Evolution GT750K
1973: Suzuki GT750K Visible clues, front disc brakes chrome radiator covers, GT750 badges on side panels. paint colours and schemes change, carburettor mounting from bolt on to to barrels, to clamp mounted rubber connectors. Fins on exhaust clamps and head changed slightly, other minors mods to crankcases and frame. one worth mentioning is the change to the SRIS (Suzuki Recycle Injection System) pipe routing.
Much the same performance as the J except in stopping distances. In the dry much better, in the wet much worse!!
