One of the few bits of good news in the motorcycle industry these past few years, at least in America, is that many of the too-cool-for-the-States Euro-only models have finally dropped anchor and headed to the New World. The U.S. gets one such ride, Yamaha’s FZ8, as a 2011 model. Motorcycle USA got a first taste of the new Fazer on a 100-mile run in California’s Santa Monica Mountains, discovering a fun-to-ride and versatile new middleweight.

The FZ8 expands what Yamaha dubs its Total Sportbike line, a designation applying to the high-performance Supersport R1 and R6, as well as the Sport-Touring FJR1300. In between are models Yamaha designates as its Sport models: the fully-faired FZ6R, half-faired FZ1 and the naked FZ8.

Contrasting their best-selling status in Europe, naked street bikes have struggled in the American market. Yet Yamaha sees its FZ8 as servicing a growing segment. Although overall motorcycle sales have tanked since the 2008 economic crisis, the general market distribution remains more or less the same. Citing data from the Motorcycle Industry Council

Other market indicators deemed favorable for the FZ8 include a growing trend of riders no longer purchasing multiple specialist bikes, but instead investing in a single, more versatile mount. Add in Yamaha’s own customer feedback, which put Rider Position and Price/Deal as their most important purchasing reasons, and Yamaha makes a strong case for its new naked standard.

The FZ8 sources a familiar looking Inline Four, which shares the pre-crossplane R1 pedigree of its larger-displacement FZ1 sibling. The engine cases are in fact identical with FZ1, along with the 53.6mm stroke. But the FZ8 displaces 779cc courtesy of its sleeved down 68mm bore (77mm on FZ1). The FZ8 mill further diverges with a new four-valve cylinder head (five-valve head on FZ1) and higher 12.0:1 compression ratio. Mellower cam profiles and

Variable length intake funnels further refine the engine’s power characteristics. No, it’s not the movable YCC-I system from the R1, rather the outside cylinders are 125mm long, while the middle two cylinders route air from the 7.8-liter airbox through 150mm length funnels. Other internal changes include a narrower throttle bore than the FZ1. The other major change from the FZ1 mill is a lighter crankshaft, with Yamaha claiming a 30% reduction in inertial mass. While giving the engine a quick revving character and smooth throttle response, the company touts the crank’s the reduced rotational force “contributes to light and responsive handling.”

Well-suited to a bike pitched as a step-up model, the engine’s broad powerband has something for all skill levels. The low end churns out ample, yet manageable power, complemented by a forgiving throttle input. Approaching 6K on the tach and a fantastic mid-range zing kicks in. Squeeze the throttle between 6 and 9K and riders had best have firm grip on the controls, because it hauls. Fueling across the powerband is immediate without being abrupt, a very tricky formula to master. The engine’s smooth character holds throughout the revs as well, with no rattling or overt vibes until it buzzes up near the 11.5K redline.
