FangShui & Others,

I was wondering if extending the swing arms has any functional purpose?
Or is it mainly aethetics only. If aesthetics only, I don't like the looks. :(


Also noticed that they replaced the forks. I always thought that Inverted
forks are superior to the regular forks. I wonder why they replaced it? :)

The longer wheelbase a stretch will give you makes for greater straight-line stability (especially at higher speeds) but will have slower handling and require greater effort to steer the bike, especially in the Twisties. Think Cruiser type handling. Though on the Z125, even with that stretch (looks like about 6.5" to me), the wheelbase would still be only c. 1379mm, which is in the sportbike range.

I think stretches are about 99.9% for looks, especially for show bikes.

Those forks look substantially beefier than the stock forks, so would have less flex than stock. Advantage? They could improve handling a bit, maybe. Probably also mostly for looks on this bike, though. It would be difficult to do wheelies on that Z!

Upside down/inverted forks usually are larger diameter and thus stiffer, with less flex and greater torsional rigidity. They also generally have less unsprung weight vs standard forks.

Also, that looks to me like a 6.5" stretch and a 4" stretch is pretty commonly thought to be the maximum safe limit for a bike that's ridden regularly at typical road speeds (which for this bike, in stock form, would be in the 25-65mph +/- range)

Interested in getting this done myself, sometime down the road and the speeds it allows for is good for my mostly city and somewhat highway riding. Just have to stay on the furthest right lane for safety and sticking with the slower flow of traffic.

What's up with that exhaust? Is that something custom or a production part? It's absolutely gorgeous and I'd love to have it for mine.

I do notice one thing! The front light and the turn signals are not same as the US bikes.
Turn signal is high on US bikes vs low on that one.
And the two tabs left and right over the head light is chrome on the pics,
as far I know there black on the US bikes?

Looks like an aftermarket Thai headlight with flush mount signals.
That exhaust is almost certainly a Fake Yoshimura, since Yoshimura does't make or sell one that looks anything like that, at least not one I could find on the Yosh website or through Google images.

Here is another one of those fake Yoshimura's.

Build: Slevin's build - Page 18 :crying:
His build list says it's a "Custom Adapted NSF100 Yoshimura Cyclone Titanium Underbody Exhaust."

And here it is, a Special Order Racing Exhaust that Yoshimura DOES sell, for $859.00 USD.

Yoshimura HONDA NSF100 Exhaust System

I stand corrected and hang my head in shame, :frown2:
