Ducati♔ may have ditched its carbon fibre design at the end of 2011, but the composite will be making at least a partial chassis return during the second round of the 2012 MotoGP season at Jerez in Spain.

According to Motociclismo.es Avintia Racing, which graduated to the premier-class under the new CRT rul💎es, will switch from an FTR to Inmotec chassis on one of Ivan Silva's Kawasaki-powered machines this weekend.

While the FTജR uses a conventional twin-spar aluminium design, the Motociclismo report states that the new Inmotec cha💖ssis is 'mixed carbon and aluminum'.

Colombian Yoꦫnny Hernandez, who defied the team's winter testing form with a creditable 14th place𒐪 in Qatar, will continue with the FTR.

෴Inmotec had intended to enter MotoGP with 💛its own 800cc MotoGP prototype and even penned Catalunya 2010 as the planned date of a wild-card race debut.

That never happened, but development continued and the BQR-run Avintia team spent post-2011 testing weighing up both FTR (🐈British) and Inmotec (Spanish) machin💦ery, before opting for the FTR-Kawasaki format.

But Avintia has made much of its Spanish roots, describing itself as "the first Spanish team to 💎develop a MotoGP bike, developed entirely in Spain" when confirming its place on the 2012 grid.

The switch to Inmotec is thu🌠s not i🦩n itself surprising, although the timing - so soon into the new season - is unexpected.

Silva, 16th in Qatar, was previously ♍the Inmotec test rider.

The premier-class grid will now contain threౠe different chassis materials; aluminium, st🐈eel trellis (Ioda) and carbon fibre.

Silva isn't the only Avintia ri🀅der rumoured to be switching frames this weekend, Moto2 star Julian Simon is said to be swapping his FTR for a Suter.
