• Cylinder head separate from combustion chamber
• Easy modification of the engine characteristic by changing the combustion chamber insert (e.g., from Motocross to Enduro setting)
• No need to replace the entire cylinder head in case of wear; only the insert needs to be replaced
• The aluminum alloys provide improved heat dissipation and thus improved performance gains

• factory spark plug

IMPORTANT:

The carburetor jetting must be adjusted to the selected combustion chamber insert and your vehicle model year (e.g. selected combustion chamber insert = Motocross type; vehicle = TE 250 model year 14; carburetor jetting to be selected = TC 250 model year 14). The carburetor jettings for models 250 and 300 are identical. When using the ‘EXTREM’ combustion chamber insert, always select the SX carburetor jetting for your vehicle’s model year. More information on the carburetor jetting can be obtained from your authorized dealer.
