Combining an 800cc, 45bhp, 74lb/ft of torque turbocharged Diesel engine with shaft drive, a continuously variable transmission and two-wheel drive the EVA Track T-800CDI is a very unique motorcycle. Its raison d'etre appears to be to offer the kind of rugged go-anywhere ability that bikes like the BMW R1200GS promise, but are too fancy to deliver. Capable of running on plain old Diesel, bio-Diesel, plain plant oil or all of the above, the incredibly fuel efficient T-800 (capable of returning up to 112mpg at 55mph) could have the range and flexibility to travel almost anywhere on earth. Diesel will also make it compatible with most of the world's militaries.

Update: We've embedded a short video of the Track T-800CDI after the jump, click through to hear it in all its clattery glory.

That CVT transmission is necessary to keep the motor operating at low revs to boost fuel efficiency. It makes that 74lb/ft all the way from 1,800 to 4,500rpm. It doesn't seem to add significant weight to the T-800; overall dry weight is just 199kg, 4kg less than that BMW GS. At heart traditionalists, we'd have a hard time trusting such a system to be reliable in the back end of beyond, but CVTs have proved nearly bulletproof in operation.

The hydraulic two-wheel drive is similar to the system developed by Öhlins. A hydraulic pump is powered off the gearbox output shaft, then runs an impeller in the front hub. There's limited details on EVA's system, but the Öhlins setup can transfer as much as 15% of power to the front wheel, varying automatically based on the relative position of the throttle to the rear wheel speed.

Like the GS, power is transferred to the rear wheel through a low-maintenance shaft drive/single-sided swingarm. Indeed, the T-800 bears such a resemblance to the GS in terms of purpose, layout and spec that it must be intentional. Compared to that bike the T-800 is slower (topping out at 108mph), less powerful (the GS makes 105bhp and 85lb/ft), lighter, features fully adjustable ergonomics, uses similar rear suspension and employs a nearly identical aluminum luggage system. It's kinda like a round-the-world adventurer started with a GS then made it more suitable for extreme conditions. Which is probably exactly what happened.
