Alongside the slip‑on, the package includes a premium rear wheel assembly — featuring a strong rim, precision‑engineered hub, and a durable off‑road tire selected for traction and durability.

Key Features & Specifications
RS‑4 Slip‑On Exhaust Muffler
The heart of the YOSHIMURA KAWASAKI KX250F 17‑20 RS‑4 SLIP‑ON EXHAUST MUFFLER SS‑AL‑CF” Rear Wheel Rim Hub Tire package is the RS‑4 slip‑on muffler. Crafted with stainless steel (SS), aluminum (AL), and carbon fiber (CF) components, this muffler is engineered for:
-
Improved horsepower and torque delivery
-
Enhanced throttle response
-
Race‑ready sound quality
-
Reduced weight compared to stock systems
The RS‑4 design focuses on optimizing backpressure and flow to unlock more usable power across the rev range, especially in mid‑to‑high RPMs.
Premium Rear Wheel Components
Included with the exhaust muffler is a high‑quality rear wheel assembly tailored for motocross use:
-
Rim: Lightweight yet strong, designed for rough terrain
-
Hub: Precision machined for long‑lasting performance
-
Tire: Off‑road tread pattern for traction on dirt, sand, and mud
This combination ensures that the YOSHIMURA KAWASAKI KX250F 17‑20 RS‑4 SLIP‑ON EXHAUST MUFFLER SS‑AL‑CF” Rear Wheel Rim Hub Tire not only improves power delivery but also traction and stability on varying surfaces.
Performance Benefits
Enhanced Power and Response
Installing the slip‑on component of the YOSHIMURA KAWASAKI KX250F 17‑20 RS‑4 SLIP‑ON EXHAUST MUFFLER SS‑AL‑CF” Rear Wheel Rim Hub Tire results in more efficient exhaust flow. Riders report a noticeable increase in throttle response and smoother power curve, which is particularly beneficial on technical tracks.
Weight Reduction
The use of lightweight materials such as stainless steel and carbon fiber in the RS‑4 slip‑on reduces overall weight compared to stock exhaust systems. Less weight means improved acceleration and more agile handling.
Improved Traction and Handling
The included rear wheel elements — rim, hub, and tire — work together to provide increased traction off jumps, better grip in corners, and higher confidence on challenging terrain. Pairing high‑performance wheel components with the exhaust upgrades makes the YOSHIMURA KAWASAKI KX250F 17‑20 RS‑4 SLIP‑ON EXHAUST MUFFLER SS‑AL‑CF” Rear Wheel Rim Hub Tire a well‑rounded performance enhancement for motocross riders.
Installation Notes
Installing the YOSHIMURA KAWASAKI KX250F 17‑20 RS‑4 SLIP‑ON EXHAUST MUFFLER SS‑AL‑CF” Rear Wheel Rim Hub Tire package requires basic mechanical skills and standard tools. The slip‑on exhaust attaches to the stock header, and the rear wheel assembly replaces the OEM rear wheel. Proper torque specifications should be followed, and alignment should be checked after installation.
Comparing with Related Products

The FMF PowerCore 4 slip‑on is a popular alternative.

Pro Circuit T‑6 Slip‑On
