1981 - 1988 Suzuki GS 450 L
The base of the bikes was the two-pillager of the popular GS 400, whose origins originated from 1976. But you can make everything better and so the engineers gave the Twin a general cure. A cylinder drill of 71 mm was installed and the stroke reduced from 60 to 56.6 mm. This resulted in an increase in displacement to 448 cc .
