Yamaha YZF-R125 2014-2020

Transform your riding experience with our premium exhaust system specifically engineered for the Yamaha YZF-R125 2014-2020 model range. This high-performance slip-on exhaust system represents the perfect balance between street-legal compliance, enhanced performance, and distinctive sound character that will make your R125 stand out from the crowd.

Designed and manufactured to exacting standards, this complete exhaust kit delivers everything you need for a straightforward installation on your Yamaha YZF-R125. Whether you’re commuting through city traffic or enjoying spirited rides on your favourite country roads, this exhaust system provides noticeable improvements in throttle response, weight reduction, and that unmistakable performance exhaust note that turns heads wherever you go.

Complete Exhaust Kit for Yamaha YZF-R125 2014-2020

This comprehensive exhaust package includes everything required for a professional-grade installation. You’ll receive one MTC exhaust measuring 250mm in length, precision-engineered to deliver optimal exhaust gas flow whilst maintaining excellent ground clearance. The CNC mandrel bent system and link pipe ensure smooth internal surfaces with consistent diameter throughout, maximising exhaust velocity and minimising turbulence for improved engine efficiency.

The kit comprises the following premium components:

• 1 x MTC Exhaust 250mm Long – crafted from high-grade materials for durability and performance
• 1 x CNC Mandrel Bent System & Link Pipe – precision-manufactured for perfect fitment
• 2 x Connecting Clamps – robust stainless steel construction ensures secure connection
• 1 x Stainless Exhaust Strap – corrosion-resistant and built to last
• 1 x Exhaust Strap Rubber – isolates vibration for a rattle-free installation

The mandrel bending process used in manufacturing this exhaust system is crucial for maintaining consistent pipe diameter throughout all bends, unlike crush-bent systems which can create restrictions. This manufacturing excellence translates directly to better performance on your motorcycle, allowing exhaust gases to exit more efficiently and reducing back pressure that can inhibit engine performance.

Performance Benefits for Your Yamaha YZF-R125 2014-2020

Upgrading your exhaust system delivers multiple tangible benefits beyond simply improving the sound of your motorcycle. The reduction in weight compared to the standard factory exhaust system contributes to improved handling characteristics and a slight enhancement in power-to-weight ratio. Every kilogram saved on a 125cc machine makes a noticeable difference to acceleration and manoeuvrability.

The improved exhaust flow characteristics help your engine breathe more efficiently, particularly in the mid to upper rev range where the single-cylinder engine of the YZF-R125 produces its peak power. Riders typically notice crisper throttle response and a more eager feel throughout the rev range. According to Motorcycle News, one of the UK’s most trusted motorcycling publications, exhaust modifications remain among the most popular and effective upgrades for learner-legal sports bikes.

The distinctive exhaust note provided by this system gives your Yamaha YZF-R125 a more purposeful and sporty character whilst remaining considerate for road use. The tone is deeper and more resonant than standard, reflecting the performance heritage of the YZF family without being antisocially loud.

Professional Installation for Yamaha YZF-R125 2014-2020 Models

The slip-on design with link pipe configuration makes installation straightforward for those with basic mechanical aptitude and the appropriate tools. The system connects to your existing headers, meaning you retain the catalytic converter for emissions compliance whilst upgrading the rear section of the exhaust system. The included stainless steel clamps provide secure, leak-free connections that can withstand the thermal cycling and vibration inherent in motorcycle exhaust systems.

The exhaust strap and rubber mounting ensure the system is securely located whilst allowing the necessary thermal expansion and isolating vibration. Proper mounting is essential for longevity and preventing stress fractures, so we recommend following the installation guidance carefully and ensuring all connections are properly tightened to the specified torque settings.

Quality Construction Built to Last

Stainless steel construction throughout the system ensures excellent corrosion resistance, particularly important for riders who use their machines year-round in British weather conditions. The combination of quality materials and precision manufacturing means this exhaust system will maintain its appearance and performance for years to come, representing excellent value for your investment.

If you’re looking to upgrade other Yamaha models in your garage, we also offer systems for larger capacity machines such as the Yamaha YZF 1000 R1 2009 – 2014, as well as alternative configurations for the R125 including our Yamaha YZF-R125 full stainless system and Mini oval exhaust for those seeking a different aesthetic.
