. Amongst my collection of a dozen or so bikes is a pair of Mongoose Beasts in black (bought 'em on a killer close out deal). I get a kick out of riding these buggers around but I'm getting the itch to start a few mods on one of them. Maybe this is a goofy idea but I'm thinking about a smaller width rim and tire for the front. What would be the best way to go about the front wheel thing ? Best maybe to just find another front fork and go from there ? Excuse my ignorance when it comes to bikes ... I guess I'll be a work in progress. I've mostly been restoring antique vehicles and tractors for 45+ years and have never really done much in the line of mod'g bikes. So it's high time to start I think. As you can see I've been lurking on this forum for quite a while trying to learn a thing or two about a thing or two.
