But the wheel is not modified in any way by adding weights, it is just balanced and yes the same can apply to a complete crankshaft assembly, in that you can mix and match rods pistons etc to balance a crank without having to modify the crankshaft.
But few people resort modifying by drilling or grinding their wheels to acheive balance.
So back to the rule, it says No modification of the Crankshaft, It does not say no balancing of the crankshaft asembly by selecting matchingcomponents

As for 916 wheels as far as I know a 916 front wheel is no different from a 620 front wheel and as the rule says
1.6.5 Wheels

Wheels including diameter and rim width must remain as originally produced by Ducati since 1992 for the 600/620 bikes.
Front wheel 17” X 3.5”, Rear Wheel 17” X 4.5”

There is no issue with using a 620 front or rear wheel in a 583 and if the 748/916 front wheel is the same part as a 620 it can also be used.
Did they fit any 620s with 5 spokes as found in the 996, if not then I doubt these would be allowed

Nope, not even the Capirex as standard - I've already checked.

Mind you, there are mag wheels listed in the DP catalog as suitable for the 620s - surely that complies with "originally produced by Ducati since 1992 for the 600/620 bikes.
Front wheel 17” X 3.5” " ?? Then I figured the 500quid would be better spent on improving ability through tracktime or Magners. Guess what I chose?

Drinking Magners while riding around a track by any chance
Would explain a few things

Maybe the wording should be changed to "originally fiited by Ducati since 1992 for the 600/620 bikes

To quote Sir Falon's Monster and SS book:

1998 onwards

Frame and Cycle Parts

" With Brembo wheels..........from the 916 and ST2 having larger diam. (25mm) axles.........."

".....the wheels were also lighter than before at 225 grams on the front and 800 grams on the rear"

It's easy to spot which ones they are if you compare them side by side.
However, ther is only one sort that will slot straight into a Monnie or SS without palava with the rear wheel bearings and wheel bearing spacers.

(and I'm not gonna tell you which one that is.......;-) )
