Not only does the Track T-800CDI hold up admirably over long distances, but it also looks downright sleek and modern while doing so. Bearing striking resemblance to the Yamaha Super Tenere, this top diesel motorcycle produces up to 45 hp and 78 ft-lbs of torque out of its turbocharged 3-cylinder engine, getting the bike from 0-60 mph in under 4 seconds. That’s joined by Brembo brakes, long-travel suspension, a trellis frame, and an upright, ergonomic stance. Only 50 have been sold to date, and snagging one will run you about 25K. Worth noting is that the blueprints are also for sale, just in case you want to build your own to add to your collection of diesel bikes.
