I had the pleasure of a front seat view of him at the USA WTC and there is no doubt he still has enough + a bit more of what it takes. On the first day, (except for the first section ) he rode with confidence and determination and with Team Lampkin around him the whole thing was clinical and well excecuted.
I didnt see one instance when the machine couldnt get him up anything and if anything, the americans were commenting on how much power it had, ( especially if you saw the Scorpa 4f attempting the same stuff which was way off the pace. )
Im my humble opinion, the 4RT looks to be no longer at a disadvantage for the outdoor.. while people talk about the machines development, DL has had to learn new techniques and riding styles to accomodate it and to be where he is in such a short period of time tells me hes hungry for another title and the ambition is still there..
As the experience grows then so does the confidence so its still very possible
