premise: Driving down the road on a mini motorcycle. hypothesis: A motorcycle cruises down the road.
neutral: Motorcycle as stated in sentence 2 cannot be inferred from sentence 1 because sentence 1 specifically states mini motorcycle and motorcycle as stated in sentence 2 can be of any make or size not just mini.  Sentence 1 states driving which does not infer cruises as cruises is basically joy riding and driving is indicative of a specific destination in mind.
