Yamaha has just released this video giving the first official confirmation that a new R1 will be unveiled early next month.

Titled 'Nothing stays the same', the video shows the new bike being put through its paces on track, along with a few comments from Yamaha riders Valentino Rossi and four-times AMA superbike champion Josh Hayes.

In true teaser-video style, not much is given away in terms of specifications. Perhaps the most telling part of the video is the clip showing a full-colour digital dash with numerous acronyms denoting traction control, stability control, launch control, and 'LIF'.

It also shows what looks like a g-meter and optional riding modes, with one of the track riding shots revealing that the underseat exhaust from last year's R1 has been replaced with a belly-mounted unit.

The video description says: 'Everything has changed except the name. Designed with total freedom. Built for ultimate control.'

Yamaha released its first teaser for the R1 just after Intermot show. The video featured sketches of single-sided swingarms, large brake calipers and fully adjustable forks.

The 2015 bike was initially rumoured to use an updated version of the four-cylinder crossplane crank engine found in the current R1. However, the sound clip featured in the video of the new bike approaching redline, suggests they may have returned to a conventional firing order.

As well as styling changes, the new R1 is expected to be available in two variations; a racing version rumoured to make 230hp and feature revised traction control and electronic suspension, and a standard version making less power with dual-clutch transmission available.

Yamaha will unveil the 2015 YZF-R1 at Eicma show in Milan on 3 November.
