    Do you know why that seat brace is shaped like an upside down “U”?


    ....I do.

    You don't sound like you know what you're doing. It is unlikely you will get an endorsement for chopping a motorcycle here.

    To give the rear wheel clearance. You need that space so the tire doesn’t hit the frame under full compression. If you put a plate where your drawing indicates, you’re going to be in for a rough ride, and short tire life.

    I guarantee you that the first bike you posted doesn’t get ridden much, for very long, or at any speed. The last bike you posted (messy welds aside), at least braced the tail section adequately, He also cut it short enough and kicked the top bars up to allow what looks like enough wheel travel. However, this again is a bike that won’t be ridden much...specially in what appears to be the UK. That back tire will be slinging all kinds of road grime right up the riders back. He’ll be sporting a great skunk stripe after the first puddle.

    Remember Guys this was part of a package deal i got. I have found a pro welder with MIG, TIG & ARC. So nothing is impossible, i have even thought of going crazy sometimes and if it was possible to get rid of the bottom bar and reweld the shock support to the main frame like in the XJ600. Could that be and option or i would need a new swing arm & shock or can i use the same swing arm n shock ?

    I don't believe you should be cutting parts off the frame. This POS (pile of shit) bike you just posted is ridiculous. Look at the front suspension, where are you going to ride it with 1.5" of travel? The big fat knobbies, low clip ons and rear sets? What is this things purpose?Name:  1993-yamaha-seca-ii-diversion-xj600-custom-dirt-fighter-cafe-racer-tracker-1.JPG

    LOL. It even says POS on the tank!!!!

    Kumailrashid, keep in mind the key word around here is Function, function, function. We don’t generally give a rip what a bike looks like if it is useless as a motorcycle. We want it to perform better, handle better, be better than it was. Unfortunately as a new rider, you probably don’t know enough about the bike you have to know where to start, or if anything you do would be an improvement. What we can tell you is that by starting with mods aimed solely at changing the look by hacking up the frame, you won’t “luck” into any improvement
