How much should I pay for these wheels used?

[slowkitty]

May be able to score on a used set.  Looks like the ones below, not as nice but same pattern.  Allegedly magnesium.  How to tell?



Anyway, what do you guys think I should offer for a pair of that?

Cheers

If they are stock S2R wheels, they aren't magnesium... they're aluminum...
That bike there is an S4R, so I guess they could possibly be magnesium? but i don't think so...

That bike is "Black Fog", a 2002 S4. No stock Monster wheels are magnesium.

I bought a pair off of ebay several years ago from a pretty reputable ebay motors Duc parts dealer in Florida. I forget the outfit's name but the guy took real good care of me, was very upfront and stayed in touch via emails. I took off the stock three spoke wheels on my '97 916SPS and replaced them with the 5 spokers... aluminum was fine with me. They were a dark gray not black like your pic. When they arrived at Advanced Motorsports (I had them dropped shipped to AMS since my bike was already there) I just happened to be there and the owner Jeff Nash and I opened the box together. They actually weren't packaged all that well but the wheels were 99% good! I was real happy. Even Jeff was surprised and gave them his blessing. Paid $850.

My understanding is the way to tell the upgraded ones from stock is by the cut-out indentations on the spokes. You can clealy see them in the Black Fog photo above.

The stock 5 spokes on my MTS look like that but don't have the cut-outs. The aftermarket 5 spokes on my 748 do.

I don't know if they're magnesium or just a lighter aluminum rim...but I believe that is how you tell the difference between stock and upgraded.

Black Fog's wheels were off a Senna model SBK. (now powdercoated black)

This type of wheel was mounted on:  Senna SBK's, 998R sbk, SPS (?) and other R models? 

Although not rare -- they infrequently appear "for sale".  If you found a set you don't want, PM as I have someone wanting a set locally.

Thanks for the feedback .... appreciate it.

Wheels are presently on a 916 now. Guess the only way to know whether they are magnesium or not is to feel the weight?

As mentioned, no stock wheels are magnesium.

How to check...toss them in a fire. If it's magnesium, you'll know real fast.

Just an update. Found a set with inserts and they are Marchesini aluminium. 

So how much should I offer? Seller is asking for about US$700 for front and back.

 Marchesini Cast Aluminum and Forged Aluminum, have much different cost.

Marchesini Cast Aluminum and Forged Aluminum, have much different cost.

Yep. Big diff.

What are you trying to accomplish? 3 spoke to 5 spoke? Lighter weight? Bigger rear tire?

[kopfjäger]

Cast Aluminum is what is on most low end Ducati's. Almost all.  

[slowkitty]

Sigh .. next logical question ....

How do I tell the difference between cast and forged?  Pics and the education appreciated.

Cheers

If you have the wheels alone, you can weigh them precisely and know if they are Mg or Al.

I don't have any good photos. It is hard to explain, but the forged wheel has a much cleaner cut(?) You can easily tell when the cast and forged wheels are side by side. Someone may have some pics. If you go to www.motowheels.com and look under Marchesini you will see some good photos, plus all the weight diff., in cast and forged Aluminum.

You could just ask the seller.
