Unleash the full potential of your Benelli BN 125 (2019-2023) with the definitive transmission upgrade from SUPERSPROX. This complete, engineered transmission kit is designed to deliver a significant improvement in performance, durability, and ride quality, transforming your daily commute or weekend adventure. Move beyond standard replacement parts and invest in a perfectly synchronized system that enhances every aspect of your motorcycle´s power delivery.
The heart of this premium kit lies in SUPERSPROX´s world-renowned engineering. Unlike generic sets, every component in this package is meticulously designed to work in perfect harmony. The rear chainring is a masterpiece of innovation, engineered to offer an unrivaled lifespan. By utilizing advanced materials and manufacturing techniques, it provides the extreme durability of high-quality steel where it matters most—on the teeth—drastically extending the life of your drivetrain and saving you money in the long run. This robust construction is paired with a lightweight core, which significantly reduces unsprung weight and rotational mass. This reduction translates directly into tangible performance gains: quicker acceleration, more agile handling, and improved suspension response, allowing your Benelli to feel more nimble and responsive than ever before.
Complementing the advanced rear chainring is the SUPERSPROX front sprocket. Precision-machined from high-grade, case-hardened steel, it is built to withstand the intense torque and stress from the engine. Its design ensures a perfect, secure fit on the output shaft, preventing premature wear and guaranteeing efficient power transfer from the very start of the drivetrain.
This kit includes a high-quality, lightweight chain specifically chosen to match the sprockets. The 428 pitch chain is designed for minimal frictional loss, ensuring that maximum power from your BN 125´s engine is transmitted directly to the rear wheel. This complete, matched system eliminates the guesswork and compatibility issues that can arise from sourcing individual parts. The result is a smoother, quieter, and more efficient ride, with the peace of mind that comes from installing a system where every part is optimized to work with the others. Upgrade your Benelli BN 125 with the SUPERSPROX transmission kit and experience a new standard of reliability and performance.
