Selva - Oyster 6
Technical details
Producer: SELVA (IT)

Another four-stroke champion to test. The single-cylinder 5/6 Hp Oyster is the only product in Europe with an OHC (Over Head Cam) structure, the overhead camshaft that reduces exhaust emissions to a minimum.

It is a high performance, light, compact product with low fuel consumption. Clean as a 4-stroke and easy to manage as a 2-stroke. (selvamarine@selvamarine.com)
