The US 1983 model Vision fixed most of the '82's faults, with an improved carburetor eliminating the stumble, and air adjustable front forks firming up the ride and improving the roadholding. The full fairing, with adjustable hot and cold air vents, effectively shielded the rider. Minor carburetor improvements brought the engine’s unique combination of responsive high-revving clear up to its 10,000 R.P.M. redline and massive torque at any RPMs to the fore. The oversquare bore and short stroke kept piston speed low.
