But when you are sitting this will cause a lot of fatigue for your clutch hand and fingers. A longer clutch arm. Some riders just cut the 'clutch arm' and weld or screw in a longer section to provide more leverage. It doesn't need much extra length to make a big difference.

These are sometimes called 'stunt clutches' and rely on extra leverage as well. If your clutch has six bolts, you can try either two, four or six lighter springs. It's easy to check for clutch slipping. Just accelerate at full throttle through all the gears on a sealed road and check for slippage. An extreme test is to pull the clutch in while in top gear, rev the engine, then drop the clutch and see if there is any slippage. The second method. If your clutch has six bolts, you can simply remove two bolts and springs. Your clutch will be 33% lighter. Again, this is completely at your own risk. I have tested this on my enduro motorbike over the past year with no problems. Personally I would not do this on a road or adventure motorbike. And a 33% reduction will probably cause clutch slipping on most motorbikes. Does it unbalance the clutch itself?
Some levers provide adjustment so you can adjust the lever to sit further or closer to the handlebar... but generally the lever will need a lot of movement to fully disengage the clutch so short fingers may have trouble.

Cable clutches become tougher as lubrication dries up, or dirt slowly creeps in. Remember to lubricate your cable on a regular basis. Beware of manufacturers claiming up to 50% less pull. Generally you can only expect about 20%. Do your research. Some owners report certain brands were a waste of money. A similar mechanism is the 'Easy pull add on'. It's also called an 'easy pull clutch kit', or easy pull clutch system'. Again it's using extra leverage. These are usually mounted at the handlebar and personally I don't like the added complexity. Again, beware of ridiculous claims such as 80% reduction in clutch pull. Who are they kidding? One potential advantage is your clutch cable becomes longer which could be useful if you fit bar risers.
