From its 790cc power bank, the 2005 Triumph Bonneville scoots along efficiently with a five speed manual transmission. The Bonnie has no issues in quickly moving away from standstill traffic, getting off the line at red lights, or easily achieving legal roadway speeds. It is a capable cruiser at highway speeds, however, its modest weight will feel the push and pull of the air when moving at faster speeds, and around heavy traffic. What it lacks in freeway girth, it easily makes up for with nimble maneuverability, and impressive engine efficiency. Daily commuters will love the 2005 Bonneville's ability to get in and out of thick traffic, to split lanes, and to find the front of the line at stop lights. Most impressive is the money that will be saved at the gas pump. The 790cc parallel twin is a fuel-friendly machine, testing at 48 mph city, and 57 mph highway. Rarely does fun equate to savings at the pump, but the 2005 Triumph Bonneville T100 flips such a notion on its head.
