Advantages:
Quality & light:
Manufactured according to Piaggio procedures, excellent casting quality, precise magnet cores. Provides powerful current and bright light even at low speeds. Can be perfectly combined with BGM alternators for even better light output. Sturdy, precisely riveted cone.
Blade shape & Cooling:
Optimized blade shape (inspired by PK models), ideal for modern engines with higher engine speeds and aluminium cylinders. Still thermally perfect even at full throttle (e.g. Polini 207 cast iron).
Performance & acceleration:
Up to 1-2 hp more power (depending on the engine), better acceleration due to concentrated masses. Sport (1600 g) for maximum dynamics, Touring (2300 g) for balanced performance.
Use:
DualFit grooves:

Fits Largeframe (PX, Cosa, LML 2-stroke) and Smallframe PK XL with large cone (shaft seal 20x32x7 mm, nut M12). Not compatible with Smallframe engines with small cone (19x32x7 mm, M10 nut). Ideal for conversions to more stable crankshafts with electronic ignition.
