You can always use a gsx box section alloy arm. They used to be the upgrade back in the day and look pretty cool too. Plus you can put wider rims on those spoke hubs! You can get a 5 inch rim on a z900 rim for example. Not sure about the Suzi ones.
It’s hard to measure with the 90 degree bend in it but I reckon 38 1/2 inches. So need one that it 39 1/2 or 40. That is the length of the cable not the sheath. The length of the sheath is 32 1/2 inches
Before I send Venhill Cables 60 quid, does anyone know an off-the-shelf throttle cable that fits the EFE but is about an inch longer?
GSXR cables are different at the throttle end and GS cables are different at the carb end.
