Vortex 526KV4-45 VTX Aluminum Rear Sprocket 45T

The Vortex 526KV4-45 is a 45-tooth VTX series aluminum rear sprocket designed as a direct-fit replacement or performance upgrade for compatible motorcycles. Manufactured from high-grade 7075-T6 aluminum alloy, this sprocket delivers an excellent strength-to-weight ratio, reducing unsprung rotary mass for improved throttle response and handling compared to stock steel sprockets.

Vortex sprockets are precision CNC-machined to exacting tolerances and feature hard anodized teeth for exceptional wear resistance and long service life. The 526 chain pitch designation ensures compatibility with standard 525-series drive chains.

Key Features:

• 45 Tooth count — suitable for adjusting final drive gearing for track or street use
• 525 chain pitch compatible — fits standard 525-series drive chains
• 7075-T6 aircraft-grade aluminum construction — lightweight and durable
• Hard anodized finish — resists wear, corrosion, and heat

• Made in the USA — Vortex Racing manufactures domestically to strict quality standards

Whether you're fine-tuning gearing ratios for a specific circuit or replacing a worn sprocket, the Vortex 526KV4-45 is a proven choice for sport bike and racing applications. Always replace the drive chain when installing a new sprocket for optimal performance and longevity.
