The larger outer diameter of the screw head counteracts the effect of soiling in the adjustment screw channel. Furthermore, the screw is longer and easier to access for setting the idle mixture on the carburetor.

DO YOU KNOW about the benefits of a REKLUSE automatic clutch?The centrifugal clutch opens automatically at very low revs, so it’s no longer possible for the engine to stall “unintentionally”. No more shifting is required, although it is still possible.The benefits:

• No stalling of the engine in critical situations such as braking into corners, on descents, mid-jump, when starting or pushing
• The improved traction can be controlled perfectly and smoothly via the throttle twist grip alone
• Slippery, extremely steep sections can therefore be conquered more easily (saving time and ensuring faster lap times)
• More relaxed, fatigue-free and controlled riding, even over longer distances and in tough terrain
• Unrestricted and total concentration on the perfect line

The latest generation of the Rekluse automatic clutch featuring EXP technology.

This automatic clutch is installed into the standard clutch, i.e. simple, uncomplicated and quick installation.

The benefits:

• Easily adjusted from the outside via the clutch slave cylinder, so removal of the clutch cover or dismantling of the clutch is no longer necessary
• No stalling of the engine in critical situations such as braking into corners, on descents, mid-jump, when starting or pushing
• The improved traction can be controlled perfectly and smoothly via the throttle twist grip alone
• Slippery, extremely steep sections can therefore be conquered more easily (saving time and ensuring faster lap times)
• More relaxed, fatigue-free and controlled riding, even over longer distances in tough terrain
• Unrestricted and total concentration on the perfect line
• No more shifting is required, although it is still possible.
• Special hand brake lever kit available, allowing braking of the rear wheel with the left hand.

Ever had to cut short a training session or a race due to a faulty spark plug? This will never happen again with the extremely robust SXS spark plug and its special properties:

• Iridium center electrode tip
• Reinforced earth electrode (against vibration and breakage)
• Special design with improved anti-rusting properties

We recommend use of the SXS spark plug when fitting power-boosting parts, such as SXS cylinder heads, factory exhaust systems or the SXS CDI unit.

Specially designed for use on sandy tracks (high thermal loads!). Volume 14.8ml = less compression (standard: 13.8ml).

Big bore kit with extra displacement (105cm instead of 85 cm). For plenty of torque and even more peak power.

All the parts required for converting your 250 SX to a 300 SX for the MX3 class. No need for the jets to be changed on the 250 SX carburetor.

This complete cylinder consists of specially machined individual parts of minimized tolerances, which guarantees higher performance throughout the entire rpm range.

Combustion chamber insert manufactured from highest grade aluminum, with standard combustion chamber shape.

Combustion chamber insert for SXS cylinder head with the following properties:

• Manufactured from an alloy specially developed for the application.
• Improved engine performance thanks to the excellent thermal conductivity of the material used without changing the combustion chamber.
• Prevents undesirable detonations in the cylinder, which in turn has a positive effect on the service life in use and the engine performance.

The SXS cylinder heads with variable combustion chamber are a must-have for any racer and offer the following properties:

• 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 used provide improved heat dissipation and thus improved performance gains

To boost your motorcycle’s performance even further, we recommend a combination of the factory cylinder heads with the following parts:

• SXS spark plug
• SXS digital box
• factory exhaust system

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 = 250 EXC model year 09; carburetor jetting to be selected = 250 SX model year 09). 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.
