For 2011, we've given our beloved Apex an overhaul from the ground up delivering improved performance you must experience to believe. Yamaha's EXUP and EPS top the list of revolutionary features you'll find. Our fuel-efficient, high-performance Genesis four-cylinder four-stroke engine received multiple refinements for more peak power delivery and superior performance. The addition of Yamaha's EXUP system enables strong acceleration with linear response across the entire rpm range. Yamaha's Electronic Power Steering system will have you carving tighter, sharper lines with a light linear feeling. At the end of a long ride, you'll feel less fatigue, and with all the new performance characteristics you'll find with the new Apex, that's a good thing, because you'll be begging for longer trails.
