The Gorilla Clutch doesn't make the lever pullback any harder, it's the heavy duty spring included with the kit. And yes, the lever pull is a lot stiffer than you are used to, can't compare it to an old Harley cause i've never had one, but it's significantly more. You can get a lower tension spring with the Gorilla kit. I went with the Gorilla and stiff spring because of the power my bike is making. If you are going to change the clutch and don't have a big bore kit or other power adder more than the big 3, don't waste the money. Get a barnett clutch kit and either the stock or 1500 spring and ride.
