Summary: Why the "naked" body ?
The exhaust pot is the "lung" of your 2-stroke engine. It works by resonance: the precise shape of the body returns the pressure waves in the cylinder to improve the filling.
In version "naked", You buy only the metal body (the "belly" of the exhaust). It's the ideal choice if:
-
Your current body is bumpy or cracked following a tape.
-
You want to keep your current chicane / cartridge (if it is still in good condition).
-
You prefer to go back your internal elements yourself to customize your maintenance.
- Why choose the original body Rotax ? ?
-
Resonance approved: The odds of the pot Rotax are calculated at a millimeter. An "adaptable" or malformed pot will never give the same power curve. With the origin, you are sure that your engine develops the performance provided by the plant.
-
Quality of materials: The thickness of the sheet is crucial. Too thin, it vibrates and cracks; Too thick, it is too heavy and dissipates the heat badly. Rotax mastery the perfect balance.
-
Vibration resistance: The welds Rotax are designed to cash the high frequency vibrations of the 125cc without breaking.
💡 Michel's trick
"Never underestimate the impact of a bump on the pot. On a Rotax Max, a bumpy exhaust modifies the return wave and makes you lose easy 0.5 to 1 horse or more in the mid-diets. The trick: Always inspect the lower part of the body after a track output. If you have a depression, do not look to straighten it with the torch, it weakens the metal and changes the resonance. My Pro Council: When you mount this naked pot, use new springs. A relaxed spring makes the pot vibrate, which ends up creating cracks on the fastening legs in no time! "
