Escapamento RD: Simple Guide to Yamaha RD Exhaust (Sound, Performance, and Buying Tips)

ByAdmin

The Yamaha RD motorcycles (RD 125, RD 135, RD 350) are very popular with two-stroke bike lovers. These bikes are light, fast, and have a special sound that many riders love. One part changes the bike a lot: the escapamento RD (the exhaust system).

On a two-stroke engine, the exhaust is not only for taking out smoke and gas. It also helps the engine make power. This means that changing the exhaust can change:

  • How fast the bike feels

  • How strong the engine pulls

  • How the bike sounds

  • How much fuel the bike uses

This simple guide will help you understand what an escapamento RD is, how it works, and how to choose the right one.

1. What Is Escapamento RD?

Escapamento RD means the exhaust made for Yamaha RD bikes. There are different kinds of exhausts:

  • Original factory exhaust (OEM)

  • Custom or handmade exhaust

Main jobs of the exhaust:

  • Take hot gas away from the engine

  • Help the engine breathe better

  • Change the sound of the bike

  • Help control engine power

2. How the Exhaust Works on a Two-Stroke RD

Two-stroke engines work in a special way. The exhaust shape helps push fresh fuel and air back into the engine before the exhaust port closes. This helps the engine make more power.

What a good exhaust can do:

  • Make the bike faster

  • Improve throttle response

  • Help the engine run smoother

  • Change where the engine makes power (low speed or high speed)

Power difference by exhaust type:

Exhaust Type Low Speed Power Middle Speed Power High Speed Power
Original (OEM) Good Medium Low
Street Performance Medium Good Medium
Racing Exhaust Low Medium High
