Interchangeable Domes 

For 2018-2026 KTM / Husqvarna / GASGAS have redesigned the motor on the 85cc bikes. Also have option for 105’s all the way up to the 112cc Super Mini’s. (See Dropdown to select size.) The new power plant now comes with an interchangeable cylinder head dome and separate cylinder head. Nihilo Concepts has developed two versions of domes that will change the power delivery of you 85. These new 6061 Billet aluminum domes will fit right into your stock cooling jacket or into the new Nihilo “Extra Capacity Cooling Head” sold separately.

• “Top End Outdoor MX Dome” engineered to deliver more over rev and top end power for those long outdoor tracks where you are on the top end of the power band most of the time.
• “Mid / Low SX Dome” designed to provide better mid to bottom end power when you have to get out of the corner faster. The motor will still rev on top but you will notice the difference on the bottom.

Combine these domes with our new “Extra Capacity Cooling Head” for the ultimate bolt on performance mod. (sold separately)  

***It is recommended to use a minimum of 100-octane fuel.

This will work on the 2025 but the 14mm spark plug must be used!!!
