YAMAHA'S YZF-R25 will be launched on May 20, according to an official teaser website for the new model.
The parallel-twin 250cc sports bike is being billed by Yamaha Indonesia as a 'baby YZR-M1' MotoGP bike.
The Indonesian-built R25 is expected to be followed by a 300cc version for Europe called the YZF-R3, to take on Kawasaki's Ninja 300 and KTM's forthcoming RC90.
Yamaha is also expected to use the platform to further expand its 'Master of Torque' range, with an MT-25 based on the same frame and engine, just as it has used the R125 as the basis for the recently unveiled MT-125.
Yamaha Indonesia's teaser site shows the bike partially obscured by a garage door, while a message says: 'The baby YZR-M1 will be born 20.05.2014.'
The R25 is expected to make 35-37hp.
A 'concept' version with no lights was revealed at the Tokyo Motor Show in November. The final production version will have twin headlights.
One Indian bike website is speculating that it could have a single-cylinder engine instead of the widely anticipated parallel-twin.
