Can anyone recommend a beefier clutch for my new 117 engine build. I would rather be safe than sorry.

 

If you are buying this as a package from a tuning shop, what do they recommend? You may need nothing more than a heavier clutch spring. There are some wonderful clutches available out there, but unless you are racing your bike, the stock clutch is pretty strong, with a little help.

To keep lever pressure down there are useful add-ons like the AIM pressure plate, which increases clutch plate pressure with speed.

 

I just rerouted my clutch cable to a more free flowing route and run a AIM 480 lb. spring. Pulls a little firmer than stock but less than a 300lb. spring with the old cable routing.

 

I'm currently running the Rivera Pro Clutch with the silver spring. I think there is one heavier spring available but I've had zero problems or slippage and I'm putting out around 125 ft lbs of torque. My builder uses this clutch on much bigger builds than mine with no issues. The clutch pull is not much heavier than stock and the pull lightens up when you have it all the way in which is great in traffic. I really like the way it feels. I probably could have gotten by with the stock clutch and heavier spring but at 90K it was time to replace the entire clutch assembly anyway.
