Pinasco SMART Engine Case for Vespa 200 – with CNC Reed Valve Intake for SI Carburetors (24 mm, 26 mm, 28 mm)

Innovative engine base for maximum performance and everyday usability

With the new SMART engine case, Pinasco introduces a modern upgrade for Vespa 200 engines. The main advantage: it allows the installation of a classic SI carburetor (24–28 mm) in combination with a high-precision reed valve intake – ideal for powerful builds without compromising on daily use or original aesthetics.

Highlights of the new reed valve system

✅ Precision-built: The reed block is CNC-milled from Ergal and co-molded in rubber – for a perfect seal without additional gaskets.

✅ Durable & low-maintenance: The soft rubber base prevents premature wear of the carbon reeds.

✅ Performance optimized: High-quality carbon reeds with excellent flexibility and an integrated stainless-steel stopper to control movement.

Significantly improved engine behavior

The Pinasco SMART engine case is designed for greater efficiency and ride comfort. The reed valve system ensures smoother power delivery from low RPMs, reduces fuel consumption, and eliminates common rotary-valve issues like backflow into the carburetor.

Technical features at a glance

✅ Compatible with SI carburetors (24 mm, 26 mm, 28 mm): Optimized for classic Vespa carbs – e.g., Pinasco SI 28.

✅ Innovative oil seal seat: Pinasco’s special seal system is mechanically fixed between bearing and case using three steel brackets – for long-lasting sealing and precise bearing fit.

✅ Reinforced bearing seat: Additional strengthening ribs in the crankshaft and secondary shaft areas ensure maximum stability – perfect for high-performance setups.
