The ignition curve of the SXS digital box is specially adapted to the series cylinder head and the use of at least 98 octane fuel.

The advantages:

• Higher peak power and speed
• More torque in the medium speed range
• Improved response
• The best possible performance

We recommend use in combination, with the Doma factory exhaust system and the SXS spark plug for maximum use of performance

Using the SXS digital box on the 125 EXC is only of benefit in conjunction with a factory exhaust system.
