One of the attractions of pushrods is that they keep the engine short from top to bottom. Indeed, Yamaha claims that despite its ultralong 113mm stroke, the 1602cc engine, at 21.1 inches tall, is the shortest big twin available. One sign of its Asian roots is the 97.76-cubic-inch displacement, which stops just 37cc shy of 100 cubic inches. An extra 2mm added to the 95mm bore would have given Yamaha's copywriters one more thing to brag about, but the displacement target was seen in metric terms rather than American. Since the cylinders feature low-friction, high-heat-transfer, ceramic-composite liners over an aluminum base, overboring won't be easy. Some will see the 48-degree V-angle as an effort to mimic Harley. But this engine is much smoother than any 45-degree Harley twin, so you can't argue with the design decisions. In fact, the most amazing thing about this engine is how smooth the bike is without counterbalancers or rubber engine mounts. No doubt the tremendous mass of the crankshaft (a hefty 45 pounds) helps smooth it out, and the engine is a long way from the handlebar.
