An all-new open-class Adventure bike, the Tiger Explorer that will challenge BMW is the big news. The largestdisplacement adventure bike the Hinkley company has built. Details on all three new models are scanty so far, but Triumph tells us this model gets a new steel chassis, a 19-inch front wheel (and 17-inch back), a class-leading 950-watt generator, shaft drive, optional hard luggage, ABS (with an ‘off’ switch), adjustable seat height and a burly three-cylinder engine “in excess of 1200cc.” If Triumph applies the same long-stroke tuning trickery to its 1050cc engine it used with the excellent Tiger 800 (a stroked 675), we don’t expect much more peak horsepower compared to the 1050, but there will be a lot more torque — maybe even the most of any Adventure bike. There is no word on weight, availability or pricing.
