It is my understanding that this "sidecar" set a "sidecar record"..........just proof of what I have been saying and posting for years........It also shows that 10% in the sidecar is not enough......I would think
60kg (132lbls) (as noted in the AMA rules) might be a better choice.....so the rig can somewhat be classified as a "sidecar"
As has been noted....."real sidecars have passengers"
