Why the Pinasco 177cc Cylinder Kit is One of the Best Upgrades for Classic 2-Port Vespas
If you own a classic 2-port Vespa, you'll know that while these iconic scooters are fantastic to ride, modern traffic can leave the original 125cc and 150cc engines feeling a little underpowered. Whether you're riding through town, tackling steep hills or planning longer touring adventures, a little extra performance can completely transform the riding experience.
That's exactly why the Pinasco 177cc Cylinder Kit has remained one of the most popular and respected upgrades for vintage large frame Vespas for decades.
A Proven Italian Performance Upgrade
Pinasco has been producing performance parts for Vespa scooters since the 1960s and has built a reputation for manufacturing reliable, high-quality products that deliver genuine improvements without sacrificing everyday usability.
The Pinasco 177cc kit is specifically designed for classic 2-port large frame Vespa engines, making it an ideal upgrade for owners who want more power while maintaining the character and reliability of their original scooter.
Unlike many race-orientated cylinder kits, the Pinasco 177 has been developed for real-world riding, offering smooth power delivery, excellent reliability and impressive torque throughout the rev range.
What Makes the Pinasco 177cc Kit Different?
Rather than chasing maximum horsepower, the Pinasco kit focuses on producing usable performance exactly where most riders need it.
By increasing the engine capacity from the standard 125cc or 150cc to 177cc, the engine develops noticeably more torque, making the scooter much easier and more enjoyable to ride.
The benefits are immediately noticeable:
- Stronger acceleration from low revs
- Improved pulling power on hills
- More relaxed cruising speeds
- Better performance with a passenger
- Less need to constantly change gear
- Improved overtaking confidence
- Excellent reliability for everyday use
For many riders, it makes their classic Vespa feel like an entirely different machine while still retaining its vintage charm.
Built for Touring as Well as Everyday Riding
One of the biggest reasons the Pinasco 177 has become such a favourite is its versatility.
Whether you're commuting, enjoying weekend rides or embarking on European scooter tours, the extra torque makes riding considerably more relaxed.
The engine doesn't need to work as hard to maintain cruising speed, meaning lower stress on the motor and a far more comfortable ride over long distances.
It's one of those upgrades that you appreciate every time you open the throttle.

The Pinasco cylinder is manufactured from high-quality cast iron, a material renowned for its durability, excellent wear resistance and ease of maintenance.
