vyrus had to have bought the rights to reproduce the 2D. look at the swingarm. they are mirrors of each other.
This sums it up well:
Quote from dnovo on MS:
Actually, it was the other way around. Vyrus was started -- and still owned by-- a former Bimota fellow who, after Bimota folded in the 1999 era, started Vyrus to continue the Tesi concept. When Bimota was resurrected by its present owners, the first new 'Bimota' was the Tesi 2D. In fact, it was developed by Vyrus with 50 models built initially, 25 badged as Bimota, 25 as Vyrus. The two companies went their seperate ways, with Bimota bringing out the first 'all Bimota' model a year later, the DB5. The current Tesi 3D is not a Vyrus project, and differs in many important points which include a different 'front shock.' The 2D has it located on the 'left' - as you sit on the bike- side and on the top just in front of the rider's knee. (Where it wacks you just fine in a hard stop.) The 3D has the shock on the right side, at the bottom of the frame and operates in an entirely different manner. The swing arms front and back are also different and the details of the hub steering are not the same.
Vyrus has continued to develop and refine the 2D and now offers the original 2v engine, a 999R and 1198R version and is talking about supercharging the latter. The suspension has also been upgraded in details but keeps the same basic concept as in the 2003-2004 models.
By the way, I am told that Vyrus and Bimota are no longer cooperating in developing the hub steer concept, having -- as they say in Italian -- split the blanket.
