The MT-07 engine's debut was what I was waiting to see from Yamaha. On paper, as with the 09, it looks good in every way.
Not sure it will work in an XT690 though? With its chunky wet sump and bulky DOHC top end it makes for a very tall motor. It'll would be difficult to accommodate in an off-road style frame and maintain an effective balance between ground clearance and low centre of gravity...
