Hi folks,

after some 16.500kms my front sprocket is toast and I'm in business for a new set of sprockets and chain. Surprisingly, I could not find specs on the chain.

The only hint was here in the forum:

I have fitted a new chain and sprockets at 12,700km as I found a couple of "tight links" in the original Regina chain, (I'm not a fan of Regina chains), I fitted new sprockets and a DID ZVMX 520 chain and it has been issue free since fitting. I went up 1 tooth on the front from 15t to 16t to get the speedo reading correctly, it's now within +/-1kmh now, so I'm well chuffed. Front sprocket is a 520 Aprillia Tuono item and the 520 52t aluminium rear sprocket is a Vortex item.

@smithy - would you care to share some more details on what sprockets exactly you have used, like what MY/displacement? If purchased online I'd appreciate a link to be sure I get the right ones. Also, I was wondering if the Experia is really using a 520 chain and not 525 as the Ribelle/SS9 is using - so you are super sure with that? I'd also appreciate the chain length. Again, 120 is mentioned for Ribelle and SS9. Probably need to count...

Thanks for posting any specs!

The Experia is the only one of the Energicas which use the 520 chain & sprockets, all the others are 525. The OEM rear sprocket on the Experia is also aluminium.

The Energicas use the Aprillia front sprocket splines so 90% of the Aprillia sprockets will fit, Tuono, RSV etc..

Rear sprocket I used is a Vortex aluminium 52t which I bought from "Brocks Performance", these also fit a lot of the aftermarket carbon wheels etc...

You'll also need the special front sprocket nut tool.

Perfect writeup - thanks a lot!!

From your link I see it has in ID of 76mm and pitch circle of 100mm. I guess just any 520 sprocket will do that meets that interface and has 52T. I don‘t like that Vortex sprocket too much and would prefer to go with a cleaner look of the original Sitta - just not available in any shop around the corner in 52T. But I will keep on looking.

Try JT Sprockets,  Superlite, AFAM or Supersprox as a source for sprockets, the latter even do made-to-measure jobs with color options. Delivery time can be 3 months, though.
There are front sprockets available which have thick rubber rings on the sides for noise reduction. I tried them but could not find any difference to the common one, so not worth the money in my view.

The front sprocket tool I got from Amazon for less than 20 €. When changing the front sprocket, I recommend to change the star-shaped locking plate as well, it's only 2 €.

As for chains, I do not recommend Regina, especially not the expensive HPE. The claim of 'maintenance free' is an outright lie.
Currently I have a Enuma chain (Japanese manufacturer) with 25.000 km on it and it's still OK. Advantage of this chain is a screw-on connector link, so I didn't need a special chain tool for installation. You get them at Louis or cheaper at Kawa-Schrauber.de.

Im running a 520 on my race bike.  It's a bit lighter but yes the lower powered energica's will take the 520.  If you decide to play around with tooth count, be mindful that if you deviate far it might start messing with your traction control, or potentially ABS.

THis is one thing I wish energica could put in their normal software is a tooth count so it could calibrate it's measuring better.  It's on the race bike, but they probably figure most normal people are not going to be playing with that stuff, so didn't include in regular software.

Arron thanks - that’s a good hint!
In fact, I have chosen a 16T front sprocket. That 7% difference will probably correct the speedo to show the true speed. For the rear I will stay with the original Sitta sprocket - I like the design.
Surprisingly, I was not able to find it anywhere in the net. All Sitta sprockets for the Experia rim I could find end with 48T. No 52T. I had to order it through my dealer from Energica for 70€. Well let‘s see how long this will take.
I got all tools and a DID ZVMX chain, just waiting on the rear sprocket.

Changing sprocket tooth counts has no effect on the ABS or traction control...all the ABS and T/C information is taken from wheel speed not motor rpm...it's only an issue if you dramatically change tyre sizes. The speedo is indeed taken from motor rpm which is why changing the front sprocket to a 16t on the Experia will have the speedo near spot-on.

just as a review.

The Stock front sprocket is 16 teeth
The Stock Rear sprocket is 52 teeth
the Stock Chain is 520 pitch with 120 links.

Is that right?

Stock Experia front sprocket is 15t, not 16t....the rest is correct.

Got it. Thanks

Found some time and changed the chain.

WOW.

What a difference in noise level! Even when the stock chain was new which happens with new bikes , it was not THAT low. And those of you who ever changed a chain might also have noticed a lower noise.
I have the habit of thoroughly cleaning the chain after ca. 800-1.500km, depending on the road conditions and how dirty it looks. I do apply chain lube regularly, so I can say it does not lack any maintenance. I also realized after some 8.000kms that the chain had slight tendencies to become unevenly long - this also has added to the noise recently. Furthermore, also the larger sprocket 16T vs. the stock 15T will add to a low noise. Certainly not too much, but it definitely does.

Well guys, in case you consider a new chain - do it sooner than later! You will hear the difference!

[Specter]

The roads out here trashed my chain real fast.  We have that silt and that shit gets into everything and just tears it up.  I agree with you that you don't notice it because it comes on slow but when you do put a new one on, it's like wow, that made a big difference.

Ordered a custom superprox aluminum 52T rear (they produce 49/50t options with the stock already)
Gambled [ and LOST] on a 16t front from the aprilia 660s since I have one floating around the garage already. If the splines/offsets work out [they don't], that's an easy replacement vs the "special" 520 size sprockets for the RSV4.

If I'd thought the whole exercise through, I'd have gone for a 15t front and one of the 49/50t supersprox for similar gearing change and not paying the custom order price/delay penalty.

Now I get to twiddle my thumbs for a month or two.

Edit: the aprilia 660s (tuareg/tuono/rs) have different spline count and offset. Zero compatibility.

I'm also in the process of ordering a 52 tooth SuperSprox. Aluminum carrier with the steel chain ring. When I get it installed I'll post back and we can compare notes. I also got an aftermarket replacement front in the stock 15 tooth configuration from AF1. SKU AF61601-15.

Staying with the 15t front sprocket will have your Experia still showing 7-8% out on the speedo. Changing to a 16t will have it near perfect.
