S3 Extreme Enduro low compression - orange KTM Cylinder head and insert kitRef : SPART00314A / 1101434

The S3 Extreme Enduro cylinder head and insert kit in orange is designed for riders who want to temper the raw power of 2-strokes and gain control on tricky terrain. Its low compression design makes the power curve smoother and facilitates revving, which helps to better modulate acceleration in the technical sections of extreme enduro.

• Improved traction and more progressive handling
• Better control at low revs, ideal for slow passages and obstacles
• Optimised weight reduction and cooling thanks to a studied geometry
• Specific orange finish that enhances the race look of KTM/Husqvarna machines

The kit is aimed at discerning riders who prioritise tractability over maximum power. It helps to reduce jerks and facilitates starts on slopes or getting back on track in muddy conditions, without promising specific performance figures.

Included in the kit: Extreme insert, cylinder head, O-rings. Compatible with current 300 TPI models — for example, KTM 300 EXC TPI SIX DAYS (2022), HUSQVARNA TE 300 i (2022), and GAS GAS EC 300 (2022). Professional installation is recommended to ensure sealing and proper adjustment.
