The Power1 Race cooling fin is an extra lightweight variator cooling fin for mopeds and scooters with a Minarelli engine. Due to the lower weight, the variator runs smoother and the CVT can respond faster — a popular upgrade for those who want more performance from an MBK or Yamaha with a horizontal or vertical Minarelli block.
The cooling fin fits the Minarelli engine block in both the horizontal and vertical versions. This makes it suitable for a wide range of models: the MBK Booster (horizontal block), the MBK Nitro, and the Yamaha Ovetto (vertical block). Before installation, check if the engine type matches — horizontal (hor) or vertical (vert).
Power1 is a well-known name in the aftermarket tuning sector for small two-strokes. The Race variant is aimed at a lower rotating mass without compromising the cooling capacity of the variator.
