Cylinder Head TBI 125 Factory

125 TBI High-Performance Cylinder Head

This cylinder head is not a mass-produced item – it's pure racing technology. CNC-machined from high-strength 7075 aluminum and hard-anodized for maximum durability. Developed with the highest precision for improved flow, optimal power delivery, and higher detonation resistance even under extreme conditions.

The core is the combustion chamber insert made of a high-tech copper alloy, as used in Formula 1. This ensures perfect heat dissipation and cooler engine operation, guaranteeing consistent performance and additional stability – whether on the racetrack or in tough off-road use.

With a combustion chamber volume of 11.60 cc, this head is precisely designed for maximum power and clean combustion. Every millimeter has been uncompromisingly engineered for performance.

Designed for flat pistons with standard squish clearance (0 / -0.1mm).

Features:

• CNC-machined from 7075-T6 aerospace aluminum
• Hard-anodized for extreme durability
