Levers with shorter reach.

As most of you know, the controls on the GRiSO are much firmer then say a Norge or V7. Even though I have the clutch lever adjusted to the shortest reach, after a couple hours of riding yesterday, the arthritis and old injuries in my left hand have it throbbing today.

The effort on the clutch lever for the GRiSO is probably double that of the Norge.

Are there aftermarket levers that will help decrease the effort required? Or at least one that can decrease the amount of reach necessary? I've never swapped out levers before, so have no frame of reference.

There is an Austrlian company that makes special clutches known as "Clakes". They are well regarded for their ability to significantly reduce clutch pull pressure. They also make a two lever version for both clutch and rear brake (mostly dirt bike application me thinks).
Worth a look.

I've got a pair of Pazzo levers on my GRiSO and they take some pulling
