Light weight flywheel

[Kobiashi]

I have a 2012 1100EVO Monster. I noticed Ducati and several other after market vendors manufacture light wieght flywheels for Monsters up to 2011. My local Ducati dealer told me they have a machine shop that will turn down the stock fly wheel on the older Monsters and would be happy to do the same for my 2012 1100EVO, however they don't know why Ducati doesn't offer a light weight one for the 2012's. Is the 2012's fltwheel already considered light weight? Has anybody else made this mod on their 2012???

Ducati said that the Evo got a lighter flywheel (than the 1100) along with other engine upgrades.

Maybe they think it's light enough...

One is from the EVO1100 and the ohter from DS1100.

The SBK flywheel is lightened from the factory as well.

Thanks guys, the photos show there isn't much, if any, extra material to remove...

[He Man]

no but if its spinning 5000 times a minute it makes a world of difference.

Only 5000?

I had to get my RPM cutout lifted by 1500 because I kept hitting it in 2nd & 3rd riding to work. The low cutout really puts a stop to fun wheelies.

A lightened flywheel is a good thing if you like to race to the next corner. not real great in traffic though.

There is always one person who says this WRT lightened flywheels, whether you are talking motorcycles or cars. Yet the predominant opinion is they do not negatively impact street riding/driving.

having a lightened flywheel (alloy) I can say that the constant need to blip the throttle in peak hour traffic and the relative inability to maintain a smooth low rpm throttle-clutch-crawl through traffic, compared to the standard flywheels smoothness and low rpm 'stability' for combating city crawling traffic, I'm still firmly in the camp of standard flywheel for commuting.

nothing wrong with the lightened wheel, it's just a pain in the arse to ride the bike in heavy traffic, compared to a standard one.

if you're not riding in traffic, and using the bike only on weekend rides etc, then it's not going to annoy you.

So what you should have said in your original reply would be as follows:

"A lightened flywheel is a good thing if you like to race to the next corner. BUT FOR ME, not real great in traffic though.

Not every rider/driver is bothered by such trivialities.

Thanks guys, I've run lightened flywheels in drag boats and street cars over the years and know the pros and cons of running a lightweight flywheel. My original question was, has anyone actually installed an aftermarket one, or had the OEM flywheel lightened on a 2012 1100EVO? If so, were you happy with the results???

[JoeB]

I have one, it's Alloy.

It's ¼ the weight of the original steel unit.

I like the fact that it just spins up quickly. But like I said before in my previous post before I was flamed for stating the obvious:

in traffic (i.e. stop-start low speed crawling - like peak hour traffic from work to home etc) it can be a real pregnant dog.

I have had the bike stall because of clutch vs rpm early on until I got used to the revs needed to take off, the downside is wheelies off the line in traffic, which attracts the local constabulary like nothing else.

So I do most of my riding outside of peak times, it's the best way.

If I was commuting, I'd think about a lightened wheel, but not a super light one. I think the DP one might be OK, but  you only need to take about 0.5-1kg from the mass to make a Drastic  difference in engine behaviour.

i tend to say that a light flywheel shows up poor tuning.  ime a well mapped bike will run just fine with a light flywheel.

i'd expect the light flywheel to be a bit of an asking for trouble thing on a closed loop bike, given the total lack of tuning control you have with them.

Yes, this is the case with my bike at the moment. It still has the standard ECU in it coping with all the mods. The DP ECU might fix a few things, but will have to wait & see.
