  1. Basically, this thing work like VTEC but changed little bit by Yamaha. Ihope I get it right

  2. Mungkin ini alasan Yamaha tidak mau membuat mesin DOHC . Tapi lebih memilih mengembangkan mesin SOHC

  3. Its seriously time for yamaha to make a 250cc short stroke 4 valve single cylinder VVA engine. How long are they gonna milk this little 155cc vva engine?? Until the year 3000???

  4. I mean it’s only applied on the intake. So there’s no difference about the sound, unlike Honda’s VTEC on bike like CB400F.

  5. Its funny to think that this VVA technology is copied from Honda’s VTEC technology, and yet Honda did not adapt this technology in their motorcycles especially scooters like the PCX, Click and Airblade.

  6. For those who wonder where it came from. Basically it’s originated came from car long time ago. Like the Toyota VVT. it work the same.
