Primary gear ratio -FABBRI RACING performance- Vespa V50, PV125, ET3, PK50, PK80, PK125 - 27-69 = 2.56 (straight toothed)

Fabbri Racing 27/69 primary gear ratio for Vespa Smallframe - CNC-reinforced for powerful engines

Primary reduction ratio from FABBRI RACING for high-performance engines. Suitable for all Smallframe manual engines, e.g. V50, 50N, SS90, PV125, ET3, PK80-125 S/XL/XL2 engines.

Consisting of:

• Primary reduction 27/69 (2.56 similar to original 125cc therefore ideal for high displacement engines and/or very short stepped gearboxes)

• Fabbri Racing CNC clutch basket

• Fabbri Racing CNC cover plate

• Primary springs (reinforced)

• Screw connection

The set has a massively reinforced primary drive, making it durable even for very powerful engines. The CNC-milled cover plate effectively prevents the thin standard plates from breaking through and thus keeps the shock absorber springs in place. Thanks to the high-strength material used, the reinforced clutch basket offers complete safety even on extremely powerful and high-torque engines. A recess in the basket allows the clutch pinion to be replaced without removing the entire primary.
