Metrakit Pro Race Crankcases Derbi Euro 3 / Euro 4, Derbi type cylinder mounting

Description: Metrakit introduces the Pro Race crankcases, made from high-strength cast aluminium. Based on the original Derbi Euro 3/4 design, they are suitable for daily use and essential for tuners aiming
to unleash the full potential of their engines.

As the original Derbi crankcases are not designed to handle power outputs close to 40 hp, Metrakit has developed a reinforced and optimized version. Its strength and technical improvements make it a
must-have component.

Key features:

- Crankshaft mounting with 2 bearings 6304TN9 C3 (20x52mm)

- Oversized needle bearing for the balance shaft

- Compatible with crankshafts of larger diameter

- Prepared for Ø14 mm swingarm shaft (simple drilling, no engine splitting required)

- Lightweight design by eliminating the starter

- Fully compatible with OEM Derbi Euro 3/4 parts

- Designed for V-Force 3 and 4R reed valves

- Improved thermal conductivity

- Reinforced wall thickness to withstand tuned engine stresses

- Oversized crankshaft bearings (6304) for longer service life

Conclusion: The Metrakit Pro Race crankcases combine strength,compatibility, and performance. They are the ideal choice for enthusiasts seeking to improve both the reliability and the performance
of their Derbi engine.

The crankcases are delivered bare, including the central gasket and
mounting bolts.
