{"product_id":"triumph-pre-unit-twins-crowood-motoclassics-series","title":"Triumph Pre-Unit Twins (Crowood Motoclassics Series)","description":"Triumph's pre-unit twin-cyclinder motorcycles were produced from 1938 to 1962, with engine sizes of 350cc, 500cc and 650cc.  Ridden both on the road and in competition , the bikes formed the basis for Triumph's success through the 1940s to the 1960s.  With iconic names such as Speed Twin, Tiger 100, Trophy and Bonneville, the pre-unit Triumphs came as sports bikes and tourers.  With their superb styling and reliable engines, there were a favourite both at home and abroad. Triumph Pre-Unit Twins looks at the history and development of these bikes, and describes the various models that make up the range. It gives a detailed technical analysis of each model.  Interviews with past and present owners give riding impressions of the bikes both today and back in the 1960s.","brand":"The Crowood Press UK","offers":[{"title":"Default Title","offer_id":31911972831303,"sku":"B04249","price":49.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0057\/9813\/3831\/files\/351c4180-0e60-4db9-8123-e85a55642068_20da9.jpg?v=1772278127","url":"https:\/\/www.midlifeclassiccars.com\/bs\/products\/triumph-pre-unit-twins-crowood-motoclassics-series","provider":"MidlifeClassicCars.com","version":"1.0","type":"link"}
