Twin rotor twistgrip
Amal twin rotor twistgrip (313/6) for dual-carb setups on American-style handlebars.
This is the twin rotor twistgrip listed as 313/6, an Amal-made throttle assembly that operates two carburetors at once from a single grip. It shows up in the parts books under the control cables and American handlebars figure, which is the tip-off that this one was set up for the wider American-style bars rather than the narrower UK touring bend.

The twin rotor design means the throttle body has two cable drums instead of one, letting you run a pair of carbs off the same twist with individual cable adjustment for each side. That's the setup you'd need on any twin-carb machine where the carburetors need to open together but still get fine-tuned independently.
The alias 313/2NG is the same physical part under Amal's other numbering. Our catalog record only spans 1964 to 1965 across a handful of appearances, so if you're trying to match this to a specific bike, give us a call and we'll confirm fitment before you order.
