S3 Extreme Enduro Low Compression Cylinder Head and Insert - Orange KTM/Husqvarna (Ref. XTR-985TPI-250-O)

Designed for extreme enduro, this S3 kit combines a machined cylinder head and a low compression "Extreme" insert to make the engine easier to handle on technical terrains. The configuration aims to improve traction and power control, promoting smooth starts and throttle management in tricky areas.

• Better traction and more precise handling at low/mid revs
• Softer engine response to the throttle, suitable for slow lines and obstacles
• Lightweight design and visible finishes (orange anodising) for a racing look
• Complete kit supplied: Extreme insert, cylinder head, and O-rings

The S3 cylinder head is designed to optimise heat dissipation and minimise weight through specific machining and suitable materials. This kit is primarily aimed at 250 TPI machines from KTM, Husqvarna, and GAS GAS (e.g. KTM 250 EXC TPI SIX DAYS 2022, HUSQVARNA TE 250 I 2022, GAS GAS EC 250 2022) — please check compatibility with your model before installation.

Ideal for riders looking to master power on extreme enduro courses, this kit offers a plug-and-play solution to adjust the engine curve without heavy modifications.
