520 Conversion Kit with Aluminum Rear Sprocket and DID ERV3 Gold Chain
Complete fitment list at bottom of this page.
All bikes on the fitment list came stock with a 525 pitch chain
Convert your Aprilia to a 520 racing chain size. Reduce rotating mass for quicker acceleration and less drag on deceleration.
Kit includes:
- 15-17 tooth STEEL front sprocket,
- 40-45 tooth hard anodized ALUMINUM rear sprocket
- DID 520 ERV3 chain with rivet connecting link
This kit is perfect for racers. The o-ring chain is 120 links long so several different sprocket ratios can be accommodated (though 15/43 is by far the most popular overall ratio across all bikes and model years)
Front Sprockets will be AFAM. Rear Sprockets will be Esjot of Germany from 7075 aluminum.
**Please note: Installation of this chain requires a Rivet Installation Tool.
*Please Note: If you have never bought aftermarket wheels, you do not have Marchesini/BST/Piegas.
