Is that a minibike on your meatball? :wink:
To be honest (a bad habit of mine), I'm not diggin' the jumbo meatball; it's large to the point of distraction (draws one's attention from the rest of the bike). Since a scaled down Lotus 25 nose styled fairing would be major PITA to make, I would suggest a square/rectangular (depending on fork dimensions) panel/number plate that covers the fork, triple clamp to triple clamp, full width of the fork (wrapping it around the ends of the triple clamps would add a nice touch, but not necessary). Paint this panel green; center a meatball on this panel, sized to leave green all the way around; you could have a short segment of yellow racing stripe above and below the meatball, if desired. Obviously, the fork could simply go naked. Just MY opinion, but it's YOUR bike! If it looks right to you, then it is right. Other than that one quibble, I think it's looking great. That "little" 125 really fills that frame; impressive looking. Keeping with the Lotus theme, are you going to wrap the grips in red leather? It would add a nice detail, IMO.
