Ever ask yourself why some smoke emitting yamaha RD’s sound like full-on lightning, while others putter along sounding all timid? The key is down on the frame, in a painstakingly designed titanium-and-NBR rubber doodad known as the escapamento RD. Not just any pipe but a specially designed performance silencer for Yamaha’s venerable RD series two-stroke developed over the years on the racetrack and back roads. Whether your ride an RD 125 or 135, or the world famous RD 350 you can bring more power to the street by knowing something about what makes up your exhaust system and why it helps you turn heads every time.
What is Escapamento RD?
The name “escapamento RD” follows a pattern that joins an English word with the same or an altered version of it in Portuguese, as used in Brazil) with the letters RD (which stands for Yamaha s notorious race-bred motorcycle series). This expanded chamber is in sharp contrast to the typical tubular style of conventional exhausts.
This finely-tuned exhaust system does more than just evacuate burned gases. It does this with precision-engineered pressure waves that push unburned fuel back into the combustion chamber at just the right time. This bloody physics gnaws your back all together lacks a mechanical compressor A crack as the two experiments boosting Hung star.
The result? More power, crisper acceleration and that signature high-pitched howl that marked RDs as the bike of choice back in the 1970s and ’80s.
Benefits That Matter Most to Riders
By installing the perfect escapamento RD, it alters how your bike rides in a number of quantifiable ways. First, You will see substantial power increases – anywhere from 10-20% more horsepower when using a proper tune. Your bike will accelerate quicker, with improved bottom end throttle response.
Second, throttle response becomes razor-sharp. The improved gas flow delivers more pull from the bottom up while making the bike easier to ride. You’ll feel the difference when you’re passing or climbing a hill.
Third, there’s the sound. The RD escapamento is an unforgettable sound — high-pitched, fierce-sounding that let’s everyone now you’re there without sounding obnoxious. It’s mechanical music that fans say is surprisingly addictive.
So too, getting the exhaust “just right” might make some cases fuel with a bit less tarry things in it: all the energy seems to be there.. taxes (couldn’t get that accent) and other similar compaints about having a bit of black stuff left over from burning crushed dinosaurs. Your engine is like, smarter — not dumber.
How to Select Your Perfect Exhaust System
Choosing the perfect escapamento RD depends on your style of driving and what you hope to achieve with it. Stock or OEM systems keep your bike within factory specifications—ideal if you want a stock sounding exhaust and still enjoy the performance gains over your stock system.
Performance aftermarket choices like Pro Tork, Roncar and Coyote have increasing power delivery. With it’s optimized shape to enhance version for low and mid range power while improving durability on pipe high grade Stainless steel this pipes is made strong!
For riders who cannot go fast enough, custom exhaust systems are also available. Expert engine builders may optimize expansion chambers precisely according to the engine’s displacement, porting and intended operating range.
Consider your bike model carefully. The RD 135 has a different exhaust port timing requirement to the RD 350. The shorter (expansion) chambers are just the ticket for pounding around all day in an urban environment (better mid range power and response so you aren’t constantly rowing the gearbox to stay ahead of traffic), or following someone on the highway.
Real-World Applications and Use Cases
The RD escape comes to the fore in multiple ride situations. For those with a daily commute, they’ll love having that extra low-end power when they need to man-handle their way through traffic, but will also appreciate the good fuel economy. Urban riders have told us that new exhausts remove the burden of city riding and make stoplight to stoplight acceleration much more fun.
Curvy backroad squids on weekend lawbreakers appreciate the punch delivered when they crank it over. And the sharpened throttle response will make you trust you can peg it out of corners.
When restoring your bike, you don’t want to use an aftermarket piece that is not period correct that depreciates the value of your vintage motorcycle. Original Works expansion chambers are a hot commodity with collectors that like to keep their RD…period correct.
Something that track days riders and racers love to do as it allows them to squeeze every ounce of power out of their 2 stroke engine through custom exhaust systems matched with tuning tweaks.
Why Escapamento RD Stands Out
What is so special about rd escape 1 systems other than plain old bike exhaust? It’s the engineering that is built for purpose, when it comes to two-stroke engines. Four-stroke machines can run with only a silencer for the exhaust (though there is often some internal baffling) and two-strokes need precisely tuned expansion chambers to perform best.
It produces very usable power, has excellent torque and the expansion chamber generates well-timed pressure waves for enhanced performance. This is not marketing fluff, but rather applied physics that results in gains you can feel while riding.
There’s also a bit of cultural weight to the escapamento RD. This may not be very Bimota, but to Brazilians and lusophone bikers worldwide these two-stroking exhausts mean one thing: freedom as well as a performance inheritance built during the golden years of two-strokes in all racing. An owner is plugged into decades of motorcycling history.
Frequently Asked Questions
How much can I add hp with an escapamento RD?
Quality performance exhausts commonly add 10-20% power, and even more with some models being able to benefit from carburetor jetting by air filter. Actual gains will vary depending on the specific bike model and overall engine condition.
Does an escapamento RD invalidate the bike’s guarantee?
Aftermarket changes generally void warranty anyway, though classics RD’s are of course out of warranty. Be sure to consult your dealer before attempting mods or works on newer bikes under warranty.
Do I have to do some special tuning after my power bank is installed?
Yes, you will probably have to re-jet your carburetor tuning the air-fuel mixture to achieve better exhaust scavenging. In essence without changing the performance characteristics of our car we should be getting no extra power and worst of all would be risking damage to our engine.
Is escapamento RD systems street legal?
Legality varies by location. Some areas have very strict noise and emissions laws. Look up your local laws and find systems with noise dampening in case you need them . Most decent manufacturer’s have E-marked (legal in most countries around the world) versions available.
Escapamento rd tem q limpar com que frequencia?
Exhaust Chambers Carbon buildup in exhaust chambers is one of your two-stroke engine’s worst enemies. Heat and burn your system clean every 5000-7000 kilometers and use chemically imbalanced fuel to avoid damage or restrictions.
Can I fix escapeamento RD to my bike on my own?
Basic mechanical skills and hand tools are all you need to do the job, but professional installation is recommended for proper alignment without leaks and includes tuning updates. If you are unsure, have a professional mechanic do it right.
There are chrome and stainless steel versions, but what is the difference?
Stainless steel is very durable, and does not rust due to being made of stainless steel, ideal for humid environments. Chrome-coated systems offer a traditional look but are susceptible to heat discoloration. Pick based on what’s most important to you in terms of looks vs. durability.
Conclusion
The RD Escapamento is more than tubing hanging under your Yamaha motorcycle; it’s how you release the power, define the sound and increase riding pleasure. By learning how these expansion chamber systems operate, and selecting the correct one for your application, you turn your RD from a nice bike to an unforgettable machine.
