context_page_description: A snowmobile, also known as a motor sled, motor sledge, skimobile, snowscooter, Ski-Doo, or snowmachine, is a motorized vehicle designed for winter travel and recreation on snow. It is designed to be operated on snow and ice and does not require a road or trail, but most are driven on open terrain or trails. Snowmobiling is a sport that many people have taken on as a serious hobby.
  Older snowmobiles could generally accommodate two people; however, most snowmobiles manufactured in the last 25 years have been designed to only accommodate one person. Snowmobiles built with the ability to accommodate two people are referred to as "2-up" snowmobiles or 'touring' models and make up an extremely small share of the market. Snowmobiles do not have any enclosures, except for a windshield, and their engines normally drive a continuous track at the rear. Skis at the front provide directional control.
  Early snowmobiles used simple rubber tracks, but modern snowmobiles' tracks are usually made of a Kevlar composite construction. Originally, snowmobiles were powered by two-stroke gasoline internal combustion engines and since the mid-2000s four-stroke engines have also entered the market.
context_section_description: Alpina Snowmobiles are manufactured in Vicenza, Italy, by Alpina s.r.l., a manufacturer of various on-snow implements that had been building dual-track snowmobiles since 1995.
  There are two manufacturers of dual-track snowmobiles. One is Alpina and the other is a Russian sled called Buran (Bombardier discontinued manufacturing its dual-track model, the Elite, in 2005).
  Models
  Alpina manufactures one basic dual-track snowmobile design. In 2002 the Sherpa was introduced and is the model name for the four-stroke machine. Prior to introducing the Sherpa, Alpina offered a two-stroke series designated the Superclass. The four-stroke Sherpa is currently the top machine in production. A new version of the Superclass has been released in 2017, with a lot of innovations and a new four-stroke engine.
  The Sherpa and Superclass series shared the same basic dual-track platform, twin 20 in × 156 in (510 mm × 3,960 mm) tracks with dual skis up front.
  Power for the Sherpa is supplied by a 1.6L in-line four-cylinder gasoline automotive engine. The new Superclass power is provided by a 1.2L 3-cylinder four-stroke gasoline engine.
  Features
  The Sherpa and Superclass are designed as working snowmobiles for carrying supplies, pulling cargo sleds, pulling trail grooming implements, carrying several passengers, and negotiating deep snow.
  Engine and transmission combination are designed to deliver optimum power to pull or carry large loads while top-end speeds are kept below 52 mph (84 km/h), depending on the model. The large footprint of the dual tracks and dual skis allows the Sherpa and Superclass to "float" on top of deep snow and not sink in and get stuck.
