Things needed to change an 06 Attak to 144x1.75"?

[bellofello]

Hey everyone, new to yamaha this year. Still getting used to my attak. Liking it so far.

I was thinking of getting a 144" timbersled rear and a VA 144" bumper kit.

Just curious as to what is needed to clear a 1.75" track. I'm assuming smaller drivers or something of the sort. Has anyone done this?

Thanks.
