That has GOT to affect cornering clearance. Sheesh!! I cry every time I see a perfectly good sportbike that got butchered to add an extended swingarm and a ridiculously fat rear tire.
There's art, there's practicality, and there's style.
Some of the poor machines in that video fail on all accounts. But.... to be fair, I have low opinions on a lot of art that others seem to like, or believe they are supposed to like.
For example at 2:55 in there's a nicely done tail piece. Not what I'd do, but it's well done. Other examples of hammer work & 'glass are horrific.
I actually like Cafe bikes. Converted my GS750B to one. Then back. Some of the bikes in the vid are ok. Not for me, today, but you're only 19 once, right?
