Renthal 16-Tooth 520 Front Sprocket 
Product Overview
This is a Renthal 16-tooth 520-pitch front sprocket covering a range of Suzuki and Kawasaki sportbikes and nakeds. Every bike in this fitment list runs 525-pitch chain from the factory — this is a 525-->520 conversion sprocket across the board. Installing it requires replacing the chain and rear sprocket with 520-compatible components on every model listed.
Key Technology & Design
Renthal makes this sprocket from nickel-chrome-molybdenum alloy steel, CNC-machined rather than stamped for tighter dimensional tolerances and more consistent tooth geometry. The design includes radial lightening holes to reduce rotating mass. Natural finish.

Why Convert to 520
Every bike in this fitment list leaves the factory with 525-pitch chain — chosen by the manufacturer for durability and longevity under street use. A 520 conversion replaces the chain and both sprockets with narrower, lighter components.
The real benefit is reduced rotating mass. A lighter chain and sprocket assembly means less weight spinning at the rear wheel. This is most noticeable for track riders and aggressive street riders — the bike responds more quickly to throttle inputs and feels lighter overall. For casual street commuters the difference is subtle and may not be physically felt.
The tradeoff is longevity. A 520 chain is working with less material than a 525 and will generally not outlast a stock-pitch setup under the same conditions. Riders who prioritize maximum chain life over rotating mass reduction are better served staying with the stock chain pitch.
The bottom line: 520 conversion is a meaningful upgrade for track use and performance-focused street riding. For everyday commuting and general street miles, the stock chain pitch is the more practical choice.

Why Convert to 520

Every bike in this fitment list leaves the factory with 525-pitch chain — chosen by the manufacturer for durability and longevity under street use. A 520 conversion replaces the chain and both sprockets with narrower, lighter components.

The real benefit is reduced rotating mass. A lighter chain and sprocket assembly means less weight spinning at the rear wheel. This is most noticeable for track riders and aggressive street riders — the bike responds more quickly to throttle inputs and feels lighter overall. For casual street commuters the difference is subtle and may not be physically felt.

The tradeoff is longevity. A 520 chain is working with less material than a 525 and will generally not outlast a stock-pitch setup under the same conditions. Riders who prioritize maximum chain life over rotating mass reduction are better served staying with the stock chain pitch.

The bottom line: 520 conversion is a meaningful upgrade for track use and performance-focused street riding. For everyday commuting and general street miles, the stock chain pitch is the more practical choice.
