My VFR 750F
VFR750F received many positive reviews and awards while in production, including winning the Best 750 cc sport bike award from Cycle World six years in a row
An excellent street bike, the original Interceptor also posted eight AMA Superbike victories, including the Daytona 200, and finished second in the series. Three years later, Honda gave the Interceptor a complete make-over. First, they added an "R" to the "VF." Next, they redesigned the V-4 engine with a geared cam-drive, offering more peak power. Then they mounted the engine to an aluminum racing frame, covered it with a full fairing and lopped off almost 45 pounds in the process. Finally, in superbike trim.
In the United States Fred Merkel and Wayne Rainey disputed the 1986 AMA Camel Pro Championship, which at the time had both Superbike and F1 races but only one championship, with the best finish of the day counting. Merkel just rode in the Superbike while Rainey did the F1 as well. Merkel won two races and Rainey seven but the championship was won by Flyin' Fred Merkel by only two points.
For 1987 Freds bike was passed to Bubba Shobert who took 3rd place in 1987, being beaten by Wayne Rainey and Kevin Schwantz. The points he earned during the 1987 season gaining him victory in the AMA Grand National. In 1988 Shobert won 3 of the 7 races to win the AMA superbike championship.
A very special VFR750F called the '6X', a full HRC prototype containing titanium valves and magnesium flat-slide carburetors and weighing even less than the factory RVF was first seen raced by Wayne Gardner at Suzuka against TT F1 machinery. Wayne trounced the opposition, smashing his 4 stroke lap record by 1.5s.
The engine developed in the 6X became the basis for the factory racer, the VFR750R.
The VFR750F series all used 748 cc 16-valve gear driven DOHC liquid-cooled 90° V4 engines with carburetor-based air/fuel induction; the bore/stroke remained the same for all 750 models at 70.0 x 48.6 mm (2.756 x 1.913 inches). The engine was made of cast aluminium alloy with the crankcase being divided horizontally, VFR750P and VFR750K models use slightly different crankcases with the lower casing being modified to allow for the gear position indicator in place of the neutral switch. On all the VFR750 models the gear drive for the cams was between the cylinders. Lubrication was via a wet sump with a chain-driven, dual-rotor oil pump; an oil (air) cooler was also fitted. Transmission was a 6-speed, with a constant-mesh, wet multi-plate clutch and chain drive to the rear wheel with the exception of the 5-speed VFR750P which featured a spacer in place of one of the gears.
The VFR750F uses a 180 degree crank, instead of the 360 degree crank used in the VF and VFR750R.
