Manufacturer reference: PWR-1208-250-U
Product: S3 Cylinder Head - High Compression (Brand S3) — Category: Cylinder Head — Universe: Cross

Designed for motocross riders looking to refine engine response without compromising on size, the high-compression S3 cylinder head optimises the combustion chamber for a more efficient explosion. Its competition-oriented geometry promotes a sharper throttle response and a more pronounced rev-up, useful on fast sections and for acceleration.

Key benefits:

• Sharper acceleration response than the original equipment
• Better rev-up to exploit the top of the rev range
• Design that helps reduce operating temperatures
• Lighter than some standard cylinder heads, for a significant weight saving
• Neat finish and machined look, suitable for a competition bike

Supplied with: insert, cylinder head, and O-rings.

Compatible with several Sherco 250 SE-R models (application examples):

• SHERCO 250 SE-R RACING (2022)
• SHERCO 250 SE-R FACTORY (2022)
• SHERCO 250 SE-R SIX DAYS (2018)
