The V-Four-powered machine has been re-tuned  for greater low and mid-range torque, and also receives a new telescopic fork, Pro-arm swingarm, wheels, new, slimmer bodywork and styling. Starting with the 782cc V4-VTEC engine, Honda engineers focused mainly on cam timing and valve duration/overlap to increase low-to midrange power and torque, claiming 104.5 hp @ 10,250 rpm and 55.4 ft-lbs of torque @ 8,500 rpm. Bore and stroke is 72mm x 48mm, with compression ratio of 11.8:1. VTEC valve timing still operates one pair of inlet/exhaust valves per cylinder at low rpm, and then switches to four as revs rise. Honda’s single-mode Traction Control System (TCS) is fitted as standard equipment and is operated from the left handlebar.
