Why choose this kit? 

Nikasil-Coated Forged Alloy Barrels with Steel Liners:
Provides optimal slide characteristics and enhanced durability.

Optimized Forged Piston:
Manufactured using a specialised forging process for superior performance.

Desaxes Pin Offset for LH/RH Fitment:
The desaxing shifts the contact point before TDC, reducing piston wear and engine noise.

FEM-Optimised Centre of Gravity & Weight:
Finite Element Method calculations are used to optimise balance and weight distribution.

Special Bridged Design for Enhanced Stability & Longevity:
Offers superior structural integrity for lasting performance.

Precision Milled & Treated for Weight Reduction:
Advanced milling techniques reduce weight without compromising strength.

Deeper Valve Pockets (Inlet: Large, Outlet: Small):
Engineered for compatibility with high-lift camshafts to maximize performance.

Advanced Piston Rings:
Designed to minimise oil consumption and blow-by for efficient operation.

Compatible with VarioCam Plus:
Ensures seamless integration with VarioCam Plus for optimized engine control.

High-Performance Power Upgrade:
Delivers maximum power, torque, and agility for superior driving dynamics.

Thoroughly Tested on RS-Tuning Dyno:
Developed and rigorously tested to ensure optimal performance and reliability.
