Top Performance FL Engine Cases – Minarelli AM6

The Top Performance FL engine cases are the go-to upgrade for taking your Minarelli AM6 up a level. Built to house big-bore FL cylinders (LMR, FAST, MONAYA, ROOST, 8.1), they open the door to serious builds pushing up to ~40 hp at the wheel.

Also compatible with classic stud-mount cylinders (top alloy type).

To maximise intake area, Top Performance deleted the balancer shaft: the reed valve space is huge and sized for a Yamaha Banshee 350 reed valve (available on our site). The cases are sized for racing crankshafts of 46, 47 or 48 mm. A new gear selector bearing is included for smoother shifting.

The pack includes:

• FL engine cases (pair)
• A gear selector bearing
• A specific clutch rod stop
• Fasteners

Benefits:

• 📈 Massive engine potential: up to ~40 hp at the wheel with the right build
• 🎯 Oversized intake, sized for a Banshee 350 reed valve
• 🏁 Accepts 46, 47 and 48 mm crankshafts to match stroke to your project

Note: the Yamaha Banshee 350 reed valve is sold separately on our site. FL cylinders (LMR, FAST, MONAYA, ROOST, 8.1) are not included.
