074900/1 CYLINDER ATHENA RACING aluminium thermal group D.47.6 long stroke 43mm air-cooled MINARELLI HORIZONTAL, pin
80cc Sport Pro Athena cylinder for vertical Minarelli engines, long stroke (43mm). Delivered in kit:
- Nikasil coated aluminum cylinder, with 5 overflows and single exhaust
- 1 ring piston, 12 mm
- one-piece, high compression cylinder head
- Gasket kit for mongge and squish
The 80cc Sport Pro is the big brother of the 70cc Sport Pro Kit from Athena and is very similar to it. However, the cylinder must be used with a 43mm long stroke crankshaft (with 85mm connecting rod).
Of course, the additional displacement also brings more power. Like the 70cc Sport Pro, the 80cc has good torque, especially in the mid-range, and the acceleration is really good. In combination with a 21mm carburetor and a suitable racing exhaust, 14 / 15 hp (on Minarelli) can easily be achieved. Another plus: the cylinder is excellent for tuning and screwing, the quality is first class.
Note: As with all aluminum cylinders, the squish edge must be adjusted
To be combined ONLY AND EXCLUSIVELY with ATHENA RACING 43mm long stroke crankshaft item S410485320004
