That combination of a lightweight aftermarket chassis and a seriously lively engine helped put Stomp firmly on the map.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan lang=\"EN-US\"\u003eThe Z3R-140 continues that legacy. At its heart is the immense 4-stroke, single-cylinder YX140, using Stomp's SR140C Z40 specification. But the \"R\" in Z3R stands for Race, and this bike has always been about much more than just its engine.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cspan lang=\"EN-US\"\u003eThe lightweight single-backbone chassis keeps mass down and agility high.
