The Cagiva SST350: A Trail Bike with a Roadster Heart
In the late 1970s, the market for large capacity trail bikes was exploding, but few manufacturers offered a truly unique alternative to the Japanese offerings. Enter the Cagiva SST350, a 341cc two-stroke trail bike that defied convention with its oil-injected engine and exceptional quietness.
The SST350’s design is rooted in its SST roadster heritage, with a well-gussetted duplex frame providing the foundation for this versatile machine. Its steep steering head angle and minimal trail make it an agile handler on both pavement and dirt, while the oil injection system ensures reliable operation even under harsh conditions.
But what truly sets the SST350 apart is its ability to balance performance and practicality. With features like 12-volt battery lighting, a comfortable dual seat, and a quiet exhaust system, it’s clear that Cagiva aimed this bike squarely at the commuter trail rider – and succeeded with flying colors. The result is an exceptional motorcycle that will devour both asphalt and dirt trails with equal enthusiasm, making it an outstanding choice for anyone seeking a capable and reliable ride.
