Description
Metrakit Pro Race crankcase
Metrakit now also offers a high-performance tuning crankcase for heavily tuned engines: the Metrakit Pro Race. Made from high-strength cast aluminium, it provides enhanced durability and performance-oriented technical features.
It is based on the original Derbi Euro 3/4 design, perfect for tuners and racers aiming to unlock the full potential of their engine (up to 40 hp). The case can of course also be used for everyday riding.
Note: For use with FL components, you should go for the Metrakit Hyper Pro crankcase.
Features Metrakit Pro race
The original Derbi engine cases are not designed for the extreme loads of tuned setups. Metrakit provides a remedy and offers a reinforced, optimized high-end upgrade that will satisfy even the most demanding tuners.
- Reinforced wall thickness for high loads
- More compact and lighter due to elimination of the starter motor
- More space for large-diameter carburetors
- Improved thermals / heat dissipation
Compatible with crankshafts with enlarged crank webs
- Oversized needle bearing for the balancer shaft
- Oversized crankshaft bearings (6304)
- Prepared for Ø14 mm swingarm shaft (simple drilling required)
- Suitable for V-Force 3 and 4R reed valves
- Compatible with OEM Derbi Euro 3/4 parts
Note: Comes with central gasket and mounting hardware.
Ignition cover
The ignition cover, or alternator cover, has a relatively simple job: it protects the ignition from moisture and the rider from rotating parts.
Ignition cover and performance
On 50cc motorcycles with AM6 or Derbi engine and scooters, internal rotor ignitions are often combined with an ignition cover with cutouts to prevent the ignition from overheating.
On motocross bikes, plastic ignition covers are often replaced with sturdier aluminum covers.
Note: Always remember to use a new ignition cover gasket.
