Announced in 1959, Triumph's entry into the scooter market was the fittingly- named 'Tigress'. Fitted with a Turner-designed, 250cc, four-stroke twin motor and a well-engineered and innovative chassis and suspension and going as well as it looked, it should have swept the market, but was initially subdued by Triumph's delivery problems. It was also available with a smaller engine as well as BSA-Sunbeam badging. 998 BAC is a well-preserved and original example with only around 13,000 miles recorded. Last registered in 1998, it has the usual paint flaking but turns over smoothly and should restore well as an example of a much sought-after, fast and powerful scooter.
