with white and black plastic surround on the initial US release models in order to satisfy what most major manufacturers thought would be a requirement of US street legal vehicles in the near future. The legislation never passed, and Honda included the very desirable dual round headlight on the 1986 US models. The VF1000R had three major model revisions. The first model which ran from the beginning of production in 1984 to April 1985 was coded the RE model (internal Honda factory code) The second model, denoted with the RF suffix, was produced from 1985 to the end of the worldwide production in 1988. The RG model was the final model and was produced from 1986 through 1987 Differences between the models were mainly cosmetic, but a number of important mechanical changes were made to increase reliability when Honda transitioned from the RE to the RF model designations. The RF model saw improved cooling through fairing redesigns in relation to the RE, as well as the addition of a double oil sump system, complete with anti-slosh plate mounted in the oil pan (compared to the single pump system in use on the RE model. This was done in order to combat oil starvation during cornering, as well as ensure that the cams and heads of the motor were receiving adequate lubrication. The RE models initially had trouble with camshaft wear. The addition of the second oil pump as well as a redesign of the camshaft clamps was done in order to improve the situation. The RF model also got a redesigned oil pan with taps for an oil cooler and the respective lines, in order to help with the high temperatures seen in the oiling system. The final changes to the RF model from the RE, was the change in sidecover design, from a solid plastic version with cutout vent, to a mesh version. This allowed the inspection of battery fluid level, as well as coolant level without removing the covers. Changes from the RE to the RF in terms of color scheme included eliminating the Blue/Red/White (with blue seat) color scheme and continuing production with only the Red/White/Blue (with red seat) HRC replica paint scheme. The RF model was the first model to be sold outside Europe. The RG model carried very few modifications in relation to the RF model, with exceptions being the recoloring of the clip on
