I am glad that this is getting attention. I have alot of time and research into my FXT and FXS in order for them to work with the frame rails I chose. A third bearing did not add much money or time in fabricating. But in my mind I know that mine are legal. So I guess if the rules change to take the width on stock rails out of the equation, then I agree with George that we should be able to fabricate our own frames. The problem I see with that is then they turn into gokarts and that is not what the majority of us want.
2012 rules
FXS and FXT basic rules:
2. CHASSIS: Frames, parts, must retain original manufacturers (OEM) specifications (no
chopping) re: wheel base, length and width unless modifications specified in particular class.
Material (steel) may be added for structural strength. It is recommended that front axles be
bolted or welded rigid eliminating the stock pivoting. No rear engine lawnmowers must be front
engine traditional style lawn tractor with a hood covering the engine and rear fenders. No
handlebars, to prevent a racer from being pierced in the event of a roll over. All tractors must
have a 2" min ground clearance. All tractors must have been a factory built lawn cutting tractors.
FXS

of chassis to install after market clutches, gear box, seats and axles allowed, must retain
original OEM wheel base.
FXT

safety shield or stock cowling from the driver. Discreet chassis modifications allowed for axle
installation and reinforcement. Scalloping of frame allowed in getting seat down on tunnel type

The only thing that I see that has changed from last year is the ride height. It seems pretty black and white on what is legal to do to the width and length.
