Dragonfly comes up with a new prototype of Yanmar's signature frame "motion". It's much lighter now ( 1.86 kg = 4.1 lbs ) and fully heat treated. Yanmar is testing the frame for a month now and afterwards it will probably go into production. You can see the frame in action for a moment in the Prova Cup video of psychobmx.com.
