New BOS Exhaust for 650 XChallenge

Done some more digging and this seems the baby

Full system

Can't post the file though, damnhik

Looks great and come in @ 93dB

Alloy and with heatguards

Supplied with a Foam Filter for the XC on the Racing version and the dyno gives it another 5hp, with a link pipe to ditch the Cat

From the file they sent me

BMW G650 X ’07 stock 42,7 Hp @ 6913 rpm 57 Nm @ 2120 rpm
BMW G650 X ’07 Bos oval Ec appr. 44,4 Hp @ 6513 rpm 59 Nm @ 2048 rpm
BMW G650 X ’07 Bos oval open + kit 47,1 Hp @ 6258 rpm 62 Nm @ 2022 rpm

As you can see on the graph the exhaust smoothens the torque and in combination with the racing kit it radical changes the power of bike.
Because this is a complete new design we have to produce a lot of new tools for the production of these silencers. We will do this as fast as we can and inform you about pricing and availability.

Available late March beginning April 2008.
