DP Flywheel

[Quackzilla]

i don't have a LW flywheel yet, and will most likely go with the Nichols, but found this of interest.

i've read that some people that bought/installed the DP flywheel needed to have it machined in order to work. I had emailed a question to SSR (who makes a LW flywheel) to see if there's would fit the HM. Here's the reply that i recieved:

"We checked the ducati catalog, the hypermotard part number is 276.1.025.1C, our flywheel fits the 276.1.025.1B for sure. please check with your ducati
dealer for the fitment."

so for those of you that have had fitment issues, do you know which flywheel you recieved/used?

Nichols... no guesswork or screwing around with machining.

i know that, the Nichols is lighter, less expensive, and fits

The DP flywheel has to be machined to fit. I just went through this, my bike is in the shop now and they had to have it machined so it would fit against the starter gear. Picking it up today - will report on the difference

i know that you had to get it machined to fit, the question is which part did you recieve/use

276.1.025.1C is the for the HM
276.1.025.1B is for the others

not sure on Ducati's numbering, but does the letter represent a change to the part?

Or you can machine your stock one down from around 5 pounds down to 1.9 pounds ($75 exchange or have done locally) and no aluminun splines to worry about, I have seen more than a few aluminum splines striped on the crank so the starter sprag just spins then your bike wont start and aluminum flakes are in your oil.
Since the starter sprag and rotor are bolted to the flywheel it is more than just a weight. We often leave street bike flywheels a little heavier (3 lbs.) to leave some flywheel effect, about where the stock 848 is. 2C

Why not just leave the guesswork and go with the Nichols? It's 9oz, takes about 20 minutes to install and you can just forget about it...



The issue with the splines was with the early motors. They don't have a problem any more.
And, it revs so nice. I wish there was one lighter......

20 minutes to install the flywheel?

Where are the instructions? Is this something that the average Joe can do in his garage?

I ask this question with all due respect to your shop and your shop's reputation:

Are you saying that the Nichols flywheel has a tendency to strip the splines? Or are you saying the DP flywheel - that has to be machined to fit - has a tendency to strip the splines?


I recieved a Nichols flywheel for my 916 and it weighed NOTHING. I returned it unused because I got the Hyper, and the one that came for the Hyper was far heavier than the one for the 916. However, both appeared to be machined out of rugged, billet aluminum stock ... not some soft, play-doh aluminum. Please expound on the differences between machining the stock flywheel and going with a Nichols alternative.

No not average..

you need the puller. most shops charge 1 hour of labor which is totally worth it.
