There’s growing speculation that Yamaha maybe on the brink of announcing a new revised R1 sport bike after the company filed for four new trademark registrations in the U.S. and Europe earlier this year.

Essentially there are four names that have been picked by Yamaha, as there are different models for the U.S. and other markets. However, it seems probable that the Japanese manufacturer is looking at doing something big in the liter segment after registering the R1S and R1M names in January here with the U.S. Patent & Trademark Office and the YZF-RIS and YZF-R1M names in Europe.

Of course there are no technical details or launch dates for any of these models. However, this pair of new names could mean that the R1S might become a sportier version of the company’s existing flagship, the R1, perhaps with different electronics and suspension over the existing model.

This would then mean the R1M maybe a more track-focused bike with a set-up derived from Yamaha’s MotoGP bikes. Honda did exactly this not so long ago with the introduction of its CBR1000RR SP that comes with up-rated suspension and brakes, but at an additional price, and is designed more for track use in mind.

All of this is just wild speculation on our part and instead of two revised Yamaha R1 models, Yamaha might well be looking at launching a whole new series of R1’s altogether, which would be even more exciting. We’ll keep an eye on this to see how this develops.
