EICMA 2013: 2014 Honda VFR800F

Gracing the new 2014 VFR800F is traction control, ABS, heated grips, adjustable seat height and self-canceling blinkers. 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.

2014 WSBK – Sepang Results

The first ever World Superbike round in Malaysia offered a plenty of drama including both factory Kawasaki riders crashing out on the first lap, a red flagged second race and an overall impressive outing by Aprilia. Under pressure for his lack of results so far this season, Marco Melandri impressed, earning the double for his first career wins on the RSV4 Factory. Aprilia riders led every lap in both races at Sepang, including the red-flagged initial start for Race 2, with Sylvain Guintoli joining his teammate on the podium with a pair of second-place finishes.

Honda’s V-4 History

As Honda prepares its new VFR1200 for its official unveiling, the red-wing company has set up a website detailing its long involvement in V-4 engines. It began back in 1979 with the introduction of the NR500 grand prix racebike. Rather than fielding a 500cc two-stroke engine, Honda used a four-stroke oval-piston V-4 motor – essentially a V-8 with four cylinders that could be revved to 19,500 rpm!
