Stage6 70cc Racing MK2 Cylinder Kit – 10mm Piston Pin, Minarelli Horizontal LC (Yamaha Aerox / MBK Nitro)

The Stage6 Racing MK2 70cc Cylinder Kit is the successor to the renowned Stage6 70cc Racing model. Completely redesigned, it offers significantly improved out-of-the-box performance and durability.

Compatibility

Designed for 50cc scooters equipped with a Minarelli horizontal LC engine, including Yamaha Aerox and MBK Nitro models.

Cylinder Design – Stage6 MK2 Racing

This updated version features a new high-strength hard chrome bore plating and an innovative 6-port transfer design (previously 5), enhancing cylinder filling and overall efficiency. The piston now has a domed crown and a 0.8 mm piston ring, optimizing combustion and improving heat dissipation.

Thermal management has been refined across the board — with a bridged pentagonal exhaust port, internal cooling ribs, and a one-piece cylinder head with integrated scavenging channels. Port timings are 190° / 130°.

Performance

The Stage6 Racing MK2 delivers 17–19 hp in standard setup — around 2–3 hp more than its predecessor — and can exceed 20 hp with further tuning. It is one of the most powerful 70cc cylinder kits available on the market today.

Recommended Setup

To achieve maximum performance, we suggest using:

  • A reinforced crankshaft
  • A carburetor of at least 21 mm diameter
  • A high-performance racing exhaust

Installation Tips

Before installation, clean the engine thoroughly and inspect all components. Replace the spark plug and small end bearing. Adjust carburetor settings as needed.

  • Recommended squish clearance: 0.75–0.85 mm
  • Run-in period: approx. 300 km with 1:33 oil mixture

Important Notes:

  • Original exhausts are not compatible with this cylinder.
  • The temperature sensor (including thread) must not exceed 18 mm in length, or it may contact the cylinder head.
  • Without homologation (in some countries).

Scope of Delivery:

  • Aluminium cylinder (47.6 mm bore)
  • 1-ring piston with 10 mm piston pin
  • One-piece cylinder head
  • Complete gasket set
