I need part # 28740011a or magneti marelli aei 450 b if i cannot find this part will be forced to part out bike

Is there a claer name or picture for this?

it is called the ignition module or power module two modules on either side of a heat sink.

you have a 907 ie then you can see it located next to the regulator and the ignition relays under the left fairing by the mirror. Und danke auch fur alles jeder kann hier nicht melden.

Now I know what yoiu mean. I can't see it, I am working in Serbia for some weeks.
I had seen these on Moto Guzzi Modells. May be they use the same.
I have no spare. good luck

all the Magneti Marelli setup of the 907 (MarelliP7) was used in many other automotive aplications so, maybe, you can find these parts right of the web (or ebay) through a car parts dealers

That part was also used in the 851-888 and I think in the first series of the 916 (Marelli P8)

In the cars, I think it was on the Lancia HF, 4WD, Thema, Fiat Croma, just to name a few.

I will ask a friend who is a Marelli specialist (and vintage car collector ) hoping he can help

On EBAY USA there is ONE attached to a wiring loom

worth giving the guy a call!!!

Thank you will try that

It's not that serious...

It would be "nice" to have the original but not absolutely necessary...
the ignitors are a problem to get now but were used on various cars and bikes around the time of production of the 907...so there will be some around - just need to look hard.

Also, they are a common thing...although they LOOK the same they AREN'T the same function...it is possible to use other model ignitors BUT re-wire the connections correctly to match the 907 requirements.

Hi Duc24u,

you may contact Carmo at www.carmo.nl
When I'm correct you'll need BB1105(A), BB1135

Personally I've no experience with this company, but would thrust them

Visited yesterday Ducaparts in Twello the netherlands with parts they have from desmantling damaged or broken bikes. Have a lot of stuff and prices are not like you see on Ebay. K&N filter for the Paso just € 20,- instead of €60 or more.

Perhaps drop them a mail, they speak English and with the partno now what you need. ducaparts at motofun dot nl
