Insight
This is a race class that is along the lines of old days racing in the late 60’s and early 70’s. The 100cc class were the
toughest competition of the race day. It made us all better riders, and it made us better mechanics out of us.
Sometimes 150 to 300 riders would show up. If you won the 100cc class, you were the man, not an easy task.  
It’s called MT’s 100 Works Revenge for a reason, we all had factory bikes in that era, we just didn't know it. The
100cc class was the true beginning of Moto Cross in the USA, from porting to custom frames, swinging arms, pipes,
lightweight metals and so on. When the AMA passed the non works bike rule in 1986, all minds went to rest, we all
rode the same bikes, and imagination went right out the door. The fun slowly went away and our minds on making better
machinery.  MT’s 100 Works Revenge gold is to bring back the fun factor, get the minds working again on how to go
fast with only 100cc.

You want to run a disk brake, so be it, run outside the normal box, if you want to run box stock, that’s fine, enjoy.  Ride
the class with a small amount of rules to run by. If you are a whiner and complainer about this and that, you may not fit
in, but if you want to have fun racing like the old days again, I believe this is a great start for all.

This is just the start for all of us, yes, myself and the rules committee will have to make changes as it grows, we will
make it as clean and simple as possible. I know that I am going to have a blast with you competitors.
Best regards to all, hope to see you at the races.
