Cool to see that the MXGP Factory Yamahas of the WILVO-Team now feature these RAM-Air airbox covers....just like the VRP aluminium gas tanks for Honda CRs back in '88 / '89 (VRP = Verona Racing Parts from Italy)
Now let's have a look at my 1989 VRP Mugen Honda CR 125....those air-channels in the gas tank get feeded through the vented front numberplate and draw air down into the large aluminium airbox. Speaking of aluminium - this '89 VRP already had a aluminium chassis...8 years before Honda actually offered the first aluminium framed bike in '97.
Mr. Carlo Verona was waaaay ahead of the time !
Already in 2018 some Factory GP Teams tried similar air inlets: Kawasaki and TM....inspired by VRP
Dixon Racing Kawasaki:
TM did the same on Samuele Bernardinis Factory 250
The 2020 TM 300mx has a chute on top of the gas tank right to the air filter. The current tm 2 stroke models still have the chute but it is a little different as it only pulls air from one side of the gas tank and the volume is smaller which I believe speeds up the intake charge.
