A big-bore 270cc is good for a vet guy who wants the lightweight feel of a 250F, but maybe not the power of a 450. Also, for some less honest people out there, this could be a less expensive option, rather than building a full-on race engine. Jay Clark does a ton of these builds, but he wanted a bike he could use to beat up on his buddies on any given weekend.
