The later Bros 650 kept the 647 cc V-twin, aluminium frame and Pro-Arm single-sided swingarm, and stayed a Japan-focused naked middleweight. The listed change is a four-piston caliper on the single front disc for stronger braking. Honda kept it on sale in Japan for about a year after the export Hawk GT was dropped.
