What Is Escapamento RD?
Escapamento RD refers to the exhaust system designed for Yamaha RD motorcycles, especially iconic models like the Yamaha RD 135, RD 125, and RD 350. In countries like Brazil and across Latin America, this term is extremely popular due to the cult status of these lightweight two-stroke bikes.
The Yamaha RD series is famous for its speed, simplicity, and unmistakable engine sound. Because two-stroke engines rely heavily on exhaust design for performance, upgrading the escapamento RD is one of the most common and impactful modifications riders make.
In 2026, the demand for aftermarket RD exhaust systems remains strong, driven by enthusiasts who want better performance, sound (“ronco”), and style.
Types of Escapamento RD Available
Stock and Street Exhausts
The original (stock) exhaust is designed for balanced performance and lower noise levels. It’s ideal for riders who want a factory look and compliance with local regulations.
Brands like Pro Tork and original Yamaha parts are common choices for those seeking a quiet to moderate sound suitable for daily use.
Performance and Racing Exhausts
Performance-focused options include:
- Média Baixa (low-mounted exhausts) – Provide a deep, aggressive sound
- Média Alta / Por Cima (high-mounted) – Louder and more race-oriented design
- Dimensionado / esportivo (expansion chamber) – Built for maximum performance and speed
These exhausts are specifically tuned to enhance the powerband of two-stroke engines, improving acceleration and top speed.
Why Escapamento RD Is So Popular
Performance Gains in Two-Stroke Engines
Unlike four-stroke bikes, two-stroke engines depend heavily on exhaust tuning. A well-designed escapamento can significantly improve:
- Mid-range acceleration
- Top-end speed
- Overall engine efficiency
This is why many RD owners upgrade from stock to performance exhaust systems.
The Iconic 2-Stroke Sound
Another major reason riders invest in escapamento RD upgrades is the sound. The Yamaha RD is known for its high-pitched “scream” or aggressive “ronco”, which becomes even more pronounced with aftermarket exhausts.
For many enthusiasts, the sound alone is worth the upgrade—it’s part of the identity of the bike.
Top Escapamento RD Brands in 2026

Choosing the Right Escapamento RD
Street vs Performance Use
When selecting an exhaust, it’s important to consider how you use your bike:
- For daily commuting, a moderate, street-legal exhaust is ideal
- For racing or performance builds, a dimensionado (expansion chamber) offers the best results
Material and Build Quality
Many riders prefer inox (stainless steel) exhausts because they:
- Resist rust and corrosion
- Offer a premium look
- Last longer in harsh conditions
Custom-built exhausts are also becoming more popular in 2026 for riders seeking unique designs and optimized performance.
Legal and Practical Considerations
Noise Regulations
In many cities—especially in Brazil—very loud exhausts can result in fines (multas) for noise pollution. High-performance systems often exceed legal sound limits, so it’s important to check local regulations before installing one.
Proper Tuning Is Essential
Installing a new escapamento without proper tuning can reduce performance instead of improving it. For best results, riders should combine:
- A quality exhaust system
- Proper carburetor tuning
- A well-matched expansion chamber
This combination ensures the engine runs efficiently and delivers the expected performance gains.
Final Thoughts on Escapamento RD
In 2026, escapamento RD upgrades remain one of the most popular modifications for Yamaha RD motorcycles. Whether you’re chasing better performance, a louder sound, or a custom look, the right exhaust can completely transform the riding experience.
The Yamaha RD 135 and its variants continue to hold a legendary status, and the exhaust system plays a huge role in that reputation. With the right setup, riders can unlock the full potential of these iconic two-stroke machines—both in performance and in that unmistakable two-stroke roar.
