Big Wheel Addict

Salut mes amis,

I was some weeks before the BWD on a performace stand with my TW217.
I've added the chart from the TW200 (org. Yamaha cataloge), to have a good comparison base.

Here are the download links for the chart:

big 2300x1488px (http://www.tw-parts.com/macbig2k1/bilder/pruefstand/2009.05.09-TW217-org.-YZ450-Akra-TW200_gross.jpg)

Please ask me, if you have a question.
I will try my best for a good answer.

Regards, Sebastian

I am planing in 2 or 3 weeks a big session on a real Dynojet performance test bench, because other results are from a very cheap test bench.
These bikes:
TW125 (from Petra)
TW200 (org. from 1997)
TW200 (my motocross)
TW217 (my supermotard)

and these exhausts:
org. exhaust
open exhaust (YZ450 muffler)
Akrapovic SlipOn (simulated by the racing system with the org. header pipe)
Akrapovic complete racing system
