From a laws-of-physics standpoint, changing direction of air/gas flow like that reduces the kinetic energy behind it...it slows it down.

In the case of exhausts, bends like that will add back-pressure.

 

ya i know, that's my point. while you need some back-pressure - adding more (and those bends would add much more than stock) would rob power wouldn't it? if more back-pressure was better - why would anyone run a full system?


anyways










i would rock all three of those!

 

Conrice,

That first bike isn't from the U.S. is it? I can tell by the Maxxis tires on it. Maxxis is a VERY popular mtn bike tire here in the States, but not a very popular road bike tire.

As for the back pressure, I'm not sure of the physics on it, but some engines do require a bit of back pressure in order to maintain a certain level of torque. While you do free up some HP with decreasing the back pressure, sometimes you will lose the torque you need. That said, a whole lot of torque isn't the main focal point for sportbikes.

 

not sure really if it is or isn't. but i can pretty much tell you that those aren't 17in. rims. i had an xs650.... those have to be 19's.... tracker style.... maybe that explains the tires? but it wouldn't surprise me if it was foreign. i started liking those old yami's because of this one bike - and now i can find it. i believe it was an xs650 or an sr500... or something - anyways - it was completely minimal - but it had ohlins USD front with radial brakes - supermoto (spokes) wheels - a perfect little cafe seat on it - and a gold tank.

i want to build one so bad. unfortunately, i owned the xs before i was into heavy modifications, welding, and fab. so it wasn't too special. but i'd love to buy and build another one some day.

 

just tracked it down (yes - pun intended) - it's from denmark

and i love this pic. it's just badass

i can't ever affording to own one of these.... outright cost, maintenance, danger of knocking it over or going down - so i'd never ride it, etc....


but it sure is beautiful.... and i do NOT think egli vincents are horrible - they're awesome- i could care less about the original frame if the egli is 10x better
