here is my 2002 F650 gs... not a classic like all these other nice bikes, but it's all I have to work with right now...
last weekend I have been at the BMW Boxer meeting in Freudenburg, Germany.
There have been some interesting Beemers:
This one was even for sale, but I haven't asked for the price:
More pics from the meeting can be found on my website R100.Net
here is my f650 gs, not one of your classic bike bikes... but fun anyway
I've always wondered - why do the cafe racers sometimes have the elaborate re-routing of the exhaust headers?
The one that started it all, swept back pipe with a "goldie" muffler........
Help a dense yank out here - so the reason for the elaborate exhausts are to emulate the first cafe racers - no performance boost or any other practical reason? I'm a geek - I have to know these things or I loose my membership card
A well-designed header system can reduce backpressure and increase flow-through. Usually that'll give you something, mostly at the top end. But the design has to have the tubes matched in length pretty well to be very effective, that's why sometimes they seem overly convoluted. But not every convoluted system has necessarily been so carefully designed...
At first it was reduced weight, more ground clearance, cool factor and less back pressure. Reduced back pressure does not always mean more power. Later cosmetics and truly better performance came into play.
That is pretty cool. Got more pics?
Just built this one( 500cc BSA cyclone)
www.2wheelconnection.com for details. It is sold, BTW.
also pic of a BMW that I modded on the site.
My "cafe racer" at Laguna Seca 11/04:

Here's my 72' R/75 w/ dirt bike in the background.
Just checked out the Rockerboxer site mentioned on page one and found my old bike that I built on it
Just took a peek, what the heck is this??
Slash2 powered minibike. First generation pocket-rocket? I like!
How about a pic of two that reside in my garage ?
Anyone know where I can get some nice clubman bars for my R90s?
Any bike parts catalog, and lots of bike shops have them in stock.
I just got some off craigslist for $20.
