Since its inception, Stage6 are committed to develop performance-enhancing tuning parts and don't shy away from tackling new tasks. As of now, they are getting into the market for geared mopeds by introducing the Stage6 Cylinder Kit Big Racing 88cc for Minarelli AM6.
The cylinder kit includes:
- 88cc cylinder, aluminium, 50mm bore, 45mm stroke for 90mm connecting rod, 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)
The cylinder was developed in close cooperation with the MXS Racing experts; by benefitting from their considerable experience of gearshift mopeds and drawing from their own extensive technical know-how, Stage6 was able to design a thoroughly convincing new tuning cylinder.
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 installation, outstanding 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 25,2 PS and 15,4 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.
Displacement is 88cc (50mm piston / 45mm stroke / 90mm conrod) and is accordingly not street-legal (in many countries). You'll have to use a long-stroke crankshaft and longer stud bolts (M7x120mm).
The exterior is a replica of the original cylinder with a 49cc stamp; don't worry, this is definitely an 88cc cylinder!
- you'll need long cylinder bolts (M7x120mm) to mount this kit.
- depending on year of manufacture, you might have to make room for the connecting rod (milling).

great performance, but bad luck with it. - Review by Skillz
consistently getting 27 whp with a hpi ignition, 32mm stage6 carb and custom made exhaust with incredible torque. sadly my something in my engine has broken which ruined 2 of these wonderfull cillinders.
the only negative is the metal headgasket which, i had to reorder once duo to leakage.
