Engine[edit | edit source]
The engine was a liquid cooled twin, four-stroke. A 67.0mm bore x 56.6mm stroke result in a displacement of just 399.0 cubic centimeters. Fuel was supplied via a double overhead cams/twin cam (dohc).
Drive[edit | edit source]
The bike has a 6-speed transmission. Power was moderated via the wet multiplate with coil springs.
Chassis[edit | edit source]
It came with a 110/70-zr17 front tire and a 140/70-zr17 rear tire. Stopping was achieved via single disc in the front and a single disc in the rear. The front suspension was a 41mm conventional telescopic while the rear was equipped with a pro-link monoshock with nine-position spring preload adjustability. The CBR400R was fitted with a 3.96 Gallon (15.00 Liters) fuel tank. The bike weighed just 401.24 pounds (182.0 Kg). The wheelbase was 55.51 inches (1410 mm) long.
1983 Honda CBR400F[edit | edit source]
With that weight disadvantage, the CBR400F can't afford any power disadvantage as well. And although its air-cooled, 16-valve, inline-Four doesn't look special, new technology lurks inside the ordinary exterior, hinted at only by the REV acronym cast into the cylinder head. The REV system mechanically disconnects one inlet and one exhaust valve from each cylinder at low engine speeds, and sets them operating again at high rpm. This allows radical cam timing without killing low-speed power.
1987 - 2001 Honda CBR 400 RR[edit | edit source]
The Race Replica of the CBR 400 has a liquid cooled, four stroke, four cylinder engine with a displacement of 399cc, this engine being able to develop 59 horsepower at 12500rpm.
