I have used YZ/IT Yamahas and parts as fill, in the berms and jumps of my practice track, as I have found that is all they are good for

. They are useful in these situations because it can simulate actual racing conditions

. Although , I must say that the 43mm forks and TLS front brake can come in handy for use on other bikes, as they work better than the front ends of my Huskys

.
I also have to say that the above is just a poor attempt at humour, as I don't want some rabid Yamaha fan sending Wes (aka Rubberneck/Bigbird) around to assassinate me, using his skills learned in the SAS
