Next-gen Yamaha R1 spotted testing!

Quiestest, fastest, least polluting-est R1 caught on video

THIS spy video shows what we believe to be a new Yamaha R1.

Yes, it might look like the previous model, but we're sure it's the next-gen R1 and by the looks of it, Yamaha has worked hard to make it Euro4 compliant by cutting back on emissions and noise.

Wonder how much power it makes...
