These line drawings are the best images yet of the 2011 Triumph Adventure(s). Today comes news that there will be two versions: one equipped for the road with a 17-inch front wheel and firmer suspension, one specializing in dirt with a 21-inch front wheel.

According to the official leaked information (oxymoron much?) both bikes will share the same aluminum tube frame (similar to that on bikes like the Triumph Speed Triple), swingarm, ABS brakes and 800cc-ish three-cylinder motor based on that of the Triumph Daytona 675. According to the official leak, that 675’s motor has had its capacity increased by lengthening the stroke, a move intended to fatten the torque curve at low revs and make the engine less peaky.

The bike in these sketches is the road-going version, note its distinctly sportsbike-sized tires and lack of a honkin’ front mudguard. Hopefully the dirt version will also add something in the way of engine protection, that bash plate doesn’t look like it could stand up to much bashing.

As cheesily voiced over in the video, also expect the two bikes to differ in riding position, with the road version putting more of your weight over the front end than the off-road, which will be more upright.
