Just read in TMX that Scorpa are thinking of going all Four stroke, Yamaha engines I presume? anybody in know ?

heard similar from my swiss friend . feb mar 2005 ?

I've heard similiar to munch, they'd might as well carry on with the SY250 though as theres not a lot wrong with them.

They might want to discontinue the SY/TYZ lump. Its getting long in the tooth and expensive for both Yamaha and Scorpa.

Don't think there is anything wrong with the TYZ motor, it's penty good enough to keep the SY competitive for a while yet, but perhaps the question is how much longer can/will Yamaha supply it. It could be that issue that forces Scorpa down an all 4-strole route. (I have no idea obviously, just a possiblity)

Hi all,

Yes, Scorpa will have a their prototype four-stroke next year, which I am told will be the basis for the 2006 Scorpa. As far as I know the SY will be available on an order only basis - ie, if you want one and they have the parts they will make one. Whether this applies to one offs or larger shipments I don't know.

As for the new Scorpa four-stroke motor - it is a %&%^^&&^. Sorry, I do know what it is but I promised Phillipe (Owner of Scorpa) and Jean-Marc (sales/marketing/export manager) that I wouldn't tell. But it is an engine from Yamaha.

Cheers,

As the World round is right next door to the factory I guess that this would be a good time to present it.

As reported in this topic.

thats looking like another nail in the coffin for two strokes then ! just hope they dont use the TTR 250 engine its 'quite large' or will it be an adapted WR-F engine , electric start trials bike anyone !!

WR is the donk educated guess.

I sure hope that Scorpa/Yamaha are smart enough not to use that top-heavy DOHC YZ/WR motor.

like i said dude its that (wr/yz) or the ttr250 motor, i dont know of another yam 250 motor unless they use the xt 250 motor

What makes you think that the trials engine will be based on an existing motor you know about?

Could be a totally new motor. Could be a new water cooled top end grafted onto the existing TTR125 bottom end, or a variation on the SY250's bottom end.

good point , out trick honda .... COOL

With Yamaha, Scorpa and Mick Andrews involved in it's development, I suspect it will be a worthwhile contribution to the 4-stroke trials market.
