of the "F" model, via the utilization of different thermostat settings and through the use of two radiators. The lower of the two radiators had 2 fans which drew air through the radiator from the back side, while the upper relied on ram-air, drawn from vents around the headlight opening. The exhaust system was slightly altered, utilizing an exhaust collector box (directly downstream for each of the four header pipes) with slightly augmented output angles for each of the two exhaust pipes compared to the "F" model. This was done in an attempt to increase ground clearance while cornering. The rear suspension (air shock with adjustable damping control) and frame (square-section steel tube type) were direct carryovers from the "F" model, but the front suspension featured Honda's anti-dive system named "TRAC" which stood for "Torque Reactive Anti-dive Control". This system utilized the left brake hangar being pinned to the fork on the bottom mount and allowed to pivot in an anti-clockwise direction, thereby closing a valve in the left fork leg, forcing the damping fluid through a smaller passageway, and increasing the damping rate under hard braking. The left fork leg had a screw-type adjuster with four positions of adjustment which would change the amount of influence this system had under braking. The fork also featured a Schrader-type air valve which allowed air assistance from 0-6 psi to increase the spring rate in the fork. The right fork leg featured a 3 position hand adjustable dial which would increase damping rates. The fork also featured quick-release, swing-away axle clamps for faster tire changes in endurance racing. Many of these features were seen as very exotic for the time, and modern adjustable sportbike suspension can trace design roots to these features. The braking system was improved via the use of dual floating front discs and racing style piston calipers on the ventilated rear disc. This was the first used on the honda cbx 1000 in 1981...then used on the vf1000r (sc 16). Compared to the VF1000F, the VF1000R had completely different bodywork and rider positioning. The "R" model got fully faired, racer replica bodywork with rearset footpegs and adjustable clip-on handlebars. The handlebars were adjustable through a range of 4 degrees in 2 degree increments via a double serrated ring which meshed with the handle and the mounting ring parts of the clip on. Even with the adjustment available in the
