Escapamento RD135/125 and RD135z – Product Overview
The Dogster Escapamentos exhaust for the RD lineup is hand-built to order in stainless steel, featuring an exclusive curved design. The SKU covers the full RD135/125 and RD135z range, with a starting price of R$1,690.00.
Every unit ships with:
- Nozzle with flange and springs for a proper, leak-free seal
- Two-hole bracket for secure chassis mounting
- Fully handcrafted finish — no mass production
One important note: product photos on the store may show either the RD135 or the RD135z at random. Always confirm your exact model before completing the purchase to ensure the correct unit ships to you.
Stainless steel is the right material choice here. Compared to carbon steel exhausts, inox holds up far better against corrosion — especially on bikes ridden in rain or high-humidity regions.
Performance and Benefits of a Sports Exhaust for RD
Two-stroke engines like those in the RD family are exceptionally sensitive to the exhaust system. Gas flow directly influences power, torque, and throttle response across the rev range.
A sports exhaust designed specifically for the RD125, RD135, and RD135z delivers:
- Power increases through improved gas evacuation
- Sharper throttle response at mid and high RPM
- Fuller exhaust note, characteristic of 2-stroke motors
- Custom design that stands apart from the stock look
For daily riders and classic bike event participants alike, the upgrade improves both riding feel and visual appeal. The difference in acceleration becomes obvious from the very first gear pull.
Materials and Manufacturing
Handcrafted production defines much of what makes RD exhausts in this segment distinctive. Each piece is built individually, meaning no two units come out identical — particularly in the blue-tinted versions.
The blue coloring results from the heat treatment applied to the stainless steel during fabrication. Shade and tone naturally vary from piece to piece. Product images are illustrative only.
To protect the blue finish, these rules apply without exception:
- Wash only with water and neutral soap
- Never use gasoline, kerosene, diesel, oil, InterCap, Solupam, or any chemical product
- Avoid fuel splashes during refueling
Contact with these substances doesn’t just stain — it can permanently strip the finish and ruin the appearance entirely.
Installation and Maintenance
How to Install the RD Exhaust
Installation involves mounting the exhaust to the bike’s chassis using the included two-hole bracket. The flanged nozzle with springs ensures a correct, secure fit at the engine outlet.
The process may look straightforward, but the manufacturer’s recommendation is firm: have the installation done by a qualified mechanic. A poor fit causes exhaust gas leaks, excessive vibration, and can lead to engine damage in a short period.
Key checkpoints for the mechanic during installation:
- Correct alignment of the nozzle with the engine flange
- Proper torque on all bracket fasteners
- No gaps or movement between the exhaust and the chassis
Maintenance and Care
Once installed, the exhaust requires minimal upkeep — but what it does require must be done right.
On blue-finish versions, using the wrong cleaning product is the single most common mistake. Intercap or Solupam, for example, will permanently stain the inox in a way that cannot be reversed.
In practice, wiping the exhaust down with a damp cloth after use and keeping fuel away from the surface is enough to preserve the finish for years.
Compatibility and Supported Models
| Model | Engine | Compatibility |
| Yamaha RD125 | 2-stroke | All years |
| Yamaha RD135 | 2-stroke | All years |
| Yamaha RD135z | 2-stroke | All years |
The exhaust covers all production years across all three variants. Before purchasing, confirm the selected model matches your bike — the RD135 and RD135z have structural differences that affect fitment.
If you’re unsure, reaching out directly to the manufacturer via WhatsApp is the fastest way to verify compatibility before ordering.
Top Exhaust Brands and Market References
In the sports exhaust market for motorcycles, certain brands consistently stand above the rest — both in Brazil and internationally.Escapamento RD
Dogster Escapamentos is a national benchmark for 2-stroke and custom motorcycle exhausts. The brand serves bikes from Yamaha, Honda, Suzuki, Kawasaki, KTM, BMW, Ducati, Harley Davidson, Triumph, Royal Enfield, and Husqvarna — and also takes on custom projects outside the standard catalog.
Internationally, Yoshimura (Yoshimura R&D of America) ranks among the most respected exhaust manufacturers in the world. Based in Chino, California, the company brings decades of R&D into every aftermarket exhaust system — for both competition and street use. Their commitment to uncompromising quality standards is what separates Yoshimura from generic aftermarket brands.
Both companies share a core principle: build exhaust systems that deliver real performance gains, not just visual appeal.Escapamento RD
Sports Exhaust Systems – Technology and Innovation
Exhaust technology has advanced significantly in recent years. Systems like the Yoshimura RS-12 Hybrid for the YZ450F combine stainless steel headers and titanium mid-sections with an aluminum muffler — the result of decades of racing development.
Other notable systems in the current market include:
- WR125R — full exhaust system for trail and enduro applications
- YZF-R9 — high-performance configuration for Yamaha’s sport segment
- CB1000 Hornet and CB750 Hornet — systems built for Honda naked bikes
- CFMOTO 675SS — exhaust solution for the growing Chinese sport bike segment
- GSX-R1000 (SERT MOTUL) — endurance racing application at the highest level
On the technical side, repack kits and end cap kits allow riders to restore muffler performance without replacing the entire exhaust assembly. Yoshimura’s muffler guide covers silencer styles, system description keys, and exhaust system care — reference material that proves useful even for owners of classic Brazilian bikes like the RD series.Escapamento RD
Compliance, Regulations, and Competition Use
Race-spec exhausts — classified as RACE SERIES — are built strictly for closed-course competition. Installing one on a street-registered motorcycle in the United States violates the Clean Air Act under sections 203(a)(3)(A) and 203(a)(3)(B), with civil penalties reaching up to $37,000 from the EPA. The California Air Resources Board enforces additional state-level restrictions.Escapamento RD
In Brazil, the regulatory framework differs, but the core principle holds: exhausts that bypass or remove emission control system components are not homologated for public road use.
For sanctioned competition, the data typically required includes:
- Competition type: Road, Offroad, Track Day, Exhibition, or Drags
- Racing Organization and Sanctioning Body overseeing the event
- Competition License Number
- Make, Model, and Year of the motorcycle
Understanding these rules prevents both technical disqualification at the track and legal issues on the road.
