The racing crankshaft from POLINI for classic Vespa models offers a racing level - on the road and on the race track.
For decades, racing crankshafts from POLINI have stood for Italian engineering and uncompromising performance. Whether for ambitious tuning projects, sporty everyday use or tough racing - with a POLINI Crankshaft, you are opting for maximum reliability, high revving pleasure and a clearly noticeable increase in performance.
- Finely balanced crank webs
- Reinforced Conrod and precision bearings
- Optimized timing
- High-quality materials and workmanship
POLINI offers different racing crankshafts depending on the intended use, but they all have many things in common. Finely balanced crank webs minimize vibrations and improve the stability of the Engine. Reinforced Conrods and high-quality roller bearings ensure a longer service life, especially for tuned Engines. The optimized timing ensures better filling and therefore a noticeable increase in performance. POLINI attaches great importance to precision manufacturing and uses only high-quality materials for optimum results in all areas of application.
The differences between the racing crankshafts are not just in the name:
POLINI "FOR RACE" (ROAD)
These crankshafts are suitable as high-quality replacements for standard crankshafts and are ideal for engines with sports or mid-race Cylinders that are designed for touring-oriented road tuning. They are designed for higher loads, have reinforced Conrods and precise balancing. Optimized intake timing and often also flow-optimized crank webs noticeably improve engine performance, especially in the medium speed range.
POLINI "RACE"
These shafts are designed for racing and high-end tuning for engines with extremely high engine speeds and performance. CNC-machined Conrods, special alloys and thermal treatments ensure maximum strength under extreme conditions. The balancing has been further improved to minimize vibrations even at very high engine speeds. Timing and crank web design are consistently geared towards peak performance, at the expense of torque in the lower range and suitability for everyday use.
Conclusion: Crankshafts are subject to the highest stresses in combustion engines. It is precisely for this reason that the highest quality should be emphasized. POLINI is well aware of these stresses and offers a first-class product with its Crankshafts.
