lighter flywheel on a 620

[LowercaseJake]

Nichols flywheel resulted in MUCH more engine braking for me, so much so that it basically canceled out the effects of my STM slipper clutch. Wheelies at every green light now too. Would never go back to a stock flywheel. Might sell the slipper clutch, except I can't even imagine what the engine braking would be like without it.


Had a lightened stock flywheel on an old Indiana custom, I liked it as well.

The Evo engine's internals are generally so light, it's like trying to trot on a quarter horse that wants to gallop away. It feels best either accelerating or decelerating through the canyons and I love it!  I have kept stock high gearing with 6th as an over drive that loads it up on the highway to counteract this tendency so it only does 3500 rpm at 60 mph. The bike has also been carefully tuned to smooth things out at cruise. Remember that the factory lightened the Evo's primary gears, timing gears, crank, alternator and flywheel like a race motor. Some of my buddies on sports tourers hate it, but they're pussies.
I think the 620 has pretty light internals as is, so the effect would not be as dramatic as on a 900 or 1000DS.

funny you said that, i finally fixed the monster and after not ridden it for over a year, i took her out for a spin, and had the same thoughts. its a good and bad thing though. when your having fun with it its like an instant on off button, but it makes it real annoying in the city!

Wicked motors .
I think many of us are on the quest for more response and acceleration, but there's a point of going too far as nothing comes for free.

Has anyone here tried the Ducati aluminum replacement performance part  Flywheel ? It is supposed to shave two pounds off the stock one.

I would consider a Nichols flywheel if you go late model alloy. An ebay stocker machined down is an option. There are threads exploring the different flywheels available so I would do a search for all the pros and cons.
I had a DP flywheel on my old Superlight and it really helped acceleration.
