Carbonin Carbon Airbox Cover Yamaha YZF-R6 RJ27 (2017-2026) CY18425

Built to the exacting standards of professional circuit racing, the Carbonin CY18425 carbon airbox cover is engineered specifically for the Yamaha YZF-R6 RJ27 across the full 2017-2026 model range. Every panel Carbonin produces is manufactured to meet the rigorous safety and quality demands of motorsport homologation, giving you the confidence to push your R6 to its limits on track without compromise.

Key Features

• Race-grade carbon construction delivers an exceptional strength-to-weight ratio, reducing rotating and static mass without sacrificing structural integrity.
• Purpose-designed airflow geometry optimises the air supply path to the engine, supporting improved throttle response and peak power output.
• Protects the airbox and tank area from ingress of dirt, moisture and debris — critical in both track and wet-weather road conditions.
• Precision fitment engineered exclusively for the YZF-R6 RJ27 (2017-2026): no modifications required, drops straight onto OEM mounting points.
• Motorsport-grade manufacturing standards ensure the panel retains its shape and finish under sustained high-speed and high-temperature conditions.
• Aggressive woven carbon aesthetic complements the R6's race-replica styling and saves weight over the original plastic cover.

Construction & Quality

Carbonin is a specialist Italian manufacturer whose panels are a familiar sight in Supersport and Superbike paddocks worldwide. The CY18425 is produced using high-quality carbon fibre layup techniques that prioritise both surface finish and long-term durability. The result is a cover that resists flex, UV degradation and the thermal stresses generated in a hard track session — qualities you simply cannot replicate with a standard OEM plastic part.

Performance on Road and Track

The airbox cover plays a direct role in managing the air column feeding the YZF-R6's fuel-injected inline-four. By maintaining a clean, undisturbed airflow path and keeping contamination out of the airbox, this Carbonin piece supports consistent engine breathing across all riding conditions. Riders who regularly attend track days will appreciate the weight saving as part of a broader programme of carbon component upgrades, while road riders benefit from the added protection and the uncompromising visual upgrade over the factory cover.
