Motorcycle enthusiasts know that the exhaust system is more than just a pipe—it’s the heartbeat of a bike. When it comes to Yamaha’s legendary RD series, the escapamento RD has become an iconic component, celebrated for its ability to enhance power, deliver a distinctive 2-stroke roar, and provide endless customization possibilities.
This article dives deep into the world of escapamentos for Yamaha RD motorcycles, exploring history, types, benefits, and expert recommendations.
History of Escapamento RD
The Yamaha RD series first gained popularity in the 1970s and 1980s, with models like the RD 125, RD 135, and RD 350 earning a reputation as agile two-stroke machines.
The escapamento RD played a critical role in defining their performance and sound. Unlike four-stroke exhausts, the expansion chamber design of RD exhausts created a unique resonance, allowing bikes to generate impressive torque and horsepower relative to their size.
During the late 1980s, RD motorcycles became synonymous with street performance. Riders often modified their escapamentos to extract extra power for track racing or street dominance.
Today, the escapamento RD remains a symbol of motorcycle nostalgia, bringing back memories of when Yamaha ruled the two-stroke era.
Why Enthusiasts Choose Escapamento RD
The passion for RD motorcycles is deeply tied to their exhaust systems. Riders choose escapamento RD for reasons beyond performance—it’s a lifestyle statement.
- Delivers the iconic “ronco 2 tempos” sound loved by classic motorcycle fans
- Enhances torque and horsepower for spirited riding
- Offers both retro authenticity and modern tuning flexibility
- Essential for collectors preserving Yamaha RD legacy
For many, installing the right escapamento RD is not just about mechanics but about reliving the golden age of motorcycling.

Types of Escapamento RD Available
Escapamento RD comes in a variety of configurations tailored to different rider needs. Original factory exhausts remain popular among collectors who want to preserve authenticity.
On the other hand, sports exhausts and expansion chambers are sought by performance riders aiming to unlock maximum potential. Dimensioned exhausts, often hand-crafted, are available for those who want fine-tuned results.
These specialized systems take into account engine modifications, displacement, and riding style, making each escapamento RD unique to its owner. The market also offers affordable replicas and parallel versions, giving every rider an option that fits their budget.
Performance Benefits of Escapamento RD
Upgrading to a high-quality escapamento RD provides tangible performance improvements. Two-stroke engines rely heavily on exhaust tuning for efficiency, meaning that the right exhaust can significantly alter power delivery.
Riders often report sharper throttle response, better mid-range torque, and increased top-end speed with optimized systems.
Historically, Yamaha RD 350 riders who replaced stock exhausts with expansion chambers experienced horsepower gains of up to 15%. These modifications transformed their motorcycles from daily rides into race-ready machines. Even today, enthusiasts chase that extra thrill by fine-tuning their exhaust systems.
Sound and Acoustic Engineering in Escapamento RD
One of the most defining characteristics of RD motorcycles is their sound. The escapamento RD produces a crisp, high-pitched resonance that immediately identifies it as a two-stroke engine. This acoustic profile is not accidental—it is the result of careful engineering in exhaust shape, length, and diameter.
The expansion chamber creates a back-pressure wave that amplifies performance while delivering that unmistakable “ronco esportivo.” For collectors and enthusiasts alike, the sound is as valuable as horsepower, cementing escapamento RD as a central piece of motorcycle culture.
Customization Options for Escapamento RD
Escapamento RD allows endless customization, letting riders express both style and performance preferences.
- Chromed finishes for a vintage look
- Matte black coatings for a modern aesthetic
- Tailored pipe bends to improve aerodynamics
- Engraved tips and custom logos
Workshops worldwide specialize in building personalized exhausts for Yamaha RD models. Whether it’s a daily rider seeking practicality or a show bike designed for exhibitions, customization ensures each RD is unique.
Maintenance and Care of Escapamento RD
Like any motorcycle component, the escapamento RD requires care to maintain performance. Carbon build-up is common in two-stroke engines, meaning regular cleaning is essential. Riders should periodically de-coke their exhausts to avoid clogging and power loss.
Rust is another challenge, especially for older models. Applying protective coatings and storing the motorcycle properly can extend exhaust life. Enthusiasts restoring classic RDs often seek original parts, but high-quality reproductions are available to keep their bikes running smoothly.
Popular Yamaha RD Models with Escapamento Upgrades
The Yamaha RD 125, RD 135, and RD 350 stand out as the most iconic models featuring escapamento RD modifications. The RD 350 LC, in particular, became legendary for its racing pedigree and is still a favorite for exhaust upgrades.
In Brazil and Europe, RD motorcycles continue to dominate classic bike meets, with enthusiasts proudly showing off their custom exhausts. The popularity of these models ensures that the market for escapamento RD remains strong, even decades after production ended.
Market Trends and Pricing of Escapamento RD
The market for escapamento RD is diverse, ranging from affordable aftermarket options to premium hand-crafted systems. Prices vary significantly depending on material, craftsmanship, and authenticity.
In 2025, collectors can expect to pay between $200 and $600 for standard aftermarket exhausts, while custom dimensioned systems can exceed $1,000. Original Yamaha exhausts, when available, fetch even higher prices due to rarity and demand among restorers.

In Brazil, several workshops specialize in hand-crafted expansion chambers, while European suppliers focus on authentic replicas. Online forums and motorcycle clubs also serve as key hubs for sourcing rare parts and trusted recommendations.
