In some respects, this comparison has a powerful subtext regarding a Battle of the Powerplants. Seriously, these are two of the most interesting and best-running engines you can buy in streetbikes today. The redesigned 1050cc Triumph's throaty growl was first heard in the 2005 Speed Triple, made its way directly into the Sprint ST and now the Tiger. It is fuel efficient, hits like a hammer at low revs, then keeps on pulling with a much broader torque band than the Duc, while offering 12,000-mile valve-adjustment intervals. The DS1100, meanwhile, expanded profoundly the likeability of Ducati's desmodue air-cooler. It runs smoother than ever, has way more bottom-end snap and seems to pummel unbridled exuberance from every fuel molecule. All this while turning in 45 mpg, even in our heavy throttle hands! And good news for Ducati fans, valve-adjustment intervals are now 7500 miles, with costs for maintenance said to be cut by 50 percent.
