Suzuki showed more of its hand for 2014 recently with the announcement it would test its new 1000cc GSX-R prototype in June along with existing MotoGP factory teams Ducati, Honda and Yamaha at Barcelona.
It appears Suzuki isn't the only manufacturer eyeing a return or arrival in the premier class.
Kawasaki, which left MotoGP as a works factory team after the 2008 season, may be sniffing around a potential return to the World Championship.
Works teams returning to MotoGP probably will need to form alliances with existing teams, as Dorna boss Carmelo Ezpeleta has said no new grid pots will be created in 2014 for the return of Suzuki. The same rules would apply to Kawasaki, too.
Officials from Claiming Rules Team Forward Racing have made no secret that they would like to attach to a factory in upcoming seasons. Forward owner John Cuzari told Italian media that the team has expanded to two Kawasaki-powered CRT's this season, with rookie Claudio Corti joining veteran rider Colin Edwards II, as a shop window for the team's readiness to become a factory outfit.
Cuzari also confirmed he already has started discussions with Suzuki and - surprise, surprise - Kawasaki about becoming the foundation for their factory returns to MotoGP.
Aspar is believed to have an inside line with Suzuki since Aspar CRT rider Randy de Puniet will serve as a test rider this year with Suzuki. But Forward switched from BMW to Kawasaki power this season, which will strengthen its bonds with the Japanese manufacturer.
Indian manufacturer Mahindra also has long-range sights on the premier class. Mahindra has fielded a team in the introductory class of the World Championship since 2011, providing factory bikes this season to Miguel Oliveira and Efren Vazquez in Moto3.
"Our goal is to advance in the Moto2 class and then in the MotoGP class," Mahindra Team Manager Massimo Biagini said to German media. "But first we need to prove our potential in the Moto3 World Championship."
That could take some time. Mahindra finished ninth among 11 constructors in Moto3 last season, scoring four points. KTM won the Constructors title with 346 points.
