Yamaha MT-09 Y-AMT 2025

Yamaha's new automated manual transmission in the MT-09 offers an interesting alternative to manual shifting. In "AT" mode, automated clutching makes riding easier, especially in city traffic, while "MT" mode preserves riding pleasure and sportiness. The neutral gear is now in first position, followed by gears 1 to 6, which enables smoother gear changes. Although the Y-AMT technology requires some familiarisation and there are limitations, such as the lack of "sliding" by pulling the clutch, yet the driving experience remains dynamic.

Easier riding in city traffic

Maintains a sporty driving feel in "MT" mode

Smooth gear changes thanks to new gear arrangement

Keyless ride included

Familiarisation time required No "gliding" through the clutch before corners

system could be more "obedient" or flexible in automatic mode
