Chain & Sprockets
- Honda CBR600RR (2003–2026) — stock front sprocket size = 16T
- Honda CBR1000RR (2004–2026) — stock front sprocket size = 16T
- Honda CBR1000RR-R SP (2021–2026) — stock front sprocket size = 16T
Product Overview
This is a 16-tooth front (countershaft) sprocket from Driven Racing's EVO TECH line, designed for Honda sportbikes. For the CBR600RR and CBR1000RR this is a 520 conversion sprocket — those bikes run 525 or 530 chain stock from the factory and converting to 520 requires a full chain and sprocket setup change.
Key Technology & Design
- Made from case hardened steel for durability at the countershaft position
- Drilled to reduce overall weight compared to a solid sprocket
- 520 chain pitch — conversion from stock 525 or 530 on CBR600RR and CBR1000RR
- Zinc/black finish

Why Convert to 520 From the Stock 525 or 530?
The stock CBR600RR runs a 525 chain. The CBR1000RR ran a 530 chain through 2016 and moved to a 525 from 2017 onward — both are heavier, wider chain pitches designed with longevity and durability as the priority. Converting to a 520 setup reduces the overall weight of the drivetrain by using a narrower, lighter chain and matched sprockets.
The weight reduction is real, but it is worth setting honest expectations. The biggest benefit is felt by riders doing track days or aggressive street riding where rotating mass and drivetrain response are more noticeable. For a rider doing mostly casual street miles, the difference between a well maintained 525 or 530 setup and a 520 conversion is subtle and may not be physically felt at all.
The tradeoff is lifespan. A 520 chain is narrower and lighter than stock, which means it is working with less material. A quality 520 chain maintained properly will last well, but it will generally not outlast a stock 525 or 530 chain under the same conditions. Riders putting high street mileage on their bike should factor that in.
The bottom line — if you are doing track days or aggressive riding and want a lighter, more responsive drivetrain, the 520 conversion is a worthwhile upgrade. If you are primarily a street commuter or touring rider, the stock chain pitch is the more practical choice for long term cost and durability.
Gearing — Staying Stock or Making a Change
This sprocket is 16 teeth, which matches the stock front sprocket size on all bikes in this fitment. Running this sprocket with a stock size rear sprocket keeps your gearing identical to OEM — the only change on the CBR600RR and CBR1000RR is the chain pitch conversion itself.
If you want to use the conversion as an opportunity to adjust your gearing, here is what tooth count changes actually do in practical terms:
Going one tooth smaller on the front (15T) shortens your gearing — the bike accelerates harder through each gear, the engine revs higher at any given speed, and top speed is reduced. The effect is similar to adding approximately two to three teeth to the rear sprocket. Most riders who make this change do it for more pull out of corners or a more aggressive street feel. It is a noticeable change.
Going one tooth larger on the front (17T) lengthens your gearing — the bike revs lower at cruising speeds, feels more relaxed on the highway, and acceleration from a stop is slightly softer. Riders who do a lot of highway miles sometimes prefer this for the lower cruise RPM.
Neither change is right or wrong — it depends entirely on how and where you ride. Stock gearing is well matched for most street use on these bikes.
