Handcrafted high-performance motorcycle exhausts: racing design, sporty sound, and Made in Italy quality to push beyond every limit.
Enhance the performance of your Yamaha YZ 125 to the maximum level with the handcrafted DBR expansion. Not just an industrial component, but a piece of mechanical engineering designed to optimize the resonance of Iwata's 2-stroke engine.
The Secret of Sound and Power
The heart of DBR performance lies in the choice of materials: we use exclusively high-quality P04 sheet metal. Unlike common steel, P04 sheet metal offers superior resonance capacity, ensuring that essential "wave return" to efficiently empty and fill the cylinder.
Each expansion is hand-hammered and precisely welded to guarantee perfect internal volumes. The visible welds and artisanal finish give your bike a DBR Factory look, identical to competition motorcycles.
Choose Your Finish: Maintenance or Total Protection
We offer two options for managing your P04 iron expansion:
- Racing Finish (Oil): For purists. The exhaust is supplied raw; maintenance involves the classic application of a thin layer of oil after washing to prevent oxidation and keep the metal "alive".
- Transparent Cerakote™ Treatment: The ultimate rustproof solution. A high-temperature ceramic coating that seals the P04 sheet metal, protecting it from mud and moisture without hiding the spectacular welds and the natural color of the metal.
Technical Advantages and Compatibility:
- Delivery: Increased mid-range thrust and higher top-end, ideal for modern tracks.
- Lightweight: The density and thickness of P04 sheet metal allow reducing the overall weight compared to the original OEM exhaust.
- Sound: Dry, metallic, and responsive tone, characteristic of high-quality iron.
- Versatility: 100% compatible with the original silencer, DBR silencers, or major aftermarket brands.
Specific Compatibility:
Plug & Play installation on frames:
- Yamaha YZ 125: Models from 2005 to 2021.
⚠️ IMPORTANT MAINTENANCE NOTE:
If you purchased the muffler in the Racing Finish version (without Cerakote treatment), remember that P04 iron is unprotected. To preserve the integrity and appearance of the exhaust, it is essential to dry it after each wash and apply a protective product.
Recommended products for caring for your DBR:
- DBR Care Kit Classic - Anti-Rust Oil + Rust Remover + Sponge & Stickers
- DBR Rust Remover - Anti-Rust Treatment for Mufflers
- DBR Oil - Protective Anti-Rust Spray
Without constant maintenance, surface oxidation is natural and could prematurely damage the product.
