Description
Stage6 Tuning Kit cylinder + crankshaft Big Racing 88cc stroke 45mm Derbi Euro3 / Euro4. The tuning packs we have carefully assembled for you guarantee maximum performance without you having to worry about the right combination of the individual components.
The tuning kit consists of the following parts:
- 88cc cylinder d.50mm / stroke 45mm, aluminium, with 5 transfer ports and bridged exhaust
- 1-ring piston d.50mm Vertex
- aluminum cylinder head, one-piece, high compression
- gasket set (base and head gaskets)
- HPC crankshaft Stage6 w. 45mm stroke and 12x17x15mm small end bearing
- SKF C3 bearing polymer cage Stage6 + oil seals

The BigRacing cylinder from Stage6 is intended for everyday use, but can also be used for tuning projects. The port timings are relatively low, the exhaust is generously sized, which makes for easy tuning and smooth performance over the entire rpm range; it also provides a good basis for performance-enhancing tuning measures.
The crankshaft is a Stage6 HPC crankshaft, with 45 mm stroke. Thanks to the high-quality materials and extremely precise balancing, the crankshaft can withstand very high loads of up to 16,000 rpm.
In combination with the appropriate components (28mm carburetor, high-end / racing exhaust, reinforced clutch, …) this kit can reach 27 hp and more.
