Sitta Front Sprocket Triumph Daytona 675 / 675 R (2006–2017) Z001 – 14 to 18 Teeth, 520/525 Pitch

Machined from high-strength chromium-molybdenum steel, the Sitta Z001 front sprocket is built to a standard that the Triumph Daytona 675 and 675 R genuinely deserve. Whether you are dialling in your gearing for a track day at Silverstone or refining the street manners of your inline triple, this sprocket delivers the precise fitment, minimal chain wear and long-term durability that only a quality-first component can offer.

Key Features

• Chromium-molybdenum steel construction provides exceptional tensile strength and resistance to wear under sustained high-RPM loading.
• Precision-machined tooth profile ensures exact chain engagement, eliminating the play and noise associated with lower-grade sprockets.
• Available in 14, 15, 16, 17 and 18 teeth across 520 and 525 chain pitches, giving you genuine flexibility to tune your gearing ratio.
• Shorter gearing (14–15 teeth) sharpens acceleration and engine response — ideal for tight circuits and urban riding.
• Taller gearing (16–18 teeth) reduces cruising RPM and raises top speed — suited to motorway commutes and fast open-road riding.
• Drop-in fitment for all Triumph Daytona 675 and 675 R models from 2006 through 2017 — no modifications required.

Material Quality and Construction

The Z001 is manufactured from chromium-molybdenum steel — an alloy chosen specifically for its high fatigue strength and surface hardness. Under the repeated shock loading of a sports motorcycle drivetrain, inferior sprocket materials stretch and deform, accelerating chain wear and degrading power delivery. Sitta's choice of material and heat treatment process resists exactly that, keeping the tooth geometry consistent mile after mile. The result is a sprocket that protects your chain investment as much as it improves your gearing.

Gearing and Performance

The Daytona 675's inline three-cylinder engine is highly sensitive to gearing changes — even a single tooth difference produces a noticeable shift in character. Fitting a 14 or 15-tooth Z001 sharpens the initial drive, making the motor feel more aggressive out of slow corners and through city traffic. Moving to a 17 or 18-tooth sprocket extends the gearing, letting the engine sit lower in its rev range at motorway speeds and lifting the theoretical top speed. With nine size-and-pitch combinations available under the Z001 part number, you can find the exact ratio that suits your riding — and change it again as your needs evolve.

Fitment and Compatibility

The Sitta Z001 front sprocket is confirmed to fit the following Triumph models:

• Triumph Daytona 675 — model years 2006 to 2017
• Triumph Daytona 675 R — model years 2006 to 2017
• Compatible chain pitches: 520 and 525

Always verify your chain pitch before ordering. If you are converting to a 520 chain for weight saving, select the 520-pitch variant of the Z001 to match.
