Since right from the very start, Stage6 are committed to develop performance-enhancing tuning parts and don’t shy away from tackling new tasks. They are getting into the market for geared mopeds / supermotos now, this is a tuning pack for Derbi Euro 2: Tuning Kit cylinder + crankshaft Stage6 BigRacing 77cc Derbi Euro 2.

Includes:

  • 77cc cylinder, aluminium, 50mm bore, with 5 transfer ports and 32mm bridged exhaust port
  • 1-ring Vertex piston, d. 50mm
  • High compression cylinder head, monobloc, aluminium
  • Gasket set (base and head gaskets)
  • HPC crankshaft original stroke 12mm piston pin
  • Crankshaft bearings and oil seals SKF C3 polymer cages

The cylinder features a rather basic and inconspicuous exterior, but we all know that appearances can be deceptive. We’re talking genuine „Big Bore“ here – cylinder layout is not based on a modified standard model that was milled open to create a bigger bore, but was designed as a Big Bore right from the start, with matching transfer ports and a bridged exhaust port big enough to support the excess performance.

The BigRacing cylinders impress with ease of installationoutstanding performance, and high reliability.   

– Installation is very easy, crankcase milling or any other modification are not necessary. Squish clearance is pre-set to a value optimized for the respective engine type. 
– In terms of output, the BigRacing cylinders knock it out of the ballpark: we measured a whopping 23 PS and 13 Nm on our P4 test bench using a standard set-up (24mm carburetor, original ignition, racing exhaust etc.). 
– Port timings are relatively low, cooling system volume is quite large and the piston is a top quality Vertex piston. All of these factors contribute to the cylinder’s high dependability and robustness, provided that set-up and adjustments are appropriate. 

The exterior is a replica of the original cylinder with a 49cc stamp; don’t worry, this is definitely a 77cc cylinder!

Attention: For the assembly of this cylinder kit, you have to use longer stud bolts (M7x120mm).

Not road-legal.
