I am considering this mod for my S2R.  What is the general consensus for mainly street riding?  I  believe I've found a DP one for the same price as the Nichols one, any real preference?  Thanks

This is one of those subjects that have generated a mountain of discussion via the search function.

I know I was kept busy when researching whether or not to use one with my M944SS build. I ended up going with the Nichols but would probably opt for a lightened stock flywheel over the ultra light Nichols if I had a do-over. It's an extremely dramatic mod for a street bike.

Do you like wheelies or not?  Evil

If there were someone close to me, I would have mine lightened.  What's your reasoning on going with a slightly heavier one than the Nichols?  And is there any difference between the DP offering and the Nichols and a lightened OEM?

Fast Frank sells lightened OE flywheels with no core exchange necessary last I checked.

I sent my stock one out to Fox Performance to get lightened, then decided I wanted it lighter and got the sbk alternator adapter from Fast Frank Racing. Probably lost about the same weight as the Nichols, for more money. But, now I have a steel flywheel.  Roll Eyes

Sooooo...from what I can decipher, the OEM lightened one is steel, and the Nichols and DP are aluminum.  Can anyone educate me as to why it is preferable to keep the lightened steel vs the aluminum?

the nut came loose . . . when installed I used Ducati specs, these were later revised and torque was increased to 270Nm instead of 190Nm . . . it was sweet, but now, I will go back to OEM since no more DP lightened flywheels available . . . if I get an OEM one, might send to ML for lightening to my specs . . . In the future to come . . .

and a lot of $$$ has gone into repairing it . . .a year after and between having no time and taking care of customers bikes, . . result is, bike is still on stands . ..

They'll do it even if the nut isn't loose.

My theory is the aluminum expands and the flywheel can move back and forth on the splines the amount of the clearance between the two parts.

The aluminum can't take the battering.

Go with a lightened steel flywheel.

That makes me want to take the case off of my bike and look now. I've had a nichols for going on 7 years and never saw any shavings in the oil. But considering I torqued to 150ft/lbs with red loc-tite, I never expected to have troubles.
