

Thanks for the helpful and entertaining comments!

asofi, the 525 bit is the pitch, the length is measured in number of links, check Donsy's manual links in the sticky.

You cannot go wrong buying from any of the site sponsors, not sure where you are located in this little old world but here in the UK I use Design Corse because they are brill and UK based.

Don't be tempted to go cheap on the bay, it could end up costing you more than just money.

Providing the chain has been looked after it shouldn't need replacing at such a low mileage despite what the manual says, 15000 miles would be more like it.

Not wanting to be a smarty pants..but I once bored myself senseless for a whole afternoon reading about chains.

a 525 chain has a pitche centre to centre pins of 5/8 inch .

It has a inside plate to plate dimension of 2.5 ( two and a half ) eighths of an inch.

So on my Jota which is a mighty 630 , the chain is 6/8 inch pitch and 3/8 inside plates width.

Next time you are a ta boring dinner party remember this post lol

ps Dave why are you cordoned off in the work place ?:naughty::naughty:

Does it really need replacing? I have just put my original chain (DID 525ZVM2) back on after ~18,000 miles and it is still perfect. Both of the sprokets looked brand new after cleaning the oil off.
If you have to change it stick with DID, that's what it came out of the factory with.

the life of a chain and sprockets will be determined by how well it is maintained and NOT the mileage. A poorly maintained chain /sprockets may be totally cactus at 2000 kms but a well maintained chain (Scott oiler comes to mind) could easily be good at 25,000 kms. The best thing is check the chain for wear (tight/loose as it is rotated) and if it is worn replace chain and sprockets.

Got it, thanks for the advise. I was going to replace the chain just based off of the service manual but I am going to check the chain before making any investment.

Not meaning to nitpick Joe, and imperial is not my native language, but wouldn't 2.5 eighths of an inch roughly equate to 5/16ths?:stickpoke

changing parts?

asofi;
the manual tells you to replace many things at silly mileages;

chains......my Aprilia RSVR went 30,000mi before needing a chain the Brutale is coming up on 24,000mi and the chain shows no signs of wear

spark plugs......cars go 80,000mi on a set of the same plugs as MVs

front wheel bearings.......at 22,500mi :wtf::wtf::wtf: I have 327,000mi on the ones in my El Camino......ane trust me they were harder miles than on an MV

and the best one, rear hubs.....at 22,500mi?????
how about replacing the $34 bearing when needed, instead of the hub MV no longer supplies?

fucktards
